Backend API. Server-side code: this runs in a Codename One backend, not in the app on the device.

public interface Handler

What a Lambda-style handler implements. The event and the return value are raw JSON strings at this layer; the generated dispatcher from a @RestClient interface is what turns them into typed calls.

Methods

public abstract

String handle(String event, String requestId)
throws Exception

event: the invocation payload, as JSON - requestId: the host runtime’s id for this invocation, for correlating logs
