Package orc.orchard Description

Orchard is the service-oriented implementation of Orc. This package consists of:

• Interfaces for services. These exist primarily for documentation, although they are used to typecheck implementations as much as possible.
• Value types used for service method arguments. Ideally, the implementations of these would be provided by the binding, but Java's type system and reflection don't accomodate that very well.
• Abstract implementations of services which contain all the non-binding-specific logic.
• Concrete bindings of services (in sub-packages).
• Exceptions.

Some conventions used by the interfaces:

• Service methods should throw RemoteException to indicate a protocol error
• In order to accomodate a variety of bindings, method names should be unique (overloading is not allowed)
• Data classes must extend Serializable
• Data members are represented by bean properties
