method invocation services and converted everything to the new style. Could this be my biggest checkin ever? git-svn-id: svn+ssh://src.earth.threerings.net/narya/trunk@1642 542714f4-19e9-0310-aa3c-eee0fc999fb1

/**
|
|
* Serves as the base interface for invocation services. An invocation
|
|
* service can be defined by extending this interface and defining service
|
|
* methods, as well as response listeners (which must extend {@link
|
|
* InvocationListener}). For example:
|
|
*
|
|
* <pre>
|
|
* public interface LocationService extends InvocationService
|
|
* {
|
|
*
|
|
* // Used to communicate responses to moveTo() requests.
|
|
* public interface MoveListener extends InvocationListener
|
|
* {
|
|
* // Called in response to a successful moveTo() request.
|
|
* public void moveSucceeded (PlaceConfig config);
|
|
* }
|
|
*
|
|
* // Requests that this client's body be moved to the specified
|
|
* // location.
|
|
* //
|
|
* // @param placeId the object id of the place object to which the
|
|
* // body should be moved.
|
|
* // @param listener the listener that will be informed of success or
|
|
* // failure.
|
|
* public void moveTo (int placeId, MoveListener listener);
|
|
* }
|
|
* </pre>
|
|
*
|
|
* From this interface, a <code>LocationProvider</code> interface will be
|
|
* generated which should be implemented by whatever server entity that
|
|
* will actually provide the server side of this invocation service. That
|
|
* provider interface would look like the following:
|
|
*
|
|
* <pre>
|
|
* public interface LocationProvider extends InvocationProvider
|
|
* {
|
|
* // Requests that this client's body be moved to the specified
|
|
* // location.
|
|
* //
|
|
* // @param caller the client object of the client that invoked this
|
|
* // remotely callable method.
|
|
* // @param placeId the object id of the place object to which the
|
|
* // body should be moved.
|
|
* // @param listener the listener that should be informed of success
|
|
* // or failure.
|
|
* public void moveTo (ClientObject caller, int placeId,
|
|
* MoveListener listener)
|
|
* throws InvocationException;
|
|
* }
|
|
* </pre>
|

/**
|
|
* Invocation service methods that require a response should take a
|
|
* listener argument that can be notified of request success or
|
|
* failure. The listener argument should extend this interface so that
|
|
* generic failure can be reported in all cases. For example:
|
|
*
|
|
* <pre>
|
|
* // Used to communicate responses to <code>moveTo</code> requests.
|
|
* public interface MoveListener extends InvocationListener
|
|
* {

* // Called in response to a successful <code>moveTo</code>
