Attempts to locate and call a method dynamically added to a class at runtime if a default cannot be located

You can add extra methods to a class using Extensions}, {@link Object::createMethod() or Object::addWrapperMethod()

Adds any methods from Extension instances attached to this object.

All these methods can then be called directly on the instance (transparently mapped through __call()}), or called explicitly through {@link extend().

Register an callback to invoke that defines extra methods

Return TRUE if a method exists on this object

This should be used rather than PHP's inbuild method_exists() as it takes into account methods added via extensions

Determines if a custom method with this name is defined.

Get meta-data details on a named method

Return the names of all the methods available on this object

Get all public built in methods for this class

Find all methods on the given object.

Add all the methods from an object property.

Add all the methods from an object property (which is an Extension) to this object.

Add a wrapper method - a method which points to another method with a different name. For example, Thumbnail(x) can be wrapped to generateThumbnail(x)

Add callback as a method.

Allows user code to hook into Object::extend prior to control being delegated to extensions. Each callback will be reset once called.

Allows user code to hook into Object::extend after control being delegated to extensions. Each callback will be reset once called.

Adds any methods from Extension instances attached to this object.

All these methods can then be called directly on the instance (transparently mapped through __call()}), or called explicitly through {@link extend().

Add an extension to a specific class.

The preferred method for adding extensions is through YAML config, since it avoids autoloading the class, and is easier to override in more specific configurations.

As an alternative, extensions can be added to a specific class directly in the Object::$extensions array. See SiteTree::$extensions for examples. Keep in mind that the extension will only be applied to new instances, not existing ones (including all instances created through singleton()).

Remove an extension from a class.

Note: This will not remove extensions from parent classes, and must be called directly on the class assigned the extension.

Keep in mind that this won't revert any datamodel additions of the extension at runtime, unless its used before the schema building kicks in (in your _config.php). Doesn't remove the extension from any Object instances which are already created, but will have an effect on new extensions. Clears any previously created singletons through singleton() to avoid side-effects from stale extension information.

Get extra config sources for this class

Return TRUE if a class has a specified extension.

This supports backwards-compatible format (static Object::has_extension($requiredExtension)) and new format ($object->has_extension($class, $requiredExtension))

Calls a method if available on both this object and all applied Extensions, and then attempts to merge all results into an array

Run the given function on all of this object's extensions. Note that this method originally returned void, so if you wanted to return results, you're hosed

Currently returns an array, with an index resulting every time the function is called. Only adds returns if they're not NULL, to avoid bogus results from methods just defined on the parent extension. This is important for permission-checks through extend, as they use min() to determine if any of the returns is FALSE. As min() doesn't do type checking, an included NULL return would fail the permission checks.

The extension methods are defined during __construct()} in {@link defineMethods().

Get an extension instance attached to this object by name.

Returns TRUE if this object instance has a specific extension applied in $extension_instances. Extension instances are initialized at constructor time, meaning if you use add_extension() afterwards, the added extension will just be added to new instances of the extended class. Use the static method has_extension() to check if a class (not an instance) has a specific extension.

Caution: Don't use singleton()->hasExtension() as it will give you inconsistent results based on when the singleton was first accessed.

Get all extension instances for this specific object instance.

See get_extensions() to get all applied extension classes for this class (not the instance).

This method also provides lazy-population of the extension_instances property.

An implementation of the factory method, allows you to create an instance of a class

This method will defer class substitution to the Injector API, which can be customised via the Config API to declare substitution classes.

This can be called in one of two ways - either calling via the class directly, or calling on Object and passing the class name as the first parameter. The following are equivalent: $list = DataList::create(SiteTree::class); $list = SiteTree::get();

Creates a class instance by the "singleton" design pattern.

It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).

Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).

Gets the uninherited value for the given config option

Construct a new DataObject.

Check if a field exists on this object or its failover.

Note that, unlike the core isset() implementation, this will return true if the property is defined and set to null.

Get the value of a property/field on this object. This will check if a method called get{$property} exists, then check if a field is available using ViewableData::getField(), then fall back on a failover object.

