The encodings are downcased for canonicalization.

The current session cache mode.

Sets the SSL session cache mode. Bitwise-or together the desired SESSION_CACHE_* constants to set. See SSL_CTX_set_session_cache_mode(3) for details.

Removes the named instance variable from obj, returning that variable’s value.

class Dummy
  attr_reader :var
  def initialize
    @var = 99
  end
  def remove
    remove_instance_variable(:@var)
  end
end
d = Dummy.new
d.var      #=> 99
d.remove   #=> 99
d.var      #=> nil

Defines a singleton method in the receiver. The method parameter can be a Proc, a Method or an UnboundMethod object. If a block is specified, it is used as the method body.

class A
  class << self
    def class_name
      to_s
    end
  end
end
A.define_singleton_method(:who_am_i) do
  "I am: #{class_name}"
end
A.who_am_i   # ==> "I am: A"

guy = "Bob"
guy.define_singleton_method(:hello) { "#{self}: Hello there!" }
guy.hello    #=>  "Bob: Hello there!"

Execute the provided block, but preserve the rounding mode

BigDecimal.save_rounding_mode do
  BigDecimal.mode(BigDecimal::ROUND_MODE, :up)
  puts BigDecimal.mode(BigDecimal::ROUND_MODE)
end

For use with the BigDecimal::ROUND_*

See BigDecimal.mode

Invoked as a callback whenever a singleton method is added to the receiver.

module Chatty
  def Chatty.singleton_method_added(id)
    puts "Adding #{id.id2name}"
  end
  def self.one()     end
  def two()          end
  def Chatty.three() end
end

produces:

Specifies VI editing mode. See the manual of GNU Readline for details of VI editing mode.

Raises NotImplementedError if the using readline library does not support.

Returns true if vi mode is active. Returns false if not.

Raises NotImplementedError if the using readline library does not support.

Returns reference counter of Dispatch interface of WIN32OLE object. You should not use this method because this method exists only for debugging WIN32OLE.

Counts objects for each T_IMEMO type.

This method is only for MRI developers interested in performance and memory usage of Ruby programs.

It returns a hash as:

{:imemo_ifunc=>8,
 :imemo_svar=>7,
 :imemo_cref=>509,
 :imemo_memo=>1,
 :imemo_throw_data=>1}

If the optional argument, result_hash, is given, it is overwritten and returned. This is intended to avoid probe effect.

The contents of the returned hash is implementation specific and may change in the future.

In this version, keys are symbol objects.

This method is only expected to work with C Ruby.

Add the –prerelease option to the option parser.

Sends a SELECT command to select a mailbox so that messages in the mailbox can be accessed.

After you have selected a mailbox, you may retrieve the number of items in that mailbox from @responses[-1], and the number of recent messages from @responses[-1]. Note that these values can change if new messages arrive during a session; see add_response_handler() for a way of detecting this event.

A Net::IMAP::NoResponseError is raised if the mailbox does not exist or is for some reason non-selectable.

@return the XMLDecl encoding of this document as an Encoding object. If no XMLDecl has been set, returns the default encoding.
