##
Instance Method Detail

abstract def accept : IO #

Accepts an incoming connection and returns the client socket.

    require "socket"

    server = TCPServer.new(2202)
    while true
      socket = server.accept
      socket.puts Time.utc
      socket.close
    end

If the server is closed after invoking this method, an `IO::Error` (closed stream) exception must be raised.

def accept(&) #

Accepts an incoming connection and yields the client socket to the block. Eventually closes the connection when the block returns.

Returns the value of the block. If the server is closed after invoking this method, an `IO::Error` (closed stream) exception will be raised.

    require "socket"

    server = TCPServer.new(2202)
    server.accept do |socket|
      socket.puts Time.utc
    end

abstract def accept? : IO? #

Accepts an incoming connection and returns the client socket.

Returns `nil` if the server is closed after invoking this method.

    require "socket"

    server = TCPServer.new(2202)
    while socket = server.accept?
      socket.puts Time.utc
      socket.close
    end

def accept?(&) #

Accepts an incoming connection and yields the client socket to the block. Eventually closes the connection when the block returns.

Returns the value of the block or `nil` if the server is closed after invoking this method.

    require "socket"

    server = UNIXServer.new("/tmp/service.sock")
    server.accept? do |socket|
      socket.puts Time.utc
    end
