- All Implemented Interfaces:
Streamable
Portable Interceptors Current (also known as
PICurrent
)
is merely a slot table, the slots of which are used by each service to
transfer their context data between their context and the request's or
reply's service context. Each service which wishes to use PICurrent
reserves a slot or slots at initialization time and uses those slots
during the processing of requests and replies.
Before an invocation is made, PICurrent is obtained via a call to
ORB.resolve_initial_references( "PICurrent" )
. From within
the interception points, the data on PICurrent that has moved from the
thread scope to the request scope is available via the
get_slot
operation on the RequestInfo
object.
A PICurrent can still be obtained via
resolve_initial_references
, but that is the Interceptor's
thread scope PICurrent.
