Examples of ptolemy.kernel.Port.link()

• ptolemy.kernel.Port.link()
  Link this port with a relation, and notify the container by calling its connectionsChanged() method. The relation is required to be at the same level of the hierarchy as the entity that contains this port, meaning that the container of the relation is the same as the container of the container of the port. That is, level-crossing links are not allowed.

  If the argument is null, then create a null link. 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. In derived classes, the relation may be required to be an instance of a particular subclass of Relation (this is checked by the _checkLink() protected method). This method is write-synchronized on the workspace and increments its version number. @param relation The relation to link to this port. @exception IllegalActionException If the link would cross levels ofthe hierarchy, or the relation is incompatible, or the port has no container, or the port is not in the same workspace as the relation, or if the port is contained by a class definition.
