              ix.icore.domain.Constraint

All Implemented Interfaces:

Annotated, IXObject, Sendable, java.io.Serializable, java.lang.Cloneable

public class Constraint
extends Constrainer
implements java.io.Serializable, java.lang.Cloneable, Sendable

A general-purpose container for constraint information. In most cases, the type and relation will together determine (in a fairly straightforward way) what the parameters should contain.
