Gets the record types available in this object. A record Type explicitly indicates the specification of an interface to the record. A record may or may not inherit other record interfaces through interface inheritance in which case support of a record type may not be explicit in the returned list. Interoperability with the typed interface to this object should be performed through hasRecordType().

Tests if this object supports the given record Type. The given record type may be supported by the object through interface/type inheritence. This method should be checked before retrieving the record interface.
