You can execute a command in the canonical policy. I do something similar
to correct copy pasted connections. Execute a command whenever a certain
event occurs, see code below.
vlad
public class B2CanonicalConnectionEditPolicy extends
CanonicalConnectionEditPolicy {
private static class FixCopyPastedConnectionsCommand extends
AbstractTransactionalCommand {
private List connections;
private static String label = "Fix Copy Pasted Connections Command";
public FixCopyPastedConnectionsCommand(
TransactionalEditingDomain domain, List connections) {
super(domain, label, getWorkspaceFiles(connections));
this.connections = connections;
// TODO Auto-generated constructor stub
}
@Override
protected CommandResult doExecuteWithResult(IProgressMonitor monitor,
IAdaptable info) throws ExecutionException {
for (Object c : connections) {
Connection conn = (Connection) c;
End src = conn.getSrc();
End dst = conn.getDst();
if (src.getOutgoingConnections().contains(conn) == false) {
conn.setSrc(null);
conn.setSrc(src);
}
if (dst.getIncomingConnections().contains(conn) == false) {
conn.setDst(null);
conn.setDst(dst);
}
}
return CommandResult.newOKCommandResult();
}
}
......
protected void handleNotificationEvent(Notification event) {
/*
* fix some copy & paste issues
*/
if (event.getFeature().equals(
Bluenose2Package.eINSTANCE.getPipeline_Connections())) {
List connections = null;
if (event.getEventType() == Notification.ADD) {
connections = Collections.singletonList(event.getNewValue());
} else if (event.getEventType() == Notification.ADD_MANY) {
connections = (List) event.getNewValue();
}
if (connections != null) {
TransactionalEditingDomain domain = TransactionUtil
.getEditingDomain(connections.get(0));
AbstractTransactionalCommand command = new FixCopyPastedConnectionsCommand(
domain, connections);
executeCommand(new ICommandProxy(command));
}
}
super.handleNotificationEvent(event);
}
}
