Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name, *args, &block) ⇒ Object (protected)

Default behavior of method missing should be to delegate all calls to the target of the proxy. This can be overridden in special cases.

Parameters:

  • name (String, Symbol) —

    The name of the method.

  • *args (Array) —

    The arguments passed to the method.
