Detailed Description

Content handler implementation for unknown content.

This can be used to handle content for which no ContentHandler exists on the system, perhaps because the extension that provided it has been removed.

Definition at line 34 of file UnknownContentHandler.php.

Constructor & Destructor Documentation

◆ __construct()

UnknownContentHandler::__construct	(		$modelId,
			$formats = null )

Constructs an UnknownContentHandler.

Since UnknownContentHandler can be registered for multiple model IDs on a system, multiple instances of UnknownContentHandler may coexist.

To preserve the serialization format of the original content model, it must be supplied to the constructor via the $formats parameter. If not given, the default format is reported as 'application/octet-stream'.

Parameters

string	$modelId
string[] \| null	$formats

Reimplemented from ContentHandler.

Definition at line 48 of file UnknownContentHandler.php.

Member Function Documentation

◆ getSlotDiffRendererInternal()

UnknownContentHandler::getSlotDiffRendererInternal ( IContextSource $context )

protected

Parameters

IContextSource $context

Returns: SlotDiffRenderer

Reimplemented from ContentHandler.

Definition at line 112 of file UnknownContentHandler.php.

References $context.

◆ makeEmptyContent()

UnknownContentHandler::makeEmptyContent ( )

Creates an empty UnknownContent object.

Since: 1.21

Returns: Content A new UnknownContent object with empty text.

Reimplemented from ContentHandler.

◆ serializeContent()

UnknownContentHandler::serializeContent	(	Content	$content,
			$format = null )

Returns the content's data as-is.

Parameters

◆ unserializeContent()

UnknownContentHandler::unserializeContent	(		$blob,
			$format = null )

Constructs an UnknownContent instance wrapping the given data.

Since: 1.21

Parameters

string	$blob	serialized content in an unknown format
string \| null	$format	ignored

Returns: Content The UnknownContent object wrapping $data

Reimplemented from ContentHandler.
