Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method_name, *_args) ⇒ Object

Necessary overload of the method_missing method to allow for direct access to dynamic attributes without changing the user usage too much. Returns the corresponding attribute when asked.

Otherwise, raises a NoMethodError.

Parameters:

  • method_name (Symbol) —

    The name of the method being called.

  • _args (Array) —

    Arguments passed to the method.

Returns:

  • (Object) —

    The value associated with the method name in @all_values.

Instance Method Details

#respond_to_missing?(method_name, include_private = false) ⇒ bool

Necessary overload of the respond_to_missing? method to allow for direct access to dynamic attributes without changing the user usage too much. Returns true if the method name exists as a key in @all_values, indicating that the object can respond to the method. Otherwise, calls super to fallback to the default behavior.

Parameters:

  • method_name (Symbol) —

    The name of the method being checked.

  • include_private (bool) (defaults to: false) —

    Whether to include private methods in the check.

Returns:

  • (bool) —

    True if the method can be responded to, false otherwise.
