# File lib/rspec/mocks/instance_method_stasher.rb, line 109 def method_owned_by_klass? owner = @klass.instance_method(@method).owner # On Ruby 2.0.0+ the owner of a method on a class which has been # `prepend`ed may actually be an instance, e.g. # `#<MyClass:0x007fbb94e3cd10>`, rather than the expected `MyClass`. owner = owner.class unless Module === owner # On some 1.9s (e.g. rubinius) aliased methods # can report the wrong owner. Example: # class MyClass # class << self # alias alternate_new new # end # end # # MyClass.owner(:alternate_new) returns `Class` when incorrect, # but we need to consider the owner to be `MyClass` because # it is not actually available on `Class` but is on `MyClass`. # Hence, we verify that the owner actually has the method defined. # If the given owner does not have the method defined, we assume # that the method is actually owned by @klass. # # On 1.8, aliased methods can also report the wrong owner. Example: # module M # def a; end # module_function :a # alias b a # module_function :b # end # The owner of M.b is the raw Module object, instead of the expected # singleton class of the module return true if RUBY_VERSION < '1.9' && owner == @object owner == @klass || !(method_defined_on_klass?(owner)) end
