static Config_ForClass|null config()

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

....).

Return Value

Config_ForClass|null

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 {@link 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().

Returns a 2-elemnent array, with classname and arguments

Parameters

$classSpec

in SS_Object at line 341
static SS_Object strong_create()

Return Value

SS_Object

in SS_Object at line 361
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 {@link Object::create()}

Parameters

string $oldClass the class to replace
string $newClass the class to replace it with
bool $strong allows you to enforce a certain class replacement under all circumstances. This is used in singletons and DB interaction classes

in SS_Object at line 375
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

Parameters

string $class the class to check

Return Value

string the class that would be created if you called {@link Object::create()} with the class

in SS_Object at line 396
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.

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, boolean $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
boolean $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 {@link Object::$extensions} array. See {@link SiteTree::$extensions} for examples. Keep in mind that the extension will only be applied to new instances, not existing ones (including all instances created through {@link singleton()}).

Parameters

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

See also

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

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 {@link Object} instances which are already created, but will have an effect on new extensions. Clears any previously created singletons through {@link singleton()} to avoid side-effects from stale extension information.

Parameters

string $extension Classname of an {@link Extension} subclass, without parameters

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

Parameters

string $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 {@link DataExtension} classnames, or eval'ed classname strings with constructor arguments.

mixed invokeWithExtensions(string $method, mixed $argument = null)

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

Parameters

string $method the method name to call
mixed $argument a single argument to pass

Return Value

mixed

in SS_Object at line 1058
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 {@link __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 getExtensionInstance(string $extension)

Get an extension instance attached to this object by name.

Parameters

string $extension

Return Value

in SS_Object at line 1115
bool hasExtension(string $extension)

Returns TRUE if this object instance has a specific extension applied in {@link $extension_instances}. Extension instances are initialized at constructor time, meaning if you use {@link add_extension()} afterwards, the added extension will just be added to new instances of the extended class. Use the static method {@link 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.
