Referenced by getCommand().

Here is the call graph for this function:

getCommand()

ComponentCommand * ProDePortEditPolicy::getCommand ( Request *  request )

virtual

Returns the Command corresponding to the type of the Request.

Parameters

request

Request to be handled.

Returns

NULL if the Request cannot be handled.

Note

ConnectCommand is not yet implemented, thus returns always NULL.

Implements EditPolicy.
