Detailed Description

The static (global) resoures of all POA's.

This class is used by the POA to store the resources global to all POA's. All instance variables that would have been declared "static" in TAO_Regular_POA, should be declared in this class to avoid the "static initialization order fiasco" as described in http://www.parashift.com/c++-faq-lite/ctors.html#faq-10.11. Briefly, this is the problem that occurs if any static initializers in any other code call into set static members of TAO_Regular_POA. Since the order in which these initializers execute is unspecified, uninitialized members can be accessed.

Member Data Documentation

ACE_CString TAO_POA_Static_Resources::imr_client_adapter_name_

Name of the service object for functions that make calls on the Implementation Repository. The default value is "ImR_Client_Adapter". If TAO_IMR_CLient is linked, imr_client_adapter_name() will be called to set the value to "Concrete_ImR_Client_Adapter".

Definition at line 829 of file Root_POA.h.

TAO_POA_Static_Resources * TAO_POA_Static_Resources::initialization_reference_ [static, private]

Initial value:

  TAO_POA_Static_Resources::instance ()

Mostly unused variable whose sole purpose is to enforce the instantiation of a TAO_POA_Static_Resources instance at initialization time.

Definition at line 841 of file Root_POA.h.

TAO_POA_Static_Resources * TAO_POA_Static_Resources::instance_ = 0 [static, private]

The singleton instance.

Definition at line 836 of file Root_POA.h.

Referenced by instance().

ACE_CString TAO_POA_Static_Resources::ort_adapter_factory_name_

Name of the factory object used to adapt function calls on the PortableInterceptor interfaces ORT. The default value is "ObjectReferenceTemplate_Adapter_Factory". If the ORT library is linked, the corresponding accessor function objectreferencefactory_adapter_factory_name() will be called to set the value to "Concrete_ObjectReferenceTemplate_Adapter_Factory".
