#
|
|
# 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"
|
|
#
