### Question:
Serializer { public abstract <T> T readObject(final InputBuf inputBuf, final Class<T> clazz);  abstract OutputBuf writeObject(final OutputBuf outputBuf, final T obj); abstract byte[] writeObject(final T obj); abstract T readObject(final InputBuf inputBuf, final Class<T> clazz); abstract T readObject(final ByteBuffer buf, final Class<T> clazz); abstract T readObject(final byte[] bytes, final int offset, final int length, final Class<T> clazz); T readObject(final byte[] bytes, final Class<T> clazz); static final int MAX_CACHED_BUF_SIZE; static final int DEFAULT_BUF_SIZE; }### Answer:
@Test public void readObjectTest() { final Serializer serializer = Serializers.getDefault(); final KVOperation op = KVOperation.createPut(BytesUtil.writeUtf8("key"), BytesUtil.writeUtf8("value")); final byte[] bytes = serializer.writeObject(op); final ByteBuffer buffer = ByteBuffer.allocateDirect(bytes.length); buffer.put(bytes); buffer.flip(); final KVOperation op1 = serializer.readObject(bytes, KVOperation.class); final KVOperation op2 = serializer.readObject(buffer, KVOperation.class); assertArrayEquals(op1.getKey(), op.getKey()); assertArrayEquals(op1.getValue(), op.getValue()); assertEquals(op.getOp(), op.getOp()); assertArrayEquals(op1.getKey(), op2.getKey()); assertArrayEquals(op1.getValue(), op2.getValue()); assertEquals(op.getOp(), op2.getOp()); }
