Manages dynamic libraries.
The Dynamic Library Manager provides a platform independent way to work with dynamic library. It load a specific dynamic library, and can returns specific symbol exported by the dynamic library.
If an error occurs, a DynamicLibraryManagerException is thrown.
| typedef void* DynamicLibraryManager::LibraryHandle | 
| typedef void* DynamicLibraryManager::Symbol | 
| CPPUNIT_NS_BEGIN DynamicLibraryManager::DynamicLibraryManager | ( | const std::string & | libraryFileName | ) | 
Loads the specified library.
| libraryFileName | Name of the library to load. | 
| DynamicLibraryManagerException | if a failure occurs while loading the library (fail to found or load the library). | 
| DynamicLibraryManager::~DynamicLibraryManager | ( | ) | 
Releases the loaded library..
| 
 | private | 
Prevents the use of the copy constructor.
| 
 | private | 
Returns a pointer on the specified symbol exported by the library.
May throw any exceptions (indicates failure).
| symbol | Name of the symbol exported by the library. | 
NULL indicates failure. | 
 | private | 
Loads the specified library.
May throw any exceptions (indicates failure).
| libraryName | Name of the library to load. | 
NULL indicates failure. | 
 | private | 
Releases the loaded library.
The handle of the library to free is in m_libraryHandle. It is never NULL. 
| DynamicLibraryManager::Symbol DynamicLibraryManager::findSymbol | ( | const std::string & | symbol | ) | 
Returns a pointer on the specified symbol exported by the library.
| symbol | Name of the symbol exported by the library. | 
NULL. | DynamicLibraryManagerException | if the symbol is not found. | 
| 
 | private | 
Returns detailed information about doLoadLibrary() failure.
Called just after a failed call to doLoadLibrary() to get extra error information.
| 
 | private | 
Loads the specified library.
| libraryName | Name of the library to load. | 
| DynamicLibraryManagerException | if a failure occurs while loading the library (fail to found or load the library). |
