Methods

	Name	Description
	Add	Pushes the specified undo unit onto the undo stack.
	AddOrMerge	Adds an undo unit to the undo stack, potentially merging it with other undo units on the stack or dropping it if it is empty. If it has UndoOption.AddForce, it will always be added, even if it is empty. This is useful for compound operations such as moving nodes, drag/drop or label editing where you merge a series of undo units into one atomic unit and you must have a sure way of starting with the Add unit even if it is at first empty.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
