Boolean negate.

Returns true if two objects are not-equal, otherwise false.

Equality—At the Object level, == returns true only if obj and other are the same object. Typically, this method is overridden in descendent classes to provide class-specific meaning.

Unlike ==, the equal? method should never be overridden by subclasses: it is used to determine object identity (that is, a.equal?(b) iff a is the same object as b).

The eql? method returns true if obj and anObject have the same value. Used by Hash to test members for equality. For objects of class Object, eql? is synonymous with ==. Subclasses normally continue this tradition, but there are exceptions. Numeric types, for example, perform type conversion across ==, but not across eql?, so:

   1 == 1.0     #=> true
   1.eql? 1.0   #=> false

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
