Examples of org.eclipse.text.edits.TextEdit.apply()

org.eclipse.text.edits.TextEdit.apply()
Applies the edit tree rooted by this edit to the given document. To check if the edit tree can be applied to the document either catch MalformedTreeException or use TextEditProcessor to execute an edit tree. @param document the document to be manipulated @param style flags controlling the execution of the edit tree. Validflags are: CREATE_UNDO and UPDATE_REGIONS. @return a undo edit, if CREATE_UNDO is specified. Otherwisenull is returned. @exception MalformedTreeException is thrown if the tree isn'tin 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 editsin the tree can't be executed. The state of the document is undefined if this exception is thrown. @see TextEditProcessor#performEdits()

      Document document = new Document(this.document.get());
