Package org.cristalise.kernel.entity Description

The implementations of Items, and their core functionality.

The CORBA IDLs generate the Item and Agent interfaces and their support classes in this package. In the kernel source tree, the classes TraceableEntity and ItemImplementation provides the implementing object for the Item on the server side, while the Locator class, plus the CorbaServer handle instantiation and caching of Items (and Agents) on the server.

The corresponding implementation for Agents is located in the agent sub-package.

Also in this package is the C2KLocalObject interface, which is implemented by all objects that may be stored in the CRISTAL persistency mechanism.
