Interface UserFactory

All Known Implementing Classes:

DeviceEphemeralUserFactory, DevicePersistentUserFactory

public interface UserFactory

Interface implemented by objects that can produce User objects on demand, either by manufacturing them from whole cloth or by fetching information from an external data store. Such factory objects are typically singletons stored in the contextor's static object table. These factories are used in conjuction with the user synthesis entry pattern provided by the Session object's extercontext() method.

Method Detail

provideUser

void provideUser(Contextor contextor,
               Connection connection,
               JSONObject param,
               ArgRunnable handler)

Produce a user object.

Parameters:

contextor - The contextor of the server in which the requested user will be present

connection - The connection over which the new user presented themself.

param - Arbitary JSON object parameterizing the construction. this is analogous to the user record read from the ODB, but may be anything that makes sense for the particular factory implementation. Of course, the sender of this parameter must be coordinated with the factory implementation.

handler - Handler to be called with the result. The result will be the user object that was produced, or null if none could be.
