- Method Detail
  - onFlushed
```
void onFlushed(long bytes)
        throws java.io.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:
    
    java.io.IOException - if the write should fail
