# <!-- rdoc-file=thread.c -->
# ThreadGroup provides a means of keeping track of a number of threads as a
# group.
#
# A given Thread object can only belong to one ThreadGroup at a time; adding a
# thread to a new group will remove it from any previous group.
#
# Newly created threads belong to the same group as the thread from which they
# were created.
#
class ThreadGroup < Object
# <!--
# rdoc-file=thread.c
# - thgrp.add(thread) -> thgrp
# -->
# Adds the given `thread` to this group, removing it from any other group to
# which it may have previously been a member.
#
# puts "Initial group is #{ThreadGroup::Default.list}"
# tg = ThreadGroup.new
# t1 = Thread.new { sleep }
# t2 = Thread.new { sleep }
# puts "t1 is #{t1}"
# puts "t2 is #{t2}"
# tg.add(t1)
# puts "Initial group now #{ThreadGroup::Default.list}"
# puts "tg group now #{tg.list}"
#
# This will produce:
#
# Initial group is #<Thread:0x401bdf4c>
# t1 is #<Thread:0x401b3c90>
# t2 is #<Thread:0x401b3c18>
# Initial group now #<Thread:0x401b3c18>#<Thread:0x401bdf4c>
# tg group now #<Thread:0x401b3c90>

def add: (Thread thread) -> ThreadGroup
# <!--
# rdoc-file=thread.c
# - thgrp.enclose -> thgrp
# -->
# Prevents threads from being added to or removed from the receiving
# ThreadGroup.

# New threads can still be started in an enclosed ThreadGroup.
