Examples of DependencyDeclaration

ptolemy.actor.util.DependencyDeclaration
An instance of DependencyDeclaration is an attribute that declares variable dependence information of a parameter. This attribute is usually created in a parameter, when necessary, during the preinitialize method of an actor. This class is used primarily by the ConstVariableModelAnalysis class to determine a change context for parameters whose value dependence is not declared through an expression reference, but maintained by the actor's Java code instead.
This attribute is not persistent by default, so it will not be exported into a MoML representation of the model. @author Steve Neuendorffer @version $Id: DependencyDeclaration.java,v 1.22 2005/07/08 19:39:37 cxh Exp $ @since Ptolemy II 4.0 @Pt.ProposedRating Yellow (neuendor) @Pt.AcceptedRating Yellow (neuendor) @see ptolemy.actor.util.ConstVariableModelAnalysis
