Method Summary

Modifier and Type	Method and Description
BlockWellDefinedness	combine(WellDefinednessCheck wdc, TermServices services) Combines two well-definedness checks having the same name, id, target, type, behaviour and are either both model fields or both not a model field.

KeYJavaType	getKJT() Returns the KeYJavaType representing the class/interface to which the specification element belongs.
BlockContract	getStatement()
String	getTypeName() Returns technical name for the contract type.
VisibilityModifier	getVisibility() Returns the visibility of the invariant (null for default visibility)
Contract	setID(int newId) Returns a contract which is identical this contract except that the id is set to the new id.
Contract	setTarget(KeYJavaType newKJT, IObserverFunction newPM) Returns a contract which is identical to this contract except that the KeYJavaType and IObserverFunction are set to the new values.
