Detailed Description

The policy-driven details for a registered server request interceptor.

Each time a server request interceptor is registered with an ORB, a ServerRequestDetails object will be created and associated with the registered server request interceptor. If the interceptor is registered with policies, the policies will be used to adjust the values in the ServerRequestDetails appropriately.

ACE_INLINE bool TAO::ServerRequestDetails::should_be_processed

(

bool

is_remote_request

)

const

Returns true if the ProcessingMode setting permits the "firing" of the associated server request interceptor based upon the remote vs. collocated nature of the current servant request that is being dispatched.
