```
public interface ITextOperationTarget
```
Defines the target for text operations. canDoOperation informs the clients about the ability of the target to perform the specified operation at the current point in time. doOperation executes the specified operation.
In order to provide backward compatibility for clients of ITextOperationTarget, extension interfaces are used as a means of evolution. The following extension interfaces exist:
- ITextOperationTargetExtension since version 2.0 introducing text operation enabling/disabling.
