public interface BufferProcessor
Interface called back when IO buffer draining or filling can actually be done.
Method Summary | |
---|---|
boolean |
canLoop(Buffer buffer,
Object... args)
Indicates if the processing loop can continue. |
boolean |
couldFill(Buffer buffer,
Object... args)
Indicates if the buffer could be filled again. |
int |
onDrain(Buffer buffer,
int maxDrained,
Object... args)
Drains the byte buffer. |
int |
onFill(Buffer buffer,
Object... args)
Fills the byte buffer. |
void |
onFillEof()
Called back when a fill operation returns with an EOF status. |
void |
postProcess(int drained)
Called back after a complete processing pass. |
int |
preProcess(int maxDrained,
Object... args)
Called back before a processing pass. |
