Results for: "to_proc"

Generates a radio-button Input element.

name is the name of the input field. value is the value of the field if checked. checked specifies whether the field starts off checked.

Alternatively, the attributes can be specified as a hash.

radio_button("name", "value")
  # <INPUT TYPE="radio" NAME="name" VALUE="value">

radio_button("name", "value", true)
  # <INPUT TYPE="radio" NAME="name" VALUE="value" CHECKED>

radio_button("NAME" => "name", "VALUE" => "value", "ID" => "foo")
  # <INPUT TYPE="radio" NAME="name" VALUE="value" ID="foo">

@return [Array<Vertex>] the vertices of {#graph} where ‘self` is a

{#descendent?}

@param [String] name @return [Vertex,nil] the root vertex with the given name

Returns the generator of the group.

Returns the cofactor of the group.

Is this tar entry a directory?

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!"

Returns true when OLE object has OLE method, otherwise returns false.

ie = WIN32OLE.new('InternetExplorer.Application')
ie.ole_respond_to?("gohome") => true

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:

Adding singleton_method_added
Adding one
Adding three

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

Invoked as a callback whenever a singleton method is undefined in the receiver.

module Chatty
  def Chatty.singleton_method_undefined(id)
    puts "Undefining #{id.id2name}"
  end
  def Chatty.one()   end
  class << self
     undef_method(:one)
  end
end

produces:

Undefining one

Shortcut for defining multiple delegator methods, but with no provision for using a different name. The following two code samples have the same effect:

def_delegators :@records, :size, :<<, :map

def_delegator :@records, :size
def_delegator :@records, :<<
def_delegator :@records, :map

Define method as delegator instance method with an optional alias name ali. Method calls to ali will be delegated to accessor.method.

class MyQueue
  extend Forwardable
  attr_reader :queue
  def initialize
    @queue = []
  end

  def_delegator :@queue, :push, :mypush
end

q = MyQueue.new
q.mypush 42
q.queue    #=> [42]
q.push 23  #=> NoMethodError

Shortcut for defining multiple delegator methods, but with no provision for using a different name. The following two code samples have the same effect:

def_delegators :@records, :size, :<<, :map

def_delegator :@records, :size
def_delegator :@records, :<<
def_delegator :@records, :map

Defines a method method which delegates to accessor (i.e. it calls the method of the same name in accessor). If new_name is provided, it is used as the name for the delegate method.

Quietly ensure the Gem directory dir contains all the proper subdirectories. If we can’t create a directory due to a permission problem, then we will silently continue.

If mode is given, missing directories are created with this mode.

World-writable directories will never be created.
