public interface DataPostProcessor
Use DataPostProcessor to add custom post-processing logic (like manipulating
the data returned by the service call) to the operation after a back-end
service call is made by the Connector. If the Connector execution is
successful, then result
object will have "opstatus" of type
Param
with value (zero for success
and non-zero for failure).
If either the pre-processor or the Connector throws an exception then instead
of execute
method, OnException
method is called.Refer
documentation of OnException
for more details.
Note: DataPostProcessor is a singleton - only one instance of this class is created and the same is used for every service call. Therefore, DataPostProcessor should not have any user/request specific data or state. Any data common to all the users/requests may be stored.