Set a property/field on this object. This will check for the existence of a method called set{$property}, then use the ViewableData::setField() method.

Set a failover object to attempt to get data from if it is not present on this object.

Get the current failover object if set

Returns true if the given field exists in a database column on any of the objects tables and optionally look up a dynamic getter with get().

Gets the value of a field.

Called by __get() and any getFieldName() methods you might create.

Set the value of the field Called by __set() and any setFieldName() methods you might create.

Merge some arbitrary data in with this object. This method returns a ViewableData_Customised instance with references to both this and the new custom data.

Note that any fields you specify will take precedence over the fields on this object.

Returns true if this object "exists", i.e., has a sensible value.

The default behaviour for a DataObject is to return true if the object exists in the database, you can override this in subclasses.

Return the "casting helper" (a piece of PHP code that when evaluated creates a casted value object) for a field on this object. This helper will be a subclass of DBField.

Get the class name a field on this object will be casted to.

Return the string-format type for the given field.

Render this object into the template, and get the result as a string. You can pass one of the following as the $template parameter:

• a template name (e.g. Page)
• an array of possible template names - the first valid one will be used
• an SSViewer instance

Generate the cache name for a field

Get a cached value from the field cache

Store a value in the field cache

Clear object cache

Get the value of a field on this object, automatically inserting the value into any available casting objects that have been specified.

A simple wrapper around ViewableData::obj() that automatically caches the result so it can be used again without re-running the method.

Returns true if the given method/parameter has a value (Uses the DBField::hasValue if the parameter is a database field)

Get the string value of a field on this object that has been suitable escaped to be inserted directly into a template.

Get an array of XML-escaped values by field name

Return a single-item iterator so you can iterate over the fields of a single record.

This is useful so you can use a single record inside a <% control %> block in a template - and then use to access individual fields on this object.

Find appropriate templates for SSViewer to use to render this object

When rendering some objects it is necessary to iterate over the object being rendered, to do this, you need access to itself.

Get part of the current classes ancestry to be used as a CSS class.

This method returns an escaped string of CSS classes representing the current classes ancestry until it hits a stop point - e.g. "Page DataObject ViewableData".

Return debug information about this object that can be rendered into a template

Get schema object

Destroy all of this objects dependent objects and local caches.

You'll need to call this to get the memory of an object that has components or extensions freed.

Create a duplicate of this node. Can duplicate many_many relations

Will default to cascade_duplicates if null. Set to 'false' to force none. Set to specific array of names to duplicate to override these. Note: If using versioned, this will additionally failover to owns config.

Copies the given relations from this object to the destination

Duplicates a single many_many relation from one object to another.

Duplicates a single many_many relation from one object to another.

Duplicates a single has_one relation from one object to another.

Note: Child object will be force written.

Duplicates a single belongs_to relation from one object to another.

Note: This will force a write on both parent / child objects.

Return obsolete class name, if this is no longer a valid class

Gets name of this class

Set the ClassName attribute. $class is also updated.

Warning: This will produce an inconsistent record, as the object instance will not automatically switch to the new subclass. Please use newClassInstance() for this purpose, or destroy and reinstanciate the record.

Create a new instance of a different class from this object's record.

This is useful when dynamically changing the type of an instance. Specifically, it ensures that the instance of the class is a match for the className of the record. Don't set the DataObject->class} or {@link DataObject->ClassName property manually before calling this method, as it will confuse change detection.

If the new class is different to the original class, defaults are populated again because this will only occur automatically on instantiation of a DataObject if there is no record, or the record has no ID. In this case, we do have an ID but we still need to repopulate the defaults.

Returns TRUE if all values (other than "ID") are considered empty (by weak boolean comparison).

Pluralise this item given a specific count.

E.g. "0 Pages", "1 File", "3 Images"

Get the user friendly singular name of this DataObject.

If the name is not defined (by redefining $singular_name in the subclass), this returns the class name.

Get the translated user friendly singular name of this DataObject same as singular_name() but runs it through the translating function

Translating string is in the form: $this->class.SINGULARNAME Example: Page.SINGULARNAME

Get the user friendly plural name of this DataObject If the name is not defined (by renaming $plural_name in the subclass), this returns a pluralised version of the class name.

