IAdvancedUndoableOperation defines an interface for undoable operations that modify one or more elements in a model and attempt to keep model listeners up to date with changes that occur in the undo and redo history involving particular model elements.
IAdvancedUndoableOperation2 defines a method for computing the validity of executing an operation before attempting to execute it.
ICompositeOperation defines an undoable operation that is composed of child operations.
IContextReplacingOperation defines an interface for undoable operations that can replace one undo context with another undo context.
IOperationApprover defines an interface for approving the undo or redo of a particular operation within an operation history.
IOperationHistory tracks a history of operations that can be undone or redone.
This interface is used to listen to notifications from an IOperationHistory.
IUndoableOperation defines an operation that can be executed, undone, and redone.
An undo context is used to "tag" operations as being applicable to a certain context.
Abstract implementation for an undoable operation.
A base implementation of IOperationHistory that implements a linear undo and redo model .
An operation approver that enforces a strict linear undo.
An abstract class for detecting violations in a strict linear undo/redo model.
An undo context that can be used to represent any given object.
OperationHistoryEvent is used to communicate changes that occur in a DefaultOperationHistory, including the addition or removal of operations, and the execution, undo, and redo of operations.
This class is used to maintain the instance of the operation history that should be used by classes that access the undo or redo history and add undoable operations to the history.
OperationStatus describes the status of a request to execute, undo, or redo an operation.
Triggered operations are a specialized implementation of a composite operation that keeps track of operations triggered by the execution of some primary operation.
A simple, lightweight undo context that can be used to tag any operation.
