OverriddenLogic 覆写逻辑

1. 结构声明​

class OverriddenLogic extends BaseNode {
    overriddenModule: string;
    name: string = '';
    description: string;
    triggerType?: string;
    cron?: string;
    transactional?: Transactional;
    typeParams?: Array<TypeParam>;
    params: Array<Param>;
    returns: Array<Return>;
    variables: Array<Variable>;
    body: Array<LogicItem>;
    playground: Array<LogicItem>;
}

2. 节点示例​

    ],
    "playground": []
}

对应的代码如下：​

@override(lcap_permission)
logic checkPermission(userId: String, resourceValue: String, resourceType: String, clientType: String) => result: Boolean {
    if (resourceValue == '/index') {
        result = true
    } else {
    }
    end
}
