Public Instance methods

__proxy_loaded__()

Helper method that indicates if the proxy has loaded the original method results yet.

[Source]

    # File lib/lazy_methods.rb, line 71
71:     def __proxy_loaded__
72:       !!defined?(@proxy_result)
73:     end

__proxy_result__()

Get the result of the original method call. The original method will only be called once.

[Source]

    # File lib/lazy_methods.rb, line 65
65:     def __proxy_result__
66:       @proxy_result = @object.send(@method, *@args, &@block) unless defined?(@proxy_result)
67:       @proxy_result
68:     end

method_missing(method, *args, &block)

All missing methods are proxied to the original result object.

[Source]

    # File lib/lazy_methods.rb, line 76
76:     def method_missing (method, *args, &block)
77:       __proxy_result__.send(method, *args, &block)
