Detailed Description

Renders a slot diff by doing a text diff on the native representation.

If you want to use this without content objects (to call getTextDiff() on some non-content-related texts), obtain an instance with ContentHandler::getForModelID( CONTENT_MODEL_TEXT ) ->getSlotDiffRenderer( RequestContext::getMain() )

Member Function Documentation

◆ diff()

static TextSlotDiffRenderer::diff	(		$oldText,
			$newText )

static

Convenience helper to use getTextDiff without an instance.

Parameters

string	$oldText
string	$newText

Returns: string

Definition at line 74 of file TextSlotDiffRenderer.php.

References CONTENT_MODEL_TEXT.

◆ getDiff()

TextSlotDiffRenderer::getDiff	(	Content	$oldContent = null,
		Content	$newContent = null )

@inheritDoc

Reimplemented from SlotDiffRenderer.

Definition at line 119 of file TextSlotDiffRenderer.php.

References getTextDiff(), and SlotDiffRenderer\normalizeContents().

◆ getTextDiff()

TextSlotDiffRenderer::getTextDiff	(		$oldText,
			$newText )

Diff the text representations of two content objects (or just two pieces of text in general).

Parameters

string	$oldText
string	$newText

Returns: string

◆ getTextDiffInternal()

TextSlotDiffRenderer::getTextDiffInternal	(		$oldText,
			$newText )

protected

Diff the text representations of two content objects (or just two pieces of text in general).

This does the actual diffing, getTextDiff() wraps it with logging and resource limiting.

Parameters

string	$oldText
string	$newText

Returns: string
