public void consume(ByteBuffer src)
             throws IOException
```
    从接口复制的说明: AsyncDataConsumer
    
    Triggered to pass incoming data to the data consumer. The consumer must consume the entire content of the data buffer. The consumer must stop incrementing its capacity on the capacity channel if it is unable to accept more data. Once the data consumer has handled accumulated data or allocated more intermediate storage it can update its capacity information on the capacity channel.
    
    指定者:
    
    consume 在接口中 AsyncDataConsumer
    
    参数:
    
    src - data source.
