- All Implemented Interfaces:
- EditPolicy, RequestConstants
- public abstract class ConnectionEditPolicy
- extends AbstractEditPolicy
A model-based EditPolicy for connections. A model-based EditPolicy only knows about
the host's model and the basic operations it supports. By default, ConnectionEditPolicy
understands only DELETE. Subclasses can add support to handle additional behavior
specific to the model.
This EditPolicy is not a GraphicalEditPolicy
, and
should not be used to show feedback or interact with the host's visuals in any way.
- Since:
- 2.0
