Examples of ChangeRequest

de.fhkn.in.uce.stun.attribute.ChangeRequest
The {@link ChangeRequest} is the implementation of {@link Attribute} for theCHANGE-REQUEST STUN attribute which is defined in RFC 5780. @author Alexander Diener (aldiener@htwg-konstanz.de)
model.devscore.dynamic.ChangeRequest
The Class ChangeRequest. @author Jan Himmelspach @version 1.0
org.jboss.dna.graph.request.ChangeRequest
A Request to make changes in a graph.
ptolemy.kernel.util.ChangeRequest
Abstract base class for change requests. A change request is any modification to a model that might be performed during execution of the model, but where there might only be certain phases of execution during which it is safe to make the modification. Such changes are also called mutations.
A typical use of this class is to define an anonymous inner class that implements the _execute() method to bring about the desired change. The instance of that anonymous inner class is then queued with an instance of NamedObj using its requestChange() method. The execute() method must be called only once; attempting to call it multiple times will trigger an exception.
Concrete derived classes can be defined to implement mutations of a certain kind or in a certain way. Instances of these classes should be queued with a NamedObj, just like an anonymous inner class extending this class. MoMLChangeRequest is such a concrete derived class, where the mutation is specified as MoML code. @author Edward A.
