Returns the destination encoding name as a string.

Returns the destination encoding name as a string.

Sets the encoding to be used for the response body; returns the encoding.

The given value may be:

• An Encoding object.

• The name of an encoding.

• An alias for an encoding name.

See Encoding.

Examples:

http = Net::HTTP.new(hostname)
http.response_body_encoding = Encoding::US_ASCII # => #<Encoding:US-ASCII>
http.response_body_encoding = 'US-ASCII'         # => "US-ASCII"
http.response_body_encoding = 'ASCII'            # => "ASCII"

Clear recorded tracing information.

Returns an array of the names of singleton methods for obj. If the optional all parameter is true, the list will include methods in modules included in obj. Only public and protected singleton methods are returned.

module Other
  def three() end
end

class Single
  def Single.four() end
end

a = Single.new

def a.one()
end

class << a
  include Other
  def two()
  end
end

Single.singleton_methods    #=> [:four]
a.singleton_methods(false)  #=> [:two, :one]
a.singleton_methods         #=> [:two, :one, :three]

Similar to method, searches singleton method only.

class Demo
  def initialize(n)
    @iv = n
  end
  def hello()
    "Hello, @iv = #{@iv}"
  end
end

k = Demo.new(99)
def k.hi
  "Hi, @iv = #{@iv}"
end
m = k.singleton_method(:hi)
m.call   #=> "Hi, @iv = 99"
m = k.singleton_method(:hello) #=> NameError

Returns an array of the string method names of the methods that accept the given keyword option opt; the argument must be a symbol:

FileUtils.collect_method(:preserve) # => ["cp", "copy", "cp_r", "install"]

Invoked as a callback whenever a singleton method is removed from the receiver.

module Chatty
  def Chatty.singleton_method_removed(id)
    puts "Removing #{id.id2name}"
  end
  def self.one()     end
  def two()          end
  def Chatty.three() end
  class << self
    remove_method :three
    remove_method :one
  end
end

produces:

Removing three
Removing one

Calls the block, if given, with each element of self; returns a new Array whose elements are the return values from the block:

a = [:foo, 'bar', 2]
a1 = a.map {|element| element.class }
a1 # => [Symbol, String, Integer]

Returns a new Enumerator if no block given:

a = [:foo, 'bar', 2]
a1 = a.map
a1 # => #<Enumerator: [:foo, "bar", 2]:map>

Calls the block, if given, with each element; replaces the element with the block’s return value:

a = [:foo, 'bar', 2]
a.map! { |element| element.class } # => [Symbol, String, Integer]

Returns a new Enumerator if no block given:

a = [:foo, 'bar', 2]
a1 = a.map!
a1 # => #<Enumerator: [:foo, "bar", 2]:map!>

Calls the block, if given, with each element of self; returns a new Array containing those elements of self for which the block returns a truthy value:

a = [:foo, 'bar', 2, :bam]
a1 = a.select {|element| element.to_s.start_with?('b') }
a1 # => ["bar", :bam]

Returns a new Enumerator if no block given:

a = [:foo, 'bar', 2, :bam]
a.select # => #<Enumerator: [:foo, "bar", 2, :bam]:select>
