Class UndoQueue

java.lang.Object
com.oorian.html.elements.UndoQueue
public class UndoQueue extends Object
A fixed-size undo queue that stores string values for undo operations.

UndoQueue maintains a bounded queue of string values, automatically discarding the oldest entries when the maximum size is exceeded. This is useful for implementing undo functionality where only a limited number of previous states need to be retained.
