[static]

Return a singleton instance of this class.

  return ACE_Singleton<Data_Types_Register, ACE_SYNCH_MUTEX>::instance();
}

TypeSupport_ptr OpenDDS::DCPS::Data_Types_Register::lookup	(	DDS::DomainParticipant_ptr	domain_participant,
		const char *	type_name
	)			const

Find a data type by its type name.

Returns:

the TypeSupport object registered as type_name Otherwise returns TypeSupport::_nil()

DDS::ReturnCode_t OpenDDS::DCPS::Data_Types_Register::register_type	(	DDS::DomainParticipant_ptr	domain_participant,
		const char *	type_name,
		TypeSupport_ptr	the_type
	)

Register a type.

Returns:

RETCODE_OK if the type_name is unique to the domain participant or the type_name is already registered to the_type's class. Otherwise returns RETCODE_ERROR
