AdvancedValidationUserApprover.java | Class |
An operation approver that rechecks the validity of a proposed undo or redo
operation using
IAdvancedUndoableOperation.computeUndoableStatus(IProgressMonitor) or
IAdvancedUndoableOperation.computeRedoableStatus(IProgressMonitor) .
Some complex operations do not compute their validity in canUndo() or
canRedo() because it is too time-consuming. |
