|  void | open(java.nio.channels.Selector selector)
 | 
|  int | read(java.nio.ByteBuffer buf,
     NioChannel socket,

 If the
 selectorparameter is null, then it will perform a busy read that could
 take up a lot of CPU cycles. |

write
public int write(java.nio.ByteBuffer buf,
                 NioChannel socket,
                 long writeTimeout,
                 MutableInteger lastWrite)
          throws java.io.IOException
- Performs a blocking write using the bytebuffer for data to be written
 If the selectorparameter is null, then it will perform a busy write that could
 take up a lot of CPU cycles.
 
- 
- Parameters:
- buf- ByteBuffer - the buffer containing the data, we will write as long as- (buf.hasRemaining()==true)
- socket- SocketChannel - the socket to write data to
- writeTimeout- long - the timeout for this write operation in milliseconds, -1 means no timeout
- Returns:
- int - returns the number of bytes written
- Throws:
- java.io.EOFException- if write returns -1
- java.net.SocketTimeoutException- if the write times out
- java.io.IOException- if an IO Exception occurs in the underlying socket logic
 
read
public int read(java.nio.ByteBuffer buf,
                NioChannel socket,
                long readTimeout)
         throws java.io.IOException
- Performs a blocking read using the bytebuffer for data to be read
 If the selectorparameter is null, then it will perform a busy read that could
 take up a lot of CPU cycles.
 
- 
- Parameters:
- buf- ByteBuffer - the buffer containing the data, we will read as until we have read at least one byte or we timed out
- socket- SocketChannel - the socket to write data to
- readTimeout- long - the timeout for this read operation in milliseconds, -1 means no timeout
- Returns:
- int - returns the number of bytes read
- Throws:
- java.io.EOFException- if read returns -1
- java.net.SocketTimeoutException- if the read times out
- java.io.IOException- if an IO Exception occurs in the underlying socket logic
