Issue Type: New Feature
Components: C++ Broker
Affects Versions: 0.12
Environment: All
Reporter: Fraser Adams
Priority: Minor
C++ broker ManagementAgent currently only supports QMF2 _what = "OBJECT"
queries.
This is a patch to add support for OBJECT_ID, SCHEMA_ID and SCHEMA queries.
The "SCHEMA" query support makes use of the QMF1 schema information already
provided for each Management Object and "transcodes" the info into QMF2 Map
message format.
The main reason that I took this approach is that I'm not familiar with the
schema code generation stuff, so I couldn't generate a "mapEncodeSchema()"
method for each Management class, however as it happens That approach would
also need changes to registerClass(), registerEvent(), SchemaClass and a few
other places because things are a bit tied to the QMF1 writeSchemaCall
signature so doing the transcoding is least disruptive to the existing code
base and the scope of changes to support the feature are limited to
ManagementAgent::handleGetQueryLH() though to be fair that's getting quite big
now so it might be worth decomposing it into some smaller methods.
