create(array ...$args)

Creates a class instance by the "singleton" design pattern.

__construct()

static mixed
get(array $context)

Get the value out of the graphql context array

array
provideContext()

Should return key/value pairs that will merge into a separate query context

Details

static Injectable create(array ...$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'); $list = SiteTree::get();

Parameters

array ...$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()

QueryStateProvider constructor.

static mixed get(array $context)

Get the value out of the graphql context array

Parameters

array $context

Return Value

mixed

array provideContext()

Should return key/value pairs that will merge into a separate query context

Return Value

array
