Method Details

onFlushed

void onFlushed(long bytes)
        throws IOException

Invoked when a WriteFlusher flushed 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 IOException to signal that the write should fail, for example if the implementation enforces a minimum data rate.

Parameters:

bytes - the number of bytes flushed

Throws:

IOException - if the write should fail
