Methods
Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
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.
An implementation of the factory method, allows you to create an instance of a class
Creates a class instance by the "singleton" design pattern.
Create an object from a string representation. It treats it as a PHP constructor without the 'new' keyword. It also manages to construct the object without the use of eval().
Parses a class-spec, such as "Versioned('Stage','Live')", as passed to create_from_string().
Similar to Object::create(), except that classes are only overloaded if you set the $strong parameter to TRUE when using Object::useCustomClass()
This class allows you to overload classes with other classes when they are constructed using the factory method Object::create()
If a class has been overloaded, get the class name it has been overloaded with - otherwise return the class name
Get the value of a static property of a class, even in that property is declared protected (but not private), without any inheritance, merging or parent lookup if it doesn't exist on the given class.
Return TRUE if a class has a specified extension.
Add an extension to a specific class.
No description

Return the names of all the methods available on this object
Add methods from the ViewableData::$failover object, as well as wrapping any methods prefixed with an underscore into a ViewableData::cachedCall().
Add all the methods from an object property (which is an Extension) to this object.
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 an extra method using raw PHP code passed as a string
Check if this class is an instance of a specific class, or has that class as one of its parents
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
Get an extension instance attached to this object by name.
Returns TRUE if this object instance has a specific extension applied in $extension_instances. Extension instances are initialized at constructor time, meaning if you use add_extension() afterwards, the added extension will just be added to new instances of the extended class. Use the static method has_extension() to check if a class (not an instance) has a specific extension.
Get all extension instances for this specific object instance.
Cache the results of an instance method in this object to a file, or if it is already cache return the cached results
Clears the cache for the given cacheToFile call
Loads a cache from the filesystem if a valid on is present and within the specified lifetime
Save a piece of cached data to the file system
Strip a file name of special characters so it is suitable for use as a cache file name
Converts a field spec into an object creator. For example: "Int" becomes "new Int($fieldName);" and "Varchar(50)" becomes "new Varchar($fieldName, 50);".
Convert a field schema (e.g. "Varchar(50)") into a casting object creator array that contains both a className and castingHelper constructor code. See castingObjectCreator for more information about the constructor.
Check if a field exists on this object or its failover.
Get the value of a property/field on this object. This will check if a method called get{$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.
Set a failover object to attempt to get data from if it is not present on this object.
Check if a field exists on this object. This should be overloaded in child classes.
Get the value of a field on this object. This should be overloaded in child classes.
Set a field on this object. This should be overloaded in child classes.

Get the class a field on this object would be casted to, as well as the casting helper for casting a field to an object (see ViewableData::castingHelper() for information on casting helpers).
Return the "casting helper" (a piece of PHP code that when evaluated creates a casted value object) for a field on this object.
Get the class name a field on this object will be casted to
Return the string-format type for the given field.
Save the casting cache for this object (including data from any failovers) into a variable

- an SSViewer instance
Generate the cache name for a field
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.
Return the value of the field without any escaping being applied.
Return the value of a field in an SQL-safe format.
Return the value of a field in a JavaScript-save format.
Return the value of a field escaped suitable to be inserted into an XML node attribute.
Get an array of XML-escaped values by field name
When rendering some objects it is necessary to iterate over the object being rendered, to do this, you need access to itself.
Return the directory if the current active theme (relative to the site root).

Details
static Config_ForClass|null
config()
Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
protected
beforeExtending(string $method, callable $callback)
Allows user code to hook into Object::extend prior to control being delegated to extensions. Each callback will be reset once called.
protected
afterExtending(string $method, callable $callback)
Allows user code to hook into Object::extend after control being delegated to extensions. Each callback will be reset once called.
static SS_Object
create()
An implementation of the factory method, allows you to create an instance of a class
This method first for strong class overloads (singletons & DB interaction), then custom class overloads. If an overload is found, an instance of this is returned rather than the original class. To overload a class, use Object::useCustomClass()
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'); $list = SiteTree::get();
static SS_Object
singleton()
Creates a class instance by the "singleton" design pattern.
It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).
static
create_from_string($classSpec, $firstArg = null)
Create an object from a string representation. It treats it as a PHP constructor without the 'new' keyword. It also manages to construct the object without the use of eval().
Construction itself is done with Object::create(), so that Object::useCustomClass() calls are respected.
Object::create_from_string("Versioned('Stage','Live')") will return the result of
Versioned::create('Stage', 'Live);
It is designed for simple, clonable objects. The first time this method is called for a given string it is cached, and clones of that object are returned.
If you pass the $firstArg argument, this will be prepended to the constructor arguments. It's impossible to pass null as the firstArg argument.
Object::create_from_string("Varchar(50)", "MyField") will return the result of
Vachar::create('MyField', '50');
Arguments are always strings, although this is a quirk of the current implementation rather than something that can be relied upon.
static
parse_class_spec($classSpec)
Parses a class-spec, such as "Versioned('Stage','Live')", as passed to create_from_string().
Returns a 2-elemnent array, with classname and arguments
static SS_Object
strong_create()
Similar to Object::create(), except that classes are only overloaded if you set the $strong parameter to TRUE when using Object::useCustomClass()
static
useCustomClass(string $oldClass, string $newClass, bool $strong = false)
This class allows you to overload classes with other classes when they are constructed using the factory method Object::create()
static string
getCustomClass(string $class)
If a class has been overloaded, get the class name it has been overloaded with - otherwise return the class name
static any
static_lookup($class, $name, null $default = null)
Get the value of a static property of a class, even in that property is declared protected (but not private), without any inheritance, merging or parent lookup if it doesn't exist on the given class.

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))
static
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.
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.

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
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.

FieldList
makeReadonly()
Transforms this FieldList instance to readonly.
makeFieldReadonly($field)
Transform the named field into a readonly feld.
changeFieldOrder(array $fieldNames)
Change the order of fields in this FieldList by specifying an ordered list of field names.
This works well in conjunction with SilverStripe's scaffolding functions: take the scaffold, and shuffle the fields around to the order that you want.
Please note that any tabs or other dataless fields will be clobbered by this operation.
int
fieldPosition($field)
Find the numerical position of a field within the children collection. Doesn't work recursively.
setTabPathRewrites(array $rewrites)
Ordered list of regular expressions matching a tab path, to their rewrite rule (through preg_replace()).
Mainly used for backwards compatibility. Ensure that more specific rules are placed earlier in the list, and that tabs with children are accounted for in the rule sets.
Example: $fields->setTabPathRewriting(array( // Rewrite specific innermost tab '/^Root.Content.Main$/' => 'Root.Content', // Rewrite all innermost tabs '/^Root.Content.([^.]+)$/' => 'Root.\1', ));
array
getTabPathRewrites()
No description
protected string
rewriteTabPath(string $name)
Support function for backwards compatibility purposes.
Caution: Volatile API, might be removed in 3.1 or later.
forTemplate()
Default template rendering of a FieldList will concatenate all FieldHolder values.
