void onFlushed(long bytes) throws java.io.IOException
Invoked when a
WriteFlusherflushed bytes in a non-blocking way, as part of a - possibly larger - write.
This method may be invoked multiple times, for example when writing a large buffer: a first flush of bytes, then the connection became TCP congested, and a subsequent flush of bytes when the connection became writable again.
This method is never invoked concurrently, but may be invoked by different threads, so implementations may not rely on thread-local variables.
Implementations may throw an
IOExceptionto signal that the write should fail, for example if the implementation enforces a minimum data rate.
bytes- the number of bytes flushed
java.io.IOException- if the write should fail
