◆ deletedLink()

DifferenceEngine::deletedLink ( $id )

◆ generateContentDiffBody()

DifferenceEngine::generateContentDiffBody	(	Content	$old,
		Content	$new )

Generate a diff, no caching.

This implementation uses generateTextDiffBody() to generate a diff based on the default serialization of the given Content objects. This will fail if $old or $new are not instances of TextContent.

Subclasses may override this to provide a different rendering for the diff, perhaps taking advantage of the content's native form. This is required for all content models that are not text based.

Since: 1.21

Parameters

Content	$old	Old content
Content	$new	New content

Exceptions

MWException If old or new content is not an instance of TextContent.

Returns: bool|string

Todo: move this to TextDifferenceEngine, make DifferenceEngine abstract. At some point.

Parameters
