public class NioBlockingSelector
- extends java.lang.Object
Method Summary |
static int |
read(java.nio.ByteBuffer buf,
NioChannel socket,
long readTimeout)
Performs a blocking read using the bytebuffer for data to be read
If the selector parameter is null, then it will perform a busy read that could
take up a lot of CPU cycles. |
static int |
write(java.nio.ByteBuffer buf,
NioChannel socket,
long writeTimeout)
Performs a blocking write using the bytebuffer for data to be written
If the selector parameter is null, then it will perform a busy write that could
take up a lot of CPU cycles. |

NioBlockingSelector
public NioBlockingSelector()
write
public static int write(java.nio.ByteBuffer buf,
NioChannel socket,
long writeTimeout)
throws java.io.IOException
- Performs a blocking write using the bytebuffer for data to be written
If the
selector
parameter 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 towriteTimeout
- 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 static 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
selector
parameter 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 outsocket
- SocketChannel - the socket to write data toselector
- Selector - the selector to use for blocking, if null then a busy read will be initiatedreadTimeout
- 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
