hacks/interface

class Module < Object

A hack to allow a mixin to be used like Java's "interfaces".

E.g.:

  module Foo
    interface_method :foo
    interface_method :bar
  end
  class XYZ
    def bar
    end
  end
  class Bar < XYZ
    def foo
      puts "foo"
  end
  b = Bar.new
  assert_object_includes_complete(b, Foo)
  b.foo
  b.bar

Public Methods

includes_module?(mod)

Determine if a class includes a module, in O(n) time.

Returns: true if the class includes the module, false otherwise.

Private Methods

interface_method(symbol)

Declare an abstract method.

symbol	the name of the method.

Public Methods

assert_class_includes(klass, mod)

Determine if a class includes a module, in O(n) time.

Returns: true if the class includes the module, false otherwise.

assert_object_includes(obj, mod)

Determine if an object's class includes a module, in O(n) time.

Returns: true if the object's class includes the module, false otherwise.

assert_class_includes_complete(klass, mod)

Determine if a class includes a module and implements all the module's abstract methods, in O(n+m) time.

Returns: true if the class includes the module, false otherwise.

assert_object_includes_complete(obj, mod)

Determine if an object's class includes a module and implements all the module's abstract methods, in O(n+m) time.

Returns: true if the object's class includes the module, false otherwise.
