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

static Config_ForClass config()

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

Return Value

Config_ForClass

mixed uninherited(string $name)

Gets the uninherited value for the given config option

Parameters

string $name

Return Value

mixed

__construct(int $itemsPerPage = null)

No description

Parameters

int $itemsPerPage
  • How many items should be displayed per page

$this 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

Return Value

$this

bool getThrowExceptionOnBadDataType() deprecated

deprecated 5.2.0 Will be removed without equivalent functionality

See setThrowExceptionOnBadDataType()

Return Value

bool

protected bool checkDataType(SS_List $dataList)

Check that this dataList is of the right data type.

Returns false if it's a bad data type, and if appropriate, throws an exception.

Parameters

SS_List $dataList

Return Value

bool

array getActions(GridField $gridField)
