Explanation of the conflict used by exceptions to print useful messages

Gets the global do_not_reverse_lookup flag.

BasicSocket.do_not_reverse_lookup  #=> false

Sets the global do_not_reverse_lookup flag.

The flag is used for initial value of do_not_reverse_lookup for each socket.

s1 = TCPSocket.new("localhost", 80)
p s1.do_not_reverse_lookup                 #=> true
BasicSocket.do_not_reverse_lookup = false
s2 = TCPSocket.new("localhost", 80)
p s2.do_not_reverse_lookup                 #=> false
p s1.do_not_reverse_lookup                 #=> true

Gets the do_not_reverse_lookup flag of basicsocket.

require 'socket'

BasicSocket.do_not_reverse_lookup = false
TCPSocket.open("www.ruby-lang.org", 80) {|sock|
  p sock.do_not_reverse_lookup      #=> false
}
BasicSocket.do_not_reverse_lookup = true
TCPSocket.open("www.ruby-lang.org", 80) {|sock|
  p sock.do_not_reverse_lookup      #=> true
}

Sets the do_not_reverse_lookup flag of basicsocket.

TCPSocket.open("www.ruby-lang.org", 80) {|sock|
  p sock.do_not_reverse_lookup       #=> true
  p sock.peeraddr                    #=> ["AF_INET", 80, "221.186.184.68", "221.186.184.68"]

}

Sets the basic list of characters that signal a break between words for the completer routine. The default is the characters which break words for completion in Bash: “ tn"\‘`@$><=;|&{(”.

Raises NotImplementedError if the using readline library does not support.

Gets the basic list of characters that signal a break between words for the completer routine.

Raises NotImplementedError if the using readline library does not support.

The index to insert activated gem paths into the $LOAD_PATH. The activated gem’s paths are inserted before site lib directory by default.

The iterator version of the strongly_connected_components method. obj.each_strongly_connected_component is similar to obj.strongly_connected_components.each, but modification of obj during the iteration may lead to unexpected results.

each_strongly_connected_component returns nil.

The iterator version of the TSort.strongly_connected_components method.

The graph is represented by each_node and each_child. each_node should have call method which yields for each node in the graph. each_child should have call method which takes a node argument and yields for each child node.

g = {1=>[2, 3], 2=>[4], 3=>[2, 4], 4=>[]}
each_node = lambda {|&b| g.each_key(&b) }
each_child = lambda {|n, &b| g[n].each(&b) }
TSort.each_strongly_connected_component(each_node, each_child) {|scc| p scc }
#=> [4]
#   [2]

TSort.each_strongly_connected_component(each_node, each_child) {|scc| p scc }

Array of the currently loaded libraries.

Returns the names of all available ciphers in an array.

returns the socket option name as an integer.

p Socket::Option.new(:INET6, :IPV6, :RECVPKTINFO, [1].pack("i!")).optname
#=> 2
