Examples of ptolemy.graph.InequalityTerm

ptolemy.graph.InequalityTerm
An interface for a term in an inequality over a CPO. A term is either a constant, a variable, or a function. In some applications, a term may be associated with an Object. For example, the value of the term may represent a certain characteristic of an Object, and it is necessary to get a reference of that Object from a term. This can be done through the getAssociatedObject() method of this interface. @author Yuhong Xiong @version $Id: InequalityTerm.java,v 1.47 2006/03/29 00:01:07 cxh Exp $ @since Ptolemy II 0.2 @Pt.ProposedRating Green (yuhong) @Pt.AcceptedRating Green (kienhuis) @see CPO
