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 37 of file FallbackContentHandler.php.

Constructor & Destructor Documentation

◆ __construct()

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

Constructs an FallbackContentHandler.

Since FallbackContentHandler can be registered for multiple model IDs on a system, multiple instances of FallbackContentHandler 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 51 of file FallbackContentHandler.php.

Member Function Documentation

◆ fillParserOutput()

FallbackContentHandler::fillParserOutput	(	Content	$content,
		ContentParseParams	$cpoParams,
		ParserOutput &	$output )

protected

Fills the ParserOutput with an error message.

Since: 1.38

Parameters

Content	$content
ContentParseParams	$cpoParams
ParserOutput	&$output	The output object to fill (reference).

Reimplemented from ContentHandler.

Definition at line 118 of file FallbackContentHandler.php.

◆ getSlotDiffRendererInternal()

FallbackContentHandler::getSlotDiffRendererInternal ( IContextSource $context )

protected

Parameters

IContextSource $context

Returns: SlotDiffRenderer

Reimplemented from ContentHandler.

Definition at line 134 of file FallbackContentHandler.php.

◆ makeEmptyContent()

FallbackContentHandler::makeEmptyContent ( )

Creates an empty FallbackContent object.

Since: 1.21

Returns: Content A new FallbackContent object with empty text.

Reimplemented from ContentHandler.

Definition at line 99 of file FallbackContentHandler.php.

References unserializeContent().

◆ serializeContent()

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

Returns the content's data as-is.

Parameters

Content	$content
string \| null	$format	The serialization format to check

Returns: mixed

Returns: false

Reimplemented from ContentHandler.

Definition at line 106 of file FallbackContentHandler.php.

◆ unserializeContent()

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

Constructs an FallbackContent instance wrapping the given data.

Since: 1.21

Parameters

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

Returns: Content The FallbackContent object wrapping $data

Reimplemented from ContentHandler.
