◆ 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$oldOld content
Content$newNew content
Exceptions
MWExceptionIf old or new content is not an instance of TextContent.
Returns
bool|string

)

Generate a diff, no caching.

Todo:

Parameters

string$ntextNew text, must be already segmented
