Examples of ptolemy.kernel.ComponentPort.link()

ptolemy.kernel.ComponentPort.link()
Link this port with the specified relation. Note that a port may be linked to the same relation more than once, in which case the link will be reported more than once by the linkedRelations() method. If the argument is null, then create a null link (on the outside). This method is write-synchronized on the workspace and increments its version number. @param relation The relation to link to. @exception IllegalActionException If the link crosses levels ofthe hierarchy, or the port has no container, or the relation is not a ComponentRelation, or if the port is contained by a class definition.

                            if (!connectedPorts.contains(newPort)) {
                                ComponentRelation relation = newRelation(uniqueName("relation"));
                                newPort.link(relation);
                                insidePort.link(relation);
                            }
                        }
                    } finally {
