Because bridges sometimes can not be generated in an address space,
the implementation needs to check the address space of the caller by
comparing the process ID against its own. That ID is
provided by the UNO runtime.
All objects, whether they are part of the UNO object model or not,
are carried in an any
. The representation of this object
is heavily model-dependent and has to be specified in the following list:
- UNO:
- The any carries normal UNO types, which can be any base type,
struct, sequence, enum or interface.
- OLE:
- The any carries an
unsigned long
(on 32-bit systems)
or an unsigned hyper
(on 64-bit systems), which is
interpreted as a variant pointer. The any does not control the
lifetime of the represented variant. That implies that the caller
has the responsibility of freeing the OLE resources represented
by the any value.
- JAVA:
- not specified yet.
- CORBA:
- not specified yet.
Any implementation can supply its own bridges to other object
models by implementing this interface and returning the bridge
when the method XBridgeSupplier2::createBridge()
is called with itself as the first parameter.
