public class Context : Object

JSCContext represents a JavaScript execution context, where all operations take place and where the values will be associated.

When a new context is created, a global object is allocated and the built-in JavaScript objects (Object, Function, String, Array) are populated. You can execute JavaScript in the context by using evaluate or evaluate_with_source_uri. It's also possible to register custom objects in the context with register_class.
