Details

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()

Parameters

string $method
array $arguments

Return Value

mixed

Exceptions

BadMethodCallException

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().

protected registerExtraMethodCallback(string $name, callable $callback)

Register an callback to invoke that defines extra methods

Parameters

string $name
callable $callback

bool hasMethod(string $method)

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

Parameters

string $method

Return Value

bool

protected array getExtraMethodConfig(string $method)

Get meta-data details on a named method

Parameters

string $method

Return Value

array

List of custom method details, if defined for this method

array allMethodNames(bool $custom = false)

Return the names of all the methods available on this object

Parameters

bool $custom

include methods added dynamically at runtime

Return Value

array

protected array findMethodsFromExtension(object $extension) deprecated

deprecated 4.13.0 Will be replaced by findMethodsFrom() in CMS 5

No description

Parameters

object $extension

Return Value

array

protected addMethodsFrom(string $property, string|int $index = null)

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

Parameters

string $property

the property name

string|int $index

an index to use if the property is an array

Exceptions

InvalidArgumentException

protected removeMethodsFrom(string $property, string|int $index = null)

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

Parameters

string $property

the property name

string|int $index

an index to use if the property is an array

protected addWrapperMethod(string $method, string $wrap)

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)

Parameters

string $method

the method name to wrap

string $wrap

the method name to wrap to

protected addCallbackMethod(string $method, callable $callback)

Add callback as a method.

Parameters

string $method

Name of method

callable $callback

Callback to invoke. Note: $this is passed as first parameter to this callback and then $args as array

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.

Parameters

string $method

The name of the method to hook into

callable $callback

The callback to execute

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.

Parameters

string $method

The name of the method to hook into

callable $callback

The callback to execute

protected constructExtensions() deprecated

deprecated 4.0.0:5.0.0 Extensions and methods are now lazy-loaded

No description

protected 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()).

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')"

Return Value

bool

Flag if the extension was added

http://doc.silverstripe.org/framework/en/trunk/reference/dataextension

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.

Add support for removing extensions with parameters

Parameters

string $extension

class name of an Extension subclass, without parameters

static array get_extensions(string $class = null, bool $includeArgumentString = false)

No description

Parameters

string $class

If omitted, will get extensions for the current class

bool $includeArgumentString

Include the argument string in the return array, FALSE would return array("Versioned"), TRUE returns array("Versioned('Stage','Live')").

Return Value

array

Numeric array of either DataExtension class names, or eval'ed class name strings with constructor arguments.

static array|null get_extra_config_sources(string $class = null)

Get extra config sources for this class

Parameters

string $class

Name of class. If left null will return for the current class

Return Value

array|null

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))

Parameters

string $classOrExtension

Class to check extension for, or the extension name to check if the second argument is null.

string $requiredExtension

If the first argument is the parent class, this is the extension to check. If left null, the first parameter will be treated as the extension.

bool $strict

if the extension has to match the required extension and not be a subclass

Return Value

bool

Flag if the extension exists

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

Parameters

string $method

the method name to call

mixed $a1
mixed $a2
mixed $a3
mixed $a4
mixed $a5
mixed $a6
mixed $a7

Return Value

array

List of results with nulls filtered out

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

Return Value

array

Extension|null getExtensionInstance(string $extension)

Get an extension instance attached to this object by name.

Parameters

string $extension

Return Value

Extension|null

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()->hasExtension() as it will give you inconsistent results based on when the singleton was first accessed.

Parameters

string $extension

Classname of an Extension subclass without parameters

Return Value

bool

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.

Return Value

Extension[]

Map of DataExtension instances, keyed by classname.

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();

Parameters

mixed ...$args

Return Value

Injectable

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).

Parameters

string $class

Optional classname to create, if the called class should not be used

Return Value

Injectable

The singleton instance

static Config_ForClass config()

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

Return Value
