Detailed Description

ORB-specific PortableInterceptor::PolicyFactory registry.

ORB-specific registry that contains all portable interceptor policy factories.

Definition at line 40 of file PolicyFactory_Registry.h.

Member Typedef Documentation

typedef ACE_Map_Manager<CORBA::PolicyType, PortableInterceptor::PolicyFactory_ptr, ACE_Null_Mutex> TAO_PolicyFactory_Registry::TABLE

The type of table that maps policy type to policy factory.

Note:

An ACE_Null_Mutex is used for this type since policy factories are only registered when CORBA::ORB_init() is called, at which a point a lock has already been acquired. In short, the table is only modified during ORB bootstrap-time.

Definition at line 57 of file PolicyFactory_Registry.h.

CORBA::Policy_ptr TAO_PolicyFactory_Registry::_create_policy

(

}

CORBA::Policy_ptr TAO_PolicyFactory_Registry::create_policy	(	CORBA::PolicyType	type,
		const CORBA::Any &	value
	)

Construct a policy of the given type with the information contained in the CORBA::Any value.

bool TAO_PolicyFactory_Registry::factory_exists

const

Check if a PolicyFactory corresponding to the given type, exists.

void TAO_PolicyFactory_Registry::register_policy_factory	(	CORBA::PolicyType	type,
		PortableInterceptor::PolicyFactory_ptr	policy_factory
	)

Register a PolicyFactory with the underlying PolicyFactory sequence. This method should only be called during ORB initialization.
