    • Method Detail

      • 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 return false.
      • 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 return false.
      • 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 return true 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 toreturn true again.
      • getWriteSpinCount

        int getWriteSpinCount()
        Returns 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.
      • setWriteSpinCount

        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.
        Throws:
        java.lang.IllegalArgumentException - if the specified value is 0 or less than 0
