Subject: Move HashMapDb to its own bundle
X-Git-Tag: release/beryllium~140
X-Git-Url: https://git.opendaylight.org/gerrit/gitweb?a=commitdiff_plain;h=6e425e7db05425792380c0ae5e0bea028b25a111;p=lispflowmapping.git

Move HashMapDb to its own bundle

HashMapDb is a simple, in memory implementation of ILispDAO, the
interface that defines the API for the interaction with the Map-Server's
mappings database. Until now, HashMapDb was part of
mappingservice.implementation but with this commit it is moved to its
own mappingservice.inmemorydb bundle.

An important feature is that a ILispDAO implementation is now injected
into mappingservice.implementation at runtime through config-subsystem.
As a result, InMemoryDb can be easily swapped with other implementations.
