Buffer.capacity介绍

[英]Returns the capacity of this buffer. If underlying data is backed by ByteBuffer, capacity is the difference between limit and initial position of the backing ByteBuffer. For String backed buffer, capacity is the string length.
[中]返回此缓冲区的容量。如果基础数据由ByteBuffer支持，则容量是支持ByteBuffer的限制和初始位置之间的差值。对于支持字符串的缓冲区，容量是字符串长度。

static void  copy(Buffer srcBuffer, Buffer destBuffer)
{
  ByteBuffer destByteBuffer = destBuffer.data();
  int srcBufferlength = srcBuffer.length();
  
  if ( destByteBuffer == null || destBuffer.capacity()  < srcBufferlength)
    destByteBuffer = ByteBuffer.allocate(srcBufferlength);
  else
    destByteBuffer.clear();
  ByteBuffer srcByteBuffer = srcBuffer.data();
  int limit = srcBuffer.position() + srcBuffer.length();	
  for (int index =  srcBuffer.position(); index < limit; ++index)
    destByteBuffer.put(srcByteBuffer.get(index));
  
  destByteBuffer.flip();
  
  destBuffer.data(destByteBuffer);