Get the translated user friendly plural name of this DataObject Same as plural_name but runs it through the translation function Translation string is in the form: $this->class.PLURALNAME Example: Page.PLURALNAME

Get description for this class

Get localised description for this class

Standard implementation of a title/label for a specific record. Tries to find properties 'Title' or 'Name', and falls back to the 'ID'. Useful to provide user-friendly identification of a record, e.g. in errormessages or UI-selections.

Overload this method to have a more specialized implementation, e.g. for an Address record this could be:

function getTitle() {
  return "{$this->StreetNumber} {$this->StreetName} {$this->City}";
}

Returns the associated database record - in this case, the object itself.

This is included so that you can call $dataOrController->data() and get a DataObject all the time.

Convert this object to a map.

Note that it has the following quirks:

• custom getters, including those that adjust the result of database fields, won't be executed
• NULL values won't be returned.

Return all currently fetched database fields.

This function is similar to toMap() but doesn't trigger the lazy-loading of all unfetched fields. Obviously, this makes it a lot faster.

Update a number of fields on this object, given a map of the desired changes.

The field names can be simple names, or you can use a dot syntax to access $has_one relations. For example, array("Author.FirstName" => "Jim") will set $this->Author()->FirstName to "Jim".

Doesn't write the main object, but if you use the dot syntax, it will write() the related objects that it alters.

When using this method with user supplied data, it's very important to whitelist the allowed keys.

Pass changes as a map, and try to get automatic casting for these fields.

Doesn't write to the database. To write the data, use the write() method.

Merges data and relations from another object of same class, without conflict resolution. Allows to specify which dataset takes priority in case its not empty.

has_one-relations are just transferred with priority 'right'. has_many and many_many-relations are added regardless of priority.

Caution: has_many/many_many relations are moved rather than duplicated, meaning they are not connected to the merged object any longer. Caution: Just saves updated has_many/many_many relations to the database, doesn't write the updated object itself (just writes the object-properties). Caution: Does not delete the merged object. Caution: Does now overwrite Created date on the original object.

Forces the record to think that all its data has changed.

Doesn't write to the database. Force-change preserved until next write. Existing CHANGE_VALUE or CHANGE_STRICT values are preserved.

Validate the current object.

By default, there is no validation - objects are always valid! However, you can overload this method in your DataObject sub-classes to specify custom validation, or use the hook through DataExtension.

Invalid objects won't be able to be written - a warning will be thrown and no write will occur. onBeforeWrite() and onAfterWrite() won't get called either.

It is expected that you call validate() in your own application to test that an object is valid before attempting a write, and respond appropriately if it isn't.

Event handler called before writing to the database.

You can overload this to clean up or otherwise process data before writing it to the database. Don't forget to call parent::onBeforeWrite(), though!

This called after $this->validate(), so you can be sure that your data is valid.

Event handler called after writing to the database.

You can overload this to act upon changes made to the data after it is written. $this->changed will have a record database. Don't forget to call parent::onAfterWrite(), though!

Find all objects that will be cascade deleted if this object is deleted

Notes:

• If this object is versioned, objects will only be searched in the same stage as the given record.
• This will only be useful prior to deletion, as post-deletion this record will no longer exist.

Event handler called before deleting from the database.

You can overload this to clean up or otherwise process data before delete this record. Don't forget to call parent::onBeforeDelete(), though!

No description

Load the default values in from the DataObject::$defaults array.

Will traverse the defaults of the current class and all its parent classes. Called by the constructor when creating new records.

Determine validation of this object prior to write

Prepare an object prior to write

Detects and updates all changes made to this object

Writes a subset of changes for a specific table to the given manipulation

Ensures that a blank base record exists with the basic fixed fields for this dataobject

Does nothing if an ID is already assigned for this record

Generate and write the database manipulation for all changed fields

Writes all changes to this object to the database.

• It will insert a record whenever ID isn't set, otherwise update.
• All relevant tables will be updated.
• $this->onBeforeWrite() gets called beforehand.
• Extensions such as Versioned will amend the database-write to ensure that a version is saved.

