从Bytes<ByteBuffer>检索ByteBuffer对象

Question

我一直在尝试从字节对象中检索ByteBuffer (直接)对象引用。代码如下：

TestMessageWire testMessageWire = new TestMessageWire();
testMessageWire.data('H');
testMessageWire.setIntData(100);

//Below does not give ByteBuffer with correct position & offset
Bytes<ByteBuffer> bytes = Bytes.elasticByteBuffer(10);
Wire wire = new RawWire(bytes);
testMessageWire.writeMarshallable(wire);
ByteBuffer byteBuffer = ByteBuffer.wrap(bytes.toByteArray());

//Another approach, but still does not populate "byteBuffer" object correctly.
ByteBuffer byteBuffer = ByteBuffer.allocateDirect(6);
Bytes<?> bytes = Bytes.wrapForWrite(byteBuffer);
Wire wire = new RawWire(bytes);
testMessageWire.writeMarshallable(wire);

我希望在创建ByteBuffer对象时避免多次分配。因此，希望重用由Bytes包装的相同Bitebuffer。我如何才能做到这一点？
