Interface ElvisHandler

All Known Implementing Classes:: ElvisTest.TestHandler

public interface ElvisHandler

ElvisHandler is the primitive interface for the handlers passed to ElvisHandler.get() . perform() will be called whenever the ElvisWatcher thread receives a request from an Elvis client.

Implementors of ElvisHandler must be aware that they are not being called from the Swing notification thread, and handle their UI interactions accordingly.

perform is not called in a thread-safe manner. If we are the One True Elvis, then it is quite possible for the local Elvis client to call perform from one of its threads at the same time as another Elvis client transmits a request to us. In this case, it we will wind up with two different threads in the perform method. Although Elvis is thread-safe up until the point of collision, it is up to the client application (that is, your code) to take over thread-safety, starting with the perform method.

Also, to avoid potentially blocking Elvis clients while the handler does work, implementors will probably want to have a separate thread for actually doing the work of the ElvisHandler. In this case, perform should simply queue the request and then return.
