Example 1 with DocumentRewriteSession

use of org.eclipse.jface.text.DocumentRewriteSession in project che by eclipse.

the class TextChange method performEdits.

/**
	 * Executes the text edits on the given document.
	 * Subclasses that override this method should call <code>super.performEdits(document)</code>.
	 * 
	 * @param document the document
	 * @return an object representing the undo of the executed edits
	 * @exception MalformedTreeException is thrown if the edit tree isn't
	 *  in a valid state. This exception is thrown before any edit is executed.
	 *  So the document is still in its original state.
	 * @exception BadLocationException is thrown if one of the edits in the
	 *  tree can't be executed. The state of the document is undefined if this
	 *  exception is thrown.
	 * @since 3.5
