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
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.
Get all extension instances for this specific object instance.
An implementation of the factory method, allows you to create an instance of a class
Creates a class instance by the "singleton" design pattern.

Gets the uninherited value for the given config option
Check if a field exists on this object or its failover.
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.

Return true if this object "exists" i.e. has a sensible value
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:

- an SSViewer instance
Generate the cache name for a field
Store a value in the field 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.
Checks if a given method/field has a valid value. If the result is an object, this will return the result of the exists method, otherwise will check if the result is not just an empty paragraph tag.
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.

Throws a HTTP error response encased in a HTTPResponse_Exception, which is later caught in RequestHandler::handleAction() and returned to the user.
Returns the HTTPRequest object that this controller is using.
Typically the request is set through handleAction() or handleRequest(), but in some based we want to set it manually.
Returns a link to this controller. Overload with your own Link rules if they exist.
Safely get the value of the BackURL param, if provided via querystring / posted var
Redirect back. Uses either the HTTP-Referer or a manually set request-variable called "BackURL".
Sets extra sort fields to apply before the sort field.
Sets the number of the column containing the reorder handles.
Return URLs to be handled by this grid field, in an array the same form as $url_handlers.

mixed
__call(string $method, array $arguments)
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()
protected
defineMethods()
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().

This should be used rather than PHP's inbuild method_exists() as it takes into account methods added via extensions
protected array
getExtraMethodConfig(string $method)
Get meta-data details on a named method

defineExtensionMethods()
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().
static bool
add_extension(string $classOrExtension, string $extension = null)
Add an extension to a specific class.
The preferred method for adding extensions is through YAML config, since it avoids autoloading the class, and is easier to override in more specific configurations.
As an alternative, extensions can be added to a specific class directly in the Object::$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()).
static
remove_extension(string $extension)
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.
static array
get_extensions(string $class = null, bool $includeArgumentString = false)
No description
static array|null
get_extra_config_sources(string $class = null)
Get extra config sources for this class
static bool
has_extension(string $classOrExtension, string $requiredExtension = null, bool $strict = false)
Return TRUE if a class has a specified extension.
This supports backwards-compatible format (static Object::has_extension($requiredExtension)) and new format ($object->has_extension($class, $requiredExtension))
array
invokeWithExtensions(string $method, mixed $a1 = null, mixed $a2 = null, mixed $a3 = null, mixed $a4 = null, mixed $a5 = null, mixed $a6 = null, mixed $a7 = null)
Calls a method if available on both this object and all applied Extensions, and then attempts to merge all results into an array
array
extend(string $method, mixed $a1 = null, mixed $a2 = null, mixed $a3 = null, mixed $a4 = null, mixed $a5 = null, mixed $a6 = null, mixed $a7 = null)
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().
Extension|null
getExtensionInstance(string $extension)
Get an extension instance attached to this object by name.
bool
hasExtension(string $extension)
Returns TRUE if this object instance has a specific extension applied in $extension_instances. Extension instances are initialized at constructor time, meaning if you use add_extension() afterwards, the added extension will just be added to new instances of the extended class. Use the static method has_extension() to check if a class (not an instance) has a specific extension.
Caution: Don't use singleton(
Extension[]
getExtensionInstances()
Get all extension instances for this specific object instance.
See get_extensions() to get all applied extension classes for this class (not the instance).
This method also provides lazy-population of the extension_instances property.
static Injectable
create(mixed ...$args)
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();
static Injectable
singleton(string $class = null)
Creates a class instance by the "singleton" design pattern.
It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).
static Config_ForClass
config()
Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
mixed
stat(string $name)
deprecated

Note that, unlike the core isset() implementation, this will return true if the property is defined and set to null.
mixed
__get(string $property)
Get the value of a property/field on this object. This will check if a method called get{$property} exists, then check if a field is available using ViewableData::getField(), then fall back on a failover object.
__set(string $property, mixed $value)
Set a property/field on this object. This will check for the existence of a method called set{$property}, then use the ViewableData::setField() method.

ViewableData|null
getFailover()
Get the current failover object if set

$this
setField(string $field, mixed $value)
Set a field on this object. This should be overloaded in child classes.
ViewableData_Customised
customise(array|ViewableData $data)
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.
bool
exists()
Return true if this object "exists" i.e. has a sensible value
This method should be overridden in subclasses to provide more context about the classes state. For example, a DataObject class could return false when it is deleted from the database

Get the value of a field on this object, automatically inserting the value into any available casting objects that have been specified.
object|DBField
cachedCall(string $field, array $arguments = [], string $identifier = null)
A simple wrapper around ViewableData::obj() that automatically caches the result so it can be used again without re-running the method.
bool
hasValue(string $field, array $arguments = [], bool $cache = true)
Checks if a given method/field has a valid value. If the result is an object, this will return the result of the exists method, otherwise will check if the result is not just an empty paragraph tag.
string

Get the string value of a field on this object that has been suitable escaped to be inserted directly into a template.
array
getXMLValues(array $fields)
Get an array of XML-escaped values by field name
ArrayIterator
getIterator()
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.
array
getViewerTemplates(string $suffix = '')
Find appropriate templates for SSViewer to use to render this object
ViewableData
Me()
When rendering some objects it is necessary to iterate over the object being rendered, to do this, you need access to itself.
string
ThemeDir()
deprecated
deprecated
Return the directory if the current active theme (relative to the site root).
This method is useful for things such as accessing theme images from your template without hardcoding the theme
page - e.g. 
.
This method should only be used when a theme is currently active. However, it will fall over to the current project directory.
string
CSSClasses(string $stopAtClass = self::class)
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".
ViewableData_Debugger
Debug()
Return debug information about this object that can be rendered into a template
HTTPResponse|RequestHandler|string|array
handleRequest(HTTPRequest $request)
Handles URL requests.
- ViewableData::handleRequest() iterates through each rule in self::$url_handlers.
- If the rule matches, the named method will be called.
- If there is still more URL to be processed, then handleRequest() is called on the object that that method returns.
Once all of the URL has been processed, the final result is returned. However, if the final result is an array, this array is interpreted as being additional template data to customise the 2nd to last result with, rather than an object in its own right. This is most frequently used when a Controller's action will return an array of data with which to customise the controller.

allowedActions(string $limitToClass = null)
Get a array of allowed actions defined on this controller, any parent classes or extensions.
Caution: Since 3.1, allowed_actions definitions only apply to methods on the controller they're defined on, so it is recommended to use the $class argument when invoking this method.
bool
hasAction(string $action)
Checks if this request handler has a specific action, even if the current user cannot access it.
Includes class ancestry and extensions in the checks.
protected string
definingClassForAction(string $actionOrigCasing)
Return the class that defines the given action, so that we know where to check allowed_actions.
bool
checkAccessAction(string $action)
Check that the given action is allowed to be called from a URL.
It will interrogate self::$allowed_actions to determine this.
httpError(int $errorCode, string $errorMessage = null)
Throws a HTTP error response encased in a HTTPResponse_Exception, which is later caught in RequestHandler::handleAction() and returned to the user.
HTTPRequest
getRequest()
Returns the HTTPRequest object that this controller is using.
Returns a placeholder NullHTTPRequest object unless handleAction()} or {@link handleRequest() have been called, which adds a reference to an actual HTTPRequest object.
