Convert internal ID of token symbol to the string.
Creates a new Socket::Option
object for IP_MULTICAST_TTL.
The size is dependent on the platform.
p Socket::Option.ipv4_multicast_ttl(10) #=> #<Socket::Option: INET IP MULTICAST_TTL 10>
Returns the ipv4_multicast_ttl
data in sockopt as an integer.
sockopt = Socket::Option.ipv4_multicast_ttl(10) p sockopt.ipv4_multicast_ttl => 10
Creates a new Socket::Option
object for IP_MULTICAST_LOOP.
The size is dependent on the platform.
sockopt = Socket::Option.int(:INET, :IPPROTO_IP, :IP_MULTICAST_LOOP, 1) p sockopt.int => 1 p Socket::Option.ipv4_multicast_loop(10) #=> #<Socket::Option: INET IP MULTICAST_LOOP 10>
Returns the ipv4_multicast_loop
data in sockopt as an integer.
sockopt = Socket::Option.ipv4_multicast_loop(10) p sockopt.ipv4_multicast_loop => 10
Specification
attributes that must be non-nil
Expire memoized instance variables that can incorrectly generate, replace or miss files due changes in certain attributes used to compute them.
Creates a regular expression to match IPv4 addresses
Returns the inverse of the eigenvector matrix V
Opens a message writer stream and gives it to the block. The stream is valid only in the block, and has these methods:
outputs STR and CR LF.
outputs STR.
outputs sprintf(fmt,*args).
outputs STR and returns the length of written bytes.
outputs STR and returns self.
If a single CR (“r”) or LF (“n”) is found in the message, it is converted to the CR LF pair. You cannot send a binary message with this method.
from_addr
is a String
representing the source mail address.
to_addr
is a String
or Strings or Array
of Strings, representing the destination mail address or addresses.
Net::SMTP.start('smtp.example.com', 25) do |smtp| smtp.open_message_stream('from@example.com', ['dest@example.com']) do |f| f.puts 'From: from@example.com' f.puts 'To: dest@example.com' f.puts 'Subject: test message' f.puts f.puts 'This is a test message.' end end
This method may raise:
The get_attribute_ns
method retrieves a method by its namespace and name. Thus it is possible to reliably identify an attribute even if an XML
processor has changed the prefix.
