Examples of ptolemy.kernel.util.NamedObj.requestChange()

ptolemy.kernel.util.NamedObj.requestChange()
Request that the given change be executed. In this base class, delegate the change request to the container, if there is one. If there is no container, then execute the request immediately, unless this object is deferring change requests. If setDeferChangeRequests() has been called with a true argument, then simply queue the request until either setDeferChangeRequests() is called with a false argument or executeChangeRequests() is called. If this object is already in the middle of executing a change request, then that execution is finished before this one is performed. Change listeners will be notified of success (or failure) of the request when it is executed. @param change The requested change. @see #executeChangeRequests() @see #setDeferringChangeRequests(boolean) @see Changeable
