    public interface GroovyObject

The interface implemented by all Groovy objects.

Especially handy for using Groovy objects when in the Java world.

- ## Method Summary

  Modifier and Type | Method | Description
  --- | --- | ---
  `MetaClass` | `getMetaClass()` | Returns the metaclass for a given class.

  `default Object` | `invokeMethod​(String name, Object args)` | Invokes the given method.
  `void` | `setMetaClass​(MetaClass metaClass)` | Allows the MetaClass to be replaced with a derived implementation.
  `default void` | `setProperty​(String propertyName, Object newValue)` | Sets the given property to the new value.
