X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e2cc251bc27cdf0595af8f97d14e2c8a9983f73c;p=platform%2Fupstream%2Fiotivity.git

CPP Default entity handler functionality and misc fixes.

Patch 1:
Fixed simpleclient to work with Observe, along with JSON representation changes.

Patch 2:
Fixed some stuff in simpleclientserver, and other things.

Patch 3:
C++ change to discover multiple resources on a server

Patch 4:
C++ Default handler functionality.
Fixes in C Stack for Default entity hanlder for C++ stack to work.
Few other misc. fixes.

Patch 5: Changed entityHandler name to EntityHandler.

Added Try/Catch around read_json

Fix for simpleclientserver
