Represents a method on an object that may or may not be defined. The method may be an instance method on a module or a method on any object.

Public Instance Methods

defined?() click to toggle source

A method is defined if we are able to get a `Method` object for it. In that case, we can assert against metadata like the arity.

# File lib/rspec/mocks/method_reference.rb, line 46
def defined?
  @object_reference.when_loaded do |m|
    method_defined?(m)
  end
end

implemented?() click to toggle source

A method is implemented if sending the message does not result in a `NoMethodError`. It might be dynamically implemented by `method_missing`.

# File lib/rspec/mocks/method_reference.rb, line 23
def implemented?
  @object_reference.when_loaded do |m|
    method_implemented?(m)
  end
end

unimplemented?() click to toggle source

Returns true if we definitively know that sending the method will result in a `NoMethodError`.

This is not simply the inverse of `implemented?`: there are cases when we don’t know if a method is implemented and both `implemented?` and `unimplemented?` will return false.

# File lib/rspec/mocks/method_reference.rb, line 35
def unimplemented?
  @object_reference.when_loaded do |_m|
    return !implemented?
  end

  # If it's not loaded, then it may be implemented but we can't check.
  false
end

  @object_reference.when_loaded do |m|
    return visibility_from(m)
  end

  # When it's not loaded, assume it's public. We don't want to
  # wrongly treat the method as private.
