Interface RspFilter

public interface RspFilter
Interface defining when a group request is done. This allows for termination of a group request based on logic implemented by the caller. Example: caller uses mode GET_FIRST plus a RspFilter implementation. Here, the request will not return (assuming timeout is 0) when the first response has been received, but when the filter passed
