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.

Retrieves the slot data the application set in PICurrent via 
get_slot.  The data is in the form of an Any. 


If the given slot has not been set, an Any containing a type code 
with a TCKind value of tk_null and no value 
is returned. 

Params:
  • id – The SlotId of the slot from which the data will 
    be returned.
Throws:
  • InvalidSlot – thrown if get_slot is called on a slot that 
    has not been allocated.
  • BAD_INV_ORDER – thrown if get_slot is called 
    from within an ORB initializer
Returns:The data, in the form of an Any, of the given slot identifier.

Sets data in a slot. The data is in the form of an Any. If data 
already exists in that slot, it is overridden. 

Params:
  • id – The SlotId of the slot to which the data will 
    be set.
  • data – The data, in the form of an Any, which will be set 
    to the identified slot.
Throws:
  • InvalidSlot – thrown if set_slot is called on 
    a slot that has not been allocated.
  • BAD_INV_ORDER – thrown if set_slot is called 
    from within an ORB initializer.
