Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name, *args) ⇒ Object (private)

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Used for allowing accessor methods for dynamic attributes.

Examples:

Call through method_missing.

document.method_missing(:test)

Parameters:

  • name (String | Symbol) —

    The name of the method.

  • *args (Object...) —

    The arguments to the method.

Returns:

  • (Object) —

    The result of the method call.
