creates a socket connected to remote_addr_args and bound to self.
The optional last argument opts is options represented by a hash. opts may have following options:
specify the timeout in seconds.
If a block is given, it is called with the socket and the value of the block is returned. The socket is returned otherwise.
Addrinfo.tcp("0.0.0.0", 4649).connect_to("www.ruby-lang.org", 80) {|s| s.print "GET / HTTP/1.0\r\nHost: www.ruby-lang.org\r\n\r\n" puts s.read }
Returns self.
Returns a Hash containing all name/value pairs from ENV:
ENV.replace('foo' => '0', 'bar' => '1') ENV.to_hash # => {"bar"=>"1", "foo"=>"0"}
Returns an IO object representing the current file. This will be a File object unless the current file is a stream such as STDIN.
For example:
ARGF.to_io #=> #<File:glark.txt> ARGF.to_io #=> #<IO:<STDIN>>
Returns a string containing the IP address representation in canonical form.
Creates a Range object for the network address.
Makes a set from the enumerable object with given arguments. Needs to require "set" to use this method.
Dump Ruby object to a JSON string.
Convert a reference into an object using the current server.
This raises a DRbServerNotFound error if there is no current server. See current_server.
Get a reference id for an object using the current server.
This raises a DRbServerNotFound error if there is no current server. See current_server.

This raises a DRbServerNotFound error if there is no current server. See current_server.

Response class for Switching Protocol responses (status code 101).
The <tt>Switching Protocol<tt> response indicates that the server has received a request to switch protocols, and has agreed to do so.

Module managing the underlying network protocol(s) used by drb.
By default, drb uses the DRbTCPSocket protocol. Other protocols can be defined. A protocol must define the following class methods:
[open(uri, config)] Open a client connection to the server at +uri+,
using configuration +config+. Return a protocol
instance for this connection.
[open_server(uri, config)] Open a server listening at +uri+,
using configuration +config+. Return a
protocol instance for this listener.
[uri_option(uri, config)] Take a URI, possibly containing an option
component (e.g. a trailing '?param=val'),
and return a [uri, option] tuple.
All of these methods should raise a DRbBadScheme error if the URI does not identify the protocol they support (e.g. “druby:” for the standard Ruby protocol). This is how the DRbProtocol module, given a URI, determines which protocol implementation serves that protocol.
The protocol instance returned by open_server must have the following methods:
Accept a new connection to the server. Returns a protocol instance capable of communicating with the client.
Close the server connection.
Get the URI for this server.
The protocol instance returned by open must have the following methods:
Send a request to ref with the given message id and arguments. This is most easily implemented by calling DRbMessage.send_request, providing a stream that sits on top of the current protocol.
Receive a reply from the server and return it as a [success-boolean, reply-value] pair. This is most easily implemented by calling DRb.recv_reply, providing a stream that sits on top of the current protocol.
Is this connection still alive?
Close this connection.
The protocol instance returned by open_server().accept() must have the following methods:
Receive a request from the client and return a [object, message, args, block] tuple. This is most easily implemented by calling DRbMessage.recv_request, providing a stream that sits on top of the current protocol.
Send a reply to the client. This is most easily implemented by calling DRbMessage.send_reply, providing a stream that sits on top of the current protocol.
Close this connection.
A new protocol is registered with the DRbProtocol module using the add_protocol method.
For examples of other protocols, see DRbUNIXSocket in drb/unix.rb, and HTTP0 in sample/http0.rb and sample/http0serv.rb in the full drb distribution.
