Detailed Description

ORB-specific PortableInterceptor::PolicyFactory registry.

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

Definition at line 41 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 58 of file PolicyFactory_Registry.h.
