in SS_Object at line 132
`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();

Return Value

SS_Object

in SS_Object at line 155
`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).

Return Value

SS_Object

The singleton instance

in SS_Object at line 190
`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.

Parameters

	$classSpec
	$firstArg

in SS_Object at line 215
`static parse_class_spec($classSpec)`

Parses a class-spec, such as "Versioned('Stage','Live')", as passed to create_from_string().

string

the class that would be created if you called Object::create() with the class

`static any static_lookup($class, $name, null $default = null)`

Parameters

	$class	The class to get the static from
	$name	The property to get from the class
null	$default	The value to return if property doesn't exist on class

Return Value

any	The value of the static property $name on class $class, or $default if that property is not defined

`static 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))

Parameters

string	$classOrExtension	if 1 argument supplied, the class name of the extension to check for; if 2 supplied, the class name to test
string	$requiredExtension	used only if 2 arguments supplied
bool	$strict	if the extension has to match the required extension and not be a subclass

in SS_Object at line 536
`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()).

Parameters

string	$classOrExtension	Class that should be extended - has to be a subclass of Object
string	$extension	Subclass of Extension with optional parameters as a string, e.g. "Versioned" or "Translatable('Param')"

in SS_Object at line 594
`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.

Add support for removing extensions with parameters

Parameters

string

$extension

Classname of an Extension subclass, without parameters

in SS_Object at line 633
`static array get_extensions(string $class, bool $includeArgumentString = false)`

Numeric array of either DataExtension classnames, or eval'ed classname strings with constructor arguments.

`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().

Parameters

string	$method	the name of the method to call on each extension
mixed	$a1
mixed	$a2
mixed	$a3
mixed	$a4
mixed	$a5
mixed	$a6
mixed	$a7
