Hi,
before moving to FPWD I'd suggest to extend the subscription method with some basic filters. The rationale is that a generic subscription (e.g. on MessagingManager.EMAIL_TYPE) may generate a big number of callback invocations, forcing each application to implement its own filters.
My proposal for extending the subscribe method is:
int subscribe (in MessagingFilter filter, in OnIncomingMessage messageEventCB, in optional ErrorCallback errorCB);
interface MessagingFilter {
attribute unsigned short messagingType;
attribute DOMString from;
attribute DOMString to;
attribute DOMString body;
};
As you can see the basic use case (filtering on message type) is still supported, but it is now possible to receive callbacks only when a particular condition on sender and/or receiver and/or body is verified (eg. an email sent by "public-device-apis@w3.org").
