From 57a44626324326fc3b29042398d2ccdaec5a7758 Mon Sep 17 00:00:00 2001 From: Daniel Cruz Date: Wed, 6 Mar 2019 10:45:09 -0600 Subject: Add Network Logging Feature This is part 1 of introducing the mdc filter feature. Network logging has to have interception points in order to pre/post process messages coming in from a network endpoint. The OrderedService interface and OrderedServiceImpl of the drools-pdp project have now been migrated to common but is also left in drools-pdp to mitigate disruption to existing features. However for features that need to use common's OrderedServiceImpl and drools-pdp version of OrderedServiceImpl there will be a conflict with getSequenceNumber(). So a migration of the other features is suggested. Network logging is moved to its own util class so that feature hooks can be invoked any time an event is being logged by a network logger. This util class will also be accessible to drools-applications in the case where drools-applications would like to invoke network logging features for REST events.
