Class VelocityContext

public class VelocityContext extends AbstractContext implements Cloneable

General purpose implemention of the application Context interface for general application use. This class should be used in place of the original Context class. This implementation uses a HashMap (@see java.util.HashMap ) for data storage. This context implementation cannot be shared between threads without those threads synchronizing access between them, as the HashMap is not synchronized, nor are some of the fundamentals of AbstractContext. If you need to share a Context between threads with simultaneous access for some reason, please create your own and extend the interface Context
