Examples of IUndoableOperation

org.eclipse.core.commands.operations.IUndoableOperation

IUndoableOperation defines an operation that can be executed, undone, and redone. Operations typically have fully defined parameters. That is, they are usually created after the user has been queried for any input needed to define the operation.

Operations determine their ability to execute, undo, or redo according to the current state of the application. They do not make decisions about their validity based on where they occur in the operation history. That is left to the particular operation history.
