ChannelConfig
sub-type which offers extra methods which are useful for NIO.Modifier and Type | Method and Description |
---|---|
int |
getWriteBufferHighWaterMark()
Returns the high water mark of the write buffer.
|
int |
getWriteBufferLowWaterMark()
Returns the low water mark of the write buffer.
|
int |
getWriteSpinCount()
Returns the maximum loop count for a write operation until
WritableByteChannel.write(ByteBuffer) returns a non-zero value. |
void |
setWriteBufferHighWaterMark(int writeBufferHighWaterMark)
Sets the high water mark of the write buffer.
|
void |
setWriteBufferLowWaterMark(int writeBufferLowWaterMark)
Sets the low water mark of the write buffer.
|
void |
setWriteSpinCount(int writeSpinCount)
Sets the maximum loop count for a write operation until

WritableByteChannel.write(ByteBuffer)
returns a non-zero value.
It is similar to what a spin lock is used for in concurrency programming.
It improves memory utilization and write throughput depending on
the platform that JVM runs on. The default value is 16
