public static 
array
get_template_global_variables()

Called by SSViewer to get a list of global variables to expose to the template, the static method to call on this class to get the value for those variables, and the class to use for casting the returned value for use in a template

Details

static Config_ForClass config()

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

Return Value

Config_ForClass

mixed stat(string $name) deprecated

deprecated 5.0 Use ->config()->get() instead

Get inherited config value

Parameters

string $name

Return Value

mixed

mixed uninherited(string $name)

Gets the uninherited value for the given config option

Parameters

string $name

Return Value

mixed

$this set_stat(string $name, mixed $value) deprecated

deprecated 5.0 Use ->config()->set() instead

Update the config value for a given property

Parameters

string $name
mixed $value

Return Value

$this

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

__construct(string $name = null)

Parameters

string $name

static SecurityToken inst()

Return Value

SecurityToken

static disable()

Globally disable the token (override with NullSecurityToken) implementation. Note: Does not apply for

static enable()

Globally enable tokens that have been previously disabled through disable.

Return Value

string

static array get_template_global_variables()

Called by SSViewer to get a list of global variables to expose to the template, the static method to call on this class to get the value for those variables, and the class to use for casting the returned value for use in a template

If the method to call is not included for a particular template variable, a method named the same as the template variable will be called

If the casting class is not specified for a particular template variable, ViewableData::$default_cast is used

The first letter of the template variable is case-insensitive. However the method name is always case sensitive.

Return Value

array

Returns an array of items. Each key => value pair is one of three forms:

  • template name (no key)
  • template name => method name
  • template name => [], where the array can contain these key => value pairs
    • "method" => method name
    • "casting" => casting class to use (i.e., Varchar, HTMLFragment, etc)
