/** 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.