Writes cached relation lists to the database, if possible

Write the cached components to the database. Cached components could refer to two different instances of the same record.

Delete this data object.

$this->onBeforeDelete() gets called. Note that in Versioned objects, both Stage and Live will be deleted.

Delete the record with the given ID.

Get the class ancestry, including the current class name.

The ancestry will be returned as an array of class names, where the 0th element will be the class that inherits directly from DataObject, and the last element will be the current class.

Return a unary component object from a one to one relationship, as a DataObject.

If no component is available, an 'empty component' will be returned for non-polymorphic relations, or for polymorphic relations with a class set.

Assign an item to the given component

No description

Returns a one-to-many relation as a HasManyList

Find the foreign class of a relation on this DataObject, regardless of the relation type.

Given a relation name, determine the relation type

Given a relation declared on a remote class, generate a substitute component for the opposite side of the relation.

Notes on behaviour:

• This can still be used on components that are defined on both sides, but do not need to be.
• All has_ones on remote class will be treated as local has_many, even if they are belongs_to
• Polymorphic relationships do not have two natural endpoints (only on one side) and thus attempting to infer them will return nothing.
• Cannot be used on unsaved objects.

Returns a many-to-many component, as a ManyManyList.

Return the class of a all has_one relations.

Returns the class of a remote belongs_to relationship. If no component is specified a map of all components and their class name will be returned.

Gets the class of a one-to-many relationship. If no $component is specified then an array of all the one-to-many relationships and their classes will be returned.

Return the many-to-many extra fields specification.

If you don't specify a component name, it returns all extra fields for all components available.

Return information about a many-to-many component.

The return value is an array of (parentclass, childclass). If $component is null, then all many-many components are returned.

This returns an array (if it exists) describing the database extensions that are required, or false if none

This is experimental, and is currently only a Postgres-specific enhancement.

Generates a SearchContext to be used for building and processing a generic search form for properties on this object.

Name of the field which is used as a stand-in for searching across all searchable fields.

If this is a blank string, general search functionality is disabled and the general search field falls back to using the first field in the searchable fields array.

Determine which properties on the DataObject are searchable, and map them to their default FormField representations. Used for scaffolding a searchform for ModelAdmin.

Some additional logic is included for switching field labels, based on how generic or specific the field type is.

Used by SearchContext.

Scaffold a simple edit form for all properties on this dataobject, based on default FormField} mapping in {@link DBField::scaffoldFormField().

Field labels/titles will be auto generated from DataObject::fieldLabels().

Scaffold a form field for selecting records of this model type in a has_one relation.

Scaffold a form field for selecting records of this model type in a has_many relation.

Scaffold a form field for selecting records of this model type in a many_many relation.

Allows user code to hook into DataObject::getCMSFields prior to updateCMSFields being called on extensions

Allows user code to hook into DataObject::getCMSFields after updateCMSFields being called on extensions

No description

need to be overload by solid dataobject, so that the customised actions of that dataobject, including that dataobject's extensions customised actions could be added to the EditForm.

When extending this class and overriding this method, you will need to instantiate the CompositeValidator by calling parent::getCMSCompositeValidator(). This will ensure that the appropriate extension point is also invoked.

You can also update the CompositeValidator by creating an Extension and implementing the updateCMSCompositeValidator(CompositeValidator $compositeValidator) method.

Used for simple frontend forms without relation editing or TabSet} behaviour. Uses {@link scaffoldFormFields() by default. To customize, either overload this method in your subclass, or extend it by DataExtension->updateFrontEndFields().

Loads all the stub fields that an initial lazy load didn't load fully.

Return the fields that have changed since the last write.

The change level affects what the functions defines as "changed":

• Level CHANGE_STRICT (integer 1) will return strict changes, even !== ones.
• Level CHANGE_VALUE (integer 2) is more lenient, it will only return real data changes, for example a change from 0 to null would not be included.

Example return:

array(
  'Title' = array('before' => 'Home', 'after' => 'Home-Changed', 'level' => DataObject::CHANGE_VALUE)
)
