Class CompoundProposition

java.lang.Object
  org.kuali.rice.krms.framework.engine.CompoundProposition

All Implemented Interfaces:

public final class CompoundProposition
extends Object
implements org.kuali.rice.krms.framework.engine.Proposition

An implementation of Proposition which holds other Propositions and a LogicalOperator. NOTE - this is a patched version of CompoundProposition which fixes bugs in evaluation "OR"-ed propositions
