use of com.alibaba.nacos.core.distributed.raft.utils.FailoverClosure in project nacos by alibaba.

the class JRaftServer method applyOperation.

public void applyOperation(Node node, Message data, FailoverClosure closure) {
    final Task task = new Task();
    task.setDone(new NacosClosure(data, status -> {
        NacosClosure.NacosStatus nacosStatus = (NacosClosure.NacosStatus) status;
        closure.setThrowable(nacosStatus.getThrowable());
        closure.setResponse(nacosStatus.getResponse());
        closure.run(nacosStatus);
    }));
    // add request type field at the head of task data.
    byte[] requestTypeFieldBytes = new byte[2];
    requestTypeFieldBytes[0] = ProtoMessageUtil.REQUEST_TYPE_FIELD_TAG;
    if (data instanceof ReadRequest) {
        requestTypeFieldBytes[1] = ProtoMessageUtil.REQUEST_TYPE_READ;
    } else {
        requestTypeFieldBytes[1] = ProtoMessageUtil.REQUEST_TYPE_WRITE;
    }
    byte[] dataBytes = data.toByteArray();
    task.setData((ByteBuffer) ByteBuffer.allocate(requestTypeFieldBytes.length + dataBytes.length).put(requestTypeFieldBytes).put(dataBytes).position(0));
    node.apply(task);
