Typedef Documentation

typedef int(* factory_method_t)(factory_library_op_t op, int tag, va_list args)

Function type for the primary library function interface. Parameters: op  The sub-operation to execute. tag  The first tag in the tag list. args  The remaining tags in the tag list. Returns: Zero if the operation succeeded, an errno value otherwise. Definition at line 66 of file factory_library.h. Referenced by FactoryLibrary_ltdl::FactoryLibrary_ltdl(), flFactoryMethod(), FactoryLibrary_ltdl::OpenLibrary(), and scan_file().

Enumeration Type Documentation

anonymous enum

Argument tags for the factory_method_t functions. Enumeration values: FMA_TAG_DONE  () - Terminate the tag list FMA_ORB  (CORBA::ORB_ptr) - Pointer to an ORB FMA_POA  (PortableServer::POA_ptr) - Pointer to a POA FMA_HeyParser  (HeyParser *) - Pointer to an active HeyParser FMA_HeyServerHint  (const char *) - Hint for the type of server FMA_StandardOut  (ostream *) - Standard output stream FMA_StandardError  (ostream *) - Standard error stream FMA_USER_BASE  Base for user tags. Definition at line 47 of file factory_library.h.

enum factory_library_op_t

Sub-operations for the primary library function below. Enumeration values: FLO_MIN  The minimum legal value. FLO_QUERY  Ask the library if it contains support for something. FLO_HEY  Ask the library to handle a 'hey' request. FLO_MAX  The maximum legal value. Definition at line 37 of file factory_library.h.

Function Documentation

int FACTORY_METHOD_SYMBOL (  factory_library_op_t  op, int  tag, va_list  args )

The primary library function. This function provides a generic interface to the capabilities of a shared library. Parameters: op  The sub-operation to execute. tag  The first tag in the tag list. args  The remaining tags in the tag list. Returns: Zero if the operation succeeded, an errno value otherwise. Definition at line 206 of file AllupFactory.cc. References afAllupHey(), afFactoryLibraryHey(), FLO_HEY, FLO_QUERY, FMA_HeyParser, FMA_HeyServerHint, FMA_ORB, FMA_POA, FMA_StandardError, FMA_StandardOut, FMA_TAG_DONE, and tfHey().

Here is the call graph for this function:

int flFactoryMethod (  factory_method_t  fm, factory_library_op_t  op, int  tag, ...  )

Wrapper function that calls a given factory_method_t with the arguments given on the stack. Parameters: fm  The primary library function to pass the request to. op  The sub-operation to execute. tag  The first tag in the tag list. Returns: Zero if the operation succeeded, an errno value otherwise. Definition at line 24 of file factory_library.c. References factory_method_t, FLO_MAX, FLO_MIN, and require.
