Operations are transformations of a text flow. An Operation class defines the logic for performing and undoing the transformation. Operations are executed by an edit manager. Most applications do not need to create or manage operations directly (unless implementing a custom edit manager).
When an operation is performed, the edit manager dispatches an Operation object within the FlowOperationEvent object. You can query this Operation object to decide whether or not to allow the operation, to decide whether to perform some other operation as well, or to update related user-interface elements.

FlowOperation | () | Constructor |
public function FlowOperation(textFlow:flashx.textLayout.elements:TextFlow)| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Creates the FlowOperation object.
ParameterstextFlow:flashx.textLayout.elements:TextFlow — The text flow to which this operation is applied.

canUndo | () | method |
doOperation | () | method |
public function doOperation():Boolean| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Executes the operation.
This method must be overridden in derived classes. The base class method does nothing.
You should not call doOperation() directly. The edit manager
calls the method when it executes the operation.
Boolean — Boolean true, if the operation succeeded. Otherwise, false.
|
redo | () | method |
public function redo():SelectionState| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Re-executes the operation.
This method must be overridden in derived classes. The base class method does nothing.
You should not call redo() directly. The edit manager
calls the method when it re-executes the operation.
SelectionState — The SelectionState object passed to the operation when it was performed. This
SelectionState object can be the current selection or a selection created specifically
for the operation.
|
undo | () | method |
public function undo():SelectionState| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Reverses the operation.
This method must be overridden in derived classes. The base class method does nothing.
You should not call undo() directly. The edit manager
calls the method when it reverses the operation.
SelectionState — The SelectionState object passed to the operation when it was performed. This
SelectionState object can be the current selection or a selection created specifically
for the operation.
