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

__construct(resource $stream, int $contentLength, int $statusCode = null, string $statusDescription = null)

HTTPStreamResponse constructor.

Parameters

resource $stream

Data stream

int $contentLength

size of the stream in bytes

int $statusCode

The numeric status code - 200, 404, etc

string $statusDescription

The text to be given alongside the status code. See setStatusCode() for more information.

$this setProtocolVersion(string $protocolVersion)

The HTTP version used to respond to this request (typically 1.0 or 1.1)

Parameters

string $protocolVersion

Return Value

$this

$this setStatusCode(int $code, string $description = null)

No description

Parameters

int $code
string $description

Optional. See setStatusDescription(). No newlines are allowed in the description. If omitted, will default to the standard HTTP description for the given $code value (see $status_codes).

Return Value

$this

$this setStatusDescription(string $description)

The text to be given alongside the status code ("reason phrase").

Caution: Will be overwritten by setStatusCode().

Parameters
