#
# This class watches for termination of multiple threads.  Basic functionality
# (wait until specified threads have terminated) can be accessed through the
# class method ThreadsWait::all_waits.  Finer control can be gained using
# instance methods.
#
# Example:
#
#   ThreadsWait.all_waits(thr1, thr2, ...) do |t|
#     STDERR.puts "Thread #{t} has terminated."
#   end
#
#
#   th = ThreadsWait.new(thread1,...)
#   th.next_wait # next one to be done
#
#
class ThreadsWait
  extend Exception2MessageMapper
  def_exception("ErrNoWaitingThread", "No threads for waiting.")
  def_exception("ErrNoFinishedThread", "No finished threads.")

#
  # Waits until all specified threads have terminated.  If a block is provided,
  # it is executed for each thread as they terminate.
  #
  def ThreadsWait.all_waits(*threads) # :yield: thread
    tw = ThreadsWait.new(*threads)
    if block_given?
      tw.all_waits do |th|
        yield th
      end
    else
      tw.all_waits
    end
  end

#
  # Creates a ThreadsWait object, specifying the threads to wait on.
  # Non-blocking.
  #
  def initialize(*threads)
    @threads = []
    @wait_queue = Thread::Queue.new
    join_nowait(*threads) unless threads.empty?
  end

# Returns the array of threads that have not terminated yet.
  attr_reader :threads

#
  # Returns +true+ if there are no threads in the pool still running.
  #
  def empty?
    @threads.empty?
  end

#
  # Returns +true+ if any thread has terminated and is ready to be collected.
  #
  def finished?
    !@wait_queue.empty?
  end

#
  # Waits for specified threads to terminate, and returns when one of
  # the threads terminated.
  #

#
  # Specifies the threads that this object will wait for, but does not actually
  # wait.

#
  # Waits until any of the specified threads has terminated, and returns the one
  # that does.
  #

  # is true, and there is no terminated thread, raises +ErrNoFinishedThread+.
  #

    rescue ThreadError
      ThreadsWait.fail ErrNoFinishedThread
    end
  end

#
  # Waits until all of the specified threads are terminated.  If a block is
  # supplied for the method, it is executed for each thread termination.
  #
  # Raises exceptions in the same manner as +next_wait+.
