modelbox::FlowUnitDesc

描述功能单元描述信息的数据结构

SetFlowUnitGroupType

     void SetFlowUnitGroupType(const std::string &group_type)

• group_type (string) —— 功能单元的组类型，限制为智能a-z, A-Z, 0-9, _，只允许存在一个/, 已有的group_type为“Image"等等

return:

无，非必须， 默认为"generic"

AddFlowUnitInput

     Status AddFlowUnitInput(const FlowUnitInput &flowunit_input);

args:

• flowunit_input (modelbox::FlowUnitInput) —— flowunit input对象， 参考flowunit_input

return:

modelbox::Status, 添加flowunit input返回的status状态

AddFlowUnitOutput

     Status AddFlowUnitOutput(const FlowUnitOutput &flowunit_output);

args:

• flowunit_output (modelbox::FlowUnitOutput) —— flowunit output对象， 参考flowunit_output

return:

modelbox::Status, 添加flowunit output返回的status状态

AddFlowUnitOption

     Status AddFlowUnitOption(const FlowUnitOption &flowunit_option);

args:

• flowunit_option (modelbox::FlowUnitOption) —— flowunit option对象， 参考flowunit_option

return:

modelbox::Status, 添加flowunit option返回的status状态

SetFlowType

     void SetFlowType(FlowType flow_type);

args:

• flow_type (FlowType) —— 数据处理的 type， 分为NORMAL和STREAM

return:

无, 默认为NORMAL

SetOutputType

     void SetOutputType(FlowOutputType output_type)

args:

• output_type (FlowOutputType) —— 数据输出type， 分为ORIGIN, EXPAND, COLLAPSE

return:

无

SetConditionType

     void SetConditionType(ConditionType condition_type)

args:

• condition_type (ConditionType) —— 功能单元条件type， 分为IF_ELSE, NONE

return:

无

note:

1. 上述3个接口共同确认功能单元为五种类型，分别为NORMAL, STREAM, IF_ELSE, EXPAND, COLLAPSE
2. 只需要设置某个特定接口即可
3. 五种flowunit设置样例如下：

    MODELBOX_FLOWUNIT(HTTPServerAsync, desc) {
        ...
        // 1. NORMAL
        desc.SetFlowType(modelbox::NORMAL);

        // 2. STREAM
        desc.SetFlowType(modelbox::STREAM);

        // 3. IF_ELSE
        desc.SetConditionType(modelbox::IF_ELSE);

        // 4. EXPAND
        desc.SetOutputType(modelbox::EXPAND);

        // 5. COLLAPSE
        desc.SetOutputType(modelbox::COLLAPSE);
        ...
    }

SetInputContiguous

     void SetInputContiguous(bool is_input_contiguous)

args:

• is_input_contiguous (bool) —— 输入内存是否连续

return:

无, 默认为true

SetExceptionVisible

     void SetExceptionVisible(bool is_exception_visible)

args:

• is_exception_visible (bool) —— 异常是否可见

return:

无, 默认为false

example:

    MODELBOX_FLOWUNIT(HTTPServerAsync, desc) {
        desc.SetFlowUnitName(FLOWUNIT_NAME);
        desc.AddFlowUnitOutput({"out_request_info"});
        desc.SetFlowType(modelbox::NORMAL);
        desc.SetFlowUnitGroupType("Input");
        desc.SetDescription(FLOWUNIT_DESC);
        desc.SetInputContiguous(false);
        desc.SetExceptionVisible(true);
        desc.AddFlowUnitOption(modelbox::FlowUnitOption("endpoint", "string", true,
                                                        "https://127.0.0.1:8080",
                                                        "http server listen URL."));
        desc.AddFlowUnitOption(modelbox::FlowUnitOption(
            "max_requests", "integer", true, "1000", "max http request."));
        desc.AddFlowUnitOption(
            modelbox::FlowUnitOption("keepalive_timeout_sec", "integer", false, "200",
                                    "keep-alive timeout time(sec)"));
        desc.AddFlowUnitOption(
            modelbox::FlowUnitOption("cert", "string", false, "", "cert file path"));
        desc.AddFlowUnitOption(
            modelbox::FlowUnitOption("key", "string", false, "", "key file path"));
        desc.AddFlowUnitOption(modelbox::FlowUnitOption(
            "passwd", "string", false, "", "encrypted key file password."));
        desc.AddFlowUnitOption(modelbox::FlowUnitOption(
            "key_pass", "string", false, "", "key for encrypted password."));

    }
