Details

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

array getURLHandlers(GridField $gridField)

Parameters

GridField $gridField

Return Value

array

setThrowExceptionOnBadDataType(bool $throwExceptionOnBadDataType) deprecated

deprecated 5.2.0 Will be removed without equivalent functionality

Determine what happens when this component is used with a list that isn't SS_Filterable.

  • true: An exception is thrown
    • false: This component will be ignored - it won't make any changes to the GridField.

By default, this is set to true so that it's clearer what's happening, but the predefined GridFieldConfig subclasses set this to false for flexibility.

Parameters

bool $throwExceptionOnBadDataType

getThrowExceptionOnBadDataType() deprecated

deprecated 5.2.0 Will be removed without equivalent functionality
