Method Details

getWriteBufferHighWaterMark
int getWriteBufferHighWaterMark()Returns the high water mark of the write buffer. If the number of bytes queued in the write buffer exceeds this value,Channel.isWritable()
will start to returnfalse
. -
setWriteBufferHighWaterMark
void setWriteBufferHighWaterMark(int writeBufferHighWaterMark) Sets the high water mark of the write buffer. If the number of bytes queued in the write buffer exceeds this value,Channel.isWritable()
will start to returnfalse
. -
getWriteBufferLowWaterMark
int getWriteBufferLowWaterMark()Returns the low water mark of the write buffer. Once the number of bytes queued in the write buffer exceeded the high water mark and then dropped down below this value,Channel.isWritable()
will start to returntrue
again. -
setWriteBufferLowWaterMark
void setWriteBufferLowWaterMark(int writeBufferLowWaterMark) Sets the low water mark of the write buffer. Once the number of bytes queued in the write buffer exceeded the high water mark and then dropped down below this value,Channel.isWritable()
will start toreturntrue
again. -
getWriteSpinCount
int getWriteSpinCount()Returns the maximum loop count for a write operation untilWritableByteChannel.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 is16

setWriteSpinCount
void setWriteSpinCount(int writeSpinCount) Sets the maximum loop count for a write operation untilWritableByteChannel.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 is16
.- Throws:
IllegalArgumentException
- if the specified value is0
or less than0
