The contains method. This method returns true if the SBB entity
represented by the SBB local object specified by the input argument is a
member of this child relation. If the method argument is not an SBB local
object, is an invalid SBB local object, or is an SBB local object whose
underlying SBB entity is not a member of this child relation, then this
method returns false.
