ThreadGroup provides a means of keeping track of a number of threads as a group. A Thread can belong to only 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.
konstanter
Default Default thread group.

klassemetoder
new ThreadGroup.new -> thgrp

instansmetoder
add thgrp.add( aThread ) -> thgrp

Adds the given thread to this group, removing it from any other group to which it may have previously belonged.

puts "Initial group is #{ThreadGroup::Default.list}"
tg = ThreadGroup.new
t1 = Thread.new { sleep 10 }
t2 = Thread.new { sleep 10 }
puts "t1 is #{t1}"
puts "t2 is #{t2}"
tg.add( t1 )
puts "Initial group now #{ThreadGroup::Default.list}"
puts "tg group now #{tg.list}"
produces:
Initial group is #<Thread:0x401bc5c8>
t1 is #<Thread:0x401b34a0>
t2 is #<Thread:0x401b3450>
Initial group now #<Thread:0x401b3450>#<Thread:0x401bc5c8>
tg group now #<Thread:0x401b34a0>
