Examples of IRewriteTarget

at.bestsolution.efxclipse.text.jface.IRewriteTarget
A target publishing the required functions to modify a document that is displayed in a text viewer. It provides access to the document and control over the redraw behavior and the grouping of document changes into undo commands. @see org.eclipse.jface.text.ITextViewer @see org.eclipse.jface.text.IDocument @see org.eclipse.jface.text.IUndoManager @since 2.0
