Method Detail

isMoveInsertion

public static boolean isMoveInsertion(DocumentEvent e)

Moving a text fragment using DocumentEx.moveText(int, int, int) is accomplished by a combination of insertion and deletion. This method tells whether the event notifies about an insertion that, together with a subsequent deletion, makes up the text movement. A move insertion event is also the one during which all range markers contained in the text fragment being moved are evacuated to their destination.

isMoveDeletion

public static boolean isMoveDeletion(DocumentEvent e)

Tells whether the event notifies about a deletion that, together with a preceding insertion, makes up a text movement.
