module NewRelic
#
# This class allows the current transaction to be passed to a Thread so that nested segments can be created from the operations performed within the Thread's block.
# To have the New Relic Ruby agent automatically trace all of your applications threads,
# enable the +instrumentation.thread.tracing+ configuration option in your newrelic.yml.
#
# Note: disabling the configuration option +instrumentation.thread+ while using this class can cause incorrectly nested spans.
#
# @api public
class TracedThread < Thread
#
# Creates a new Thread whose work will be traced by New Relic.
# Use this class as a replacement for the native Thread class.
# Example: Instead of using +Thread.new+, use:
#
# NewRelic::TracedThread.new { execute_some_code }
#
# @api public
