Code reformat.
Extend support for neighour triggers -- include neighbour availabilty
when updating and inserting.
1. Only re-subscribe on update and insert (was attempting on delete).
2. Update subscriptions when a neighbour is added/updated.
Merge remote-tracking branch 'origin/master' into feat/node-trigger-handling
Corrected a defect that stopped attempting to subscribe after the first
error status; now tries all possible subscriptions.
To string no longer returns the active service descriptor (this was the
source of null pointer exceptions).
Code added to close the result channel after use.
Test added to ensure that populated node result sets are not overwritten
by empty result sets from loopback queries.
Fix null pointer when no mode is given for a service type.
Merge branch 'feat/node-trigger-handling' of ssh://git@github.com/edgware/edgware.git into feat/node-trigger-handling
Additional/updated default configuration properties.
Re-format comment.
