Method

voidcopy(ByteBuffer src, ByteBuffer dst, int length)
copy 
int srcLimit = src.limit();
int dstLimit = dst.limit();
src.limit(src.position() + length);
dst.limit(dst.position() + length);
dst.put(src);
src.limit(srcLimit);
dst.limit(dstLimit);
voidcopy(ByteBuffer src, int srcStartindex, ByteBuffer dest, int destStartIndex, int length)
copy 
System.arraycopy(src.array(), srcStartindex, dest.array(), destStartIndex, length);
ByteBuffercopy(ByteBuffer src, int startindex, int endindex)
copy 
int size = endindex - startindex;
ByteBuffer ret = ByteBuffer.allocate(size);
src.position(startindex);
for (int i = 0; i < size; i++) {
    ret.put(src.get());
return ret;
intcopy(final ByteBuffer from, final ByteBuffer to)
copy 
final int len = from.limit();
return copy(from, 0, to, 0, len);
voidcopy2Buffer(byte[] src, int srcOff, int srcLen, ByteBuffer dst, int dstOff)
copy Buffer 
dst.reset(); 
dst.position(dst.position() + dstOff);
dst.put(src, srcOff, srcLen);
dst.reset();
ByteBuffercopyBinary(final ByteBuffer orig)
copy Binary 
if (orig == null) {
    return null;
ByteBuffer copy = ByteBuffer.wrap(new byte[orig.remaining()]);
if (orig.hasArray()) {
    System.arraycopy(orig.array(), orig.arrayOffset() + orig.position(), copy.array(), 0, orig.remaining());
} else {
    orig.slice().get(copy.array());
...
voidcopyBuffer(ByteBuffer dest, int pos1, ByteBuffer src, int len)
copy Buffer 
Objects.requireNonNull(dest);
Objects.requireNonNull(src);
if (pos1 >= 0 && len >= 0) {
    for (int i = 0; i < len && src.hasRemaining(); ++i)
        dest.put(pos1 + i, src.get());
voidcopyBufferToStream(OutputStream out, ByteBuffer in, int offset, int length)
Copy data from a buffer to an output stream. 
if (in.hasArray()) {
    out.write(in.array(), in.arrayOffset() + offset, length);
} else {
    for (int i = 0; i < length; ++i) {
        out.write(in.get(offset + i));
ByteBuffercopyByteBuffer(ByteBuffer buf)
copy Byte Buffer 
ByteBuffer dest = newByteBuffer(buf.remaining());
buf.mark();
dest.put(buf);
buf.reset();
dest.rewind();
return dest;
ByteBuffercopyByteBuffer(ByteBuffer src)
Make a copy of an existing buffer (src) to a new buffer (dest) 
ByteBuffer dest = newByteBuffer(src.capacity());
src.rewind();
dest.put(src);
return dest;
