public interface Interceptor<R> { int DEFAULT = 0; int COMPLETED = 1; int INCOMPLETED = 2; int RESET = 4;
Callback method is called by Readable, so it is possible to customize reading process. Mostly Interceptor is used to control asynchronous reads.
Params:
  • event – type of intercepted event.
  • context – read operation context.
  • result – last read operation result.
Returns:the implementation specific code to instruct Readable how it should continue reading operation.
