#
# Toaster helper class
#
# Copyright (C) 2013 Intel Corporation
#
# Released under the MIT license (see COPYING.MIT)
#
# This bbclass is designed to extract data used by OE-Core during the build process,
# for recording in the Toaster system.
# The data access is synchronous, preserving the build data integrity across
# different builds.
#
# The data is transferred through the event system, using the MetadataEvent objects.
#
# The model is to enable the datadump functions as postfuncs, and have the dump
# executed after the real taskfunc has been executed. This prevents task signature changing
# is toaster is enabled or not. Build performance is not affected if Toaster is not enabled.
#
# To enable, use INHERIT in local.conf:
#
# INHERIT += "toaster"
#
