oclIsKindOf( typespec : Class ) : Boolean

Returns true if the type of self corresponds to the type or supertype of typespec - otherwise, returns false. This operation allows users to check the class hierarchy of self much like they would an instance of Java.

Expression	Result
anEmployee.oclIsKindOf(Employee)	true
anEmployee.oclIsKindOf(Person)	true
aCat.oclIsKindOf(Person)	false

To check if an object has the exact type and not only inherits a type use OCLOperators oclIsTypeOf
