<b>CGraph</b> is a cross-platform <b>D</b>irected <b>A</b>cyclic <b>G</b>raph framework based on pure C++ without any 3rd-party dependencies.</br></br> You, with it, can <b>build your own operators simply, and describe any running schedules</b> as you need, such as dependence, parallelling, aggregation and so on. Some useful tools and plugins are also provide to improve your project.</br></br> Tutorials and contact information are show as follows.

一. 简介

CGraph中文名为【色丶图】，是一套无任何第三方依赖的跨平台图流程执行框架。通过GPipeline(流水线)底层调度，提供了包含依赖元素依次执行、非依赖元素并发执行在 eDAG 调度功能。

使用者只需继承GNode(节点)类，实现子类的run()方法，并根据需要设定依赖关系，即可实现任务的图化执行或流水线执行。还可以通过设定各种包含多节点信息的GGroup(组)，自行控制图的条件判断、循环和并发执行逻辑。

项目提供了丰富的Param(参数)类型，用于不同应用场景下的数据互通。此外，还可以通过添加GAspect(切面)的方式，实现以上各种元素功能的横向扩展；通过引入GAdapter(适配器)对单个节点功能进行加强；或者通过添加GEvent(信号)，丰富和优化执行逻辑。

CGraph Skeleton <br>

本工程使用纯C++11标准库编写，无任何第三方依赖。兼容MacOS、Linux、Windows和Android系统，支持通过 CLion、VSCode、Xcode、Visual Studio、Code::Blocks、Qt Creator等多款IDE进行本地编译和二次开发，具体编译方式请参考 CGraph 编译说明 <br>

详细功能介绍和用法，请参考 一面之猿网 中的文章内容。相关视频在B站持续更新中，欢迎观看和交流：<br>

二. 使用Demo

MyNode.h

#include "CGraph.h"

class MyNode1 : public CGraph::GNode {
public:
    CStatus run() override {
        printf("[%s], sleep for 1 second ...\n", this->getName().c_str());
        CGRAPH_SLEEP_SECOND(1)
        return CStatus();
    }
};

class MyNode2 : public CGraph::GNode {
public:
    CStatus run() override {
        printf("[%s], sleep for 2 second ...\n", this->getName().c_str());
        CGRAPH_SLEEP_SECOND(2)
        return CStatus();
    }
};

main.cpp

#include "MyNode.h"

using namespace CGraph;

int main() {
    /* 创建一个流水线，用于设定和执行流图信息 */
    GPipelinePtr pipeline = GPipelineFactory::create();
    GElementPtr a, b, c, d = nullptr;

    /* 注册节点之间的依赖关系 */
    pipeline->registerGElement<MyNode1>(&a, {}, "nodeA");
    pipeline->registerGElement<MyNode2>(&b, {a}, "nodeB");
    pipeline->registerGElement<MyNode1>(&c, {a}, "nodeC");
    pipeline->registerGElement<MyNode2>(&d, {b, c}, "nodeD");

    /* 执行流图框架 */
    pipeline->process();

    /* 清空流水线中所有的资源 */
    GPipelineFactory::remove(pipeline);

    return 0;
}

CGraph Demo <br> 如上图所示，图结构执行的时候，首先执行a节点。a节点执行完毕后，并行执行b和c节点。b和c节点全部执行完毕后，再执行d节点。
