The ODynmaicLoader provides a special load on call mechanism for dynamic libraries which support a C-API.
The libraries must provide a struct with function pointers for all supported C functions. The loader loads the specified library and call the specified initialization function to initialize the function pointers with the real functions. Furthermore provides the loader a reference counter for the library. When the last instance of the laoder will be destroyed the loader will unload the library.
salhelper::ODynamicLoader< API >::ODynamicLoader | ( | ) | throw () [inline] |
Default constructor.
salhelper::ODynamicLoader< API >::ODynamicLoader | ( | const ::rtl::OUString & | strModuleName, |
const ::rtl::OUString & | strInitFunction | ||

Constructor, loads the library if necessary otherwise the refernece count will be increased.
strModuleName | specifies the library name. |
strInitFunction | specifies the name of the initialization function. |

Copy constructor.
salhelper::ODynamicLoader< API >::~ODynamicLoader | ( | ) | throw () [inline] |
Destructor, decrease the reference count and unload the library if it is tha last instance.

returns a poiner to the initialized API function structure.
sal_Bool salhelper::ODynamicLoader< API >::isLoaded | ( | ) | const throw () [inline] |
checks if the loader works on a loaded and initialized library.
