Method Detail

getCommand

public Command getCommand(Request request)

Returns the appropriate Command for the request type given. Handles creating, moving and deleting bendpoints. The actual creation of the command is taken care of by subclasses implementing the appropriate methods.

ConnectionBendpointEditPolicy.getCreateBendpointCommand(BendpointRequest), ConnectionBendpointEditPolicy.getMoveBendpointCommand(BendpointRequest), ConnectionBendpointEditPolicy.getDeleteBendpointCommand(BendpointRequest)

getBendpointsChangedCommand

protected Command getBendpointsChangedCommand(BendpointRequest request)

Method getBendpointsChangedCommand. This method will return a SetBendpointsCommand with the points retrieved from the user feedback in the figure.

Parameters:

request - BendpointRequest from the user gesture for moving / creating a bendpoint

Returns:

Command SetBendpointsCommand that contains the point changes for the connection.

getBendpointsChangedCommand

protected Command getBendpointsChangedCommand(Connection connection,
                                              Edge edge)

Method getBendpointsChangedCommand Different signature method that allows a command to constructed for changing the bendpoints without requiring the original Request.

Parameters:

connection - Connection to generate the bendpoints changed command from

edge - notation element that the command will operate on.

Returns:

Command SetBendpointsCommand that contains the point changes for the connection.

getSetBendpointCommand

protected Command getSetBendpointCommand(SetAllBendpointRequest request)

Method getSetBendpointCommand. This method returns a command that executes the REQ_SET_ALL_BENDPOINT request

Parameters:

request - SetAllBendpointRequest that stores the points to be set by the command.

Returns:

Command to be executed.
