org.eclipse.emf.query.ocl.conditions.BooleanOCLCondition<C,CLS,E>
public class BooleanOCLCondition<C,CLS,E>
A specialized OCL condition class that is used to apply boolean-valued OCL
expressions to EObjects. These are commonly used to express
invariant constraints; they are not typically
evaluated but are usually
checked for isSatisfied(EObject).
