org.apache.harmony.awt.nativebridge.VoidPointer
This class represents pointer to memory for working with native functions. It is an analogue of void* C type. Every pointed object can be direct native object or Java object. In both cases NativeBridge provides correct passing addresses to native functions, native address is passed as is, Java object will be implicitly locked and address of lock will be passed to native. NULL pointer can't be wrapped by this object, NULL is represents by Java null value. @see org.apache.harmony.misc.accessors.MemoryAccessor @see org.apache.harmony.misc.accessors.ArrayAccessor
