| /** the UNO3_GETIMPLEMENTATION_* macros implement a static helper function |
| that gives access to your implementation for a given interface reference, |
| if possible. |
| |
| Example: |
| MyClass* pClass = MyClass::getImplementation( xRef ); |
| |
| Usage: |
| Put a UNO3_GETIMPLEMENTATION_DECL( classname ) inside your class |
| definitian and UNO3_GETIMPLEMENTATION_IMPL( classname ) inside |
| your cxx file. Your class must inherit ::com::sun::star::uno::XUnoTunnel |
| and export it with queryInterface. Implementation of XUnoTunnel is |
| done by this macro. |
