CallFunction 调用函数

1. 结构声明

TS Declaration

class CallFunction extends LogicItem {
    calleeNamespace: string;
    calleeName: string;
    shortcut?: boolean;
    typeArguments?: Array<TypeAnnotation>;
    arguments: Array<Argument>;
}

JSON Schema

{
    "type": "object",
    "properties": {
        "composedBy": {
            "type": "array",
            "items": {
                "type": "string"
            }
        },
        "label": {
            "type": "string"
        },
        "description": {
            "type": "string"
        },
        "folded": {
            "type": "boolean"
        },
        "offsetX": {
            "type": "number"
        },
        "offsetY": {
            "type": "number"
        },
        "typeAnnotation": {
            "$ref": "#/definitions/TypeAnnotation"
        },
        "calleeNamespace": {
            "type": "string"
        },
        "calleeName": {
            "type": "string"
        },
        "shortcut": {
            "type": "boolean"
        },
        "typeArguments": {
            "type": "array",
            "items": {
                "$ref": "#/definitions/TypeAnnotation"
            }
        },
        "arguments": {
            "type": "array",
            "items": {
                "$ref": "#/definitions/Argument"
            }
        }
    },
    "required": [
        "calleeNamespace",
        "calleeName",
        "arguments"
    ],
    "additionalProperties": false
}

2. 节点示例

(1) 示例

AST 如下：

JSON

{
    "concept": "CallFunction",
    "label": "调用逻辑",
    "calleeNamespace": "nasl.util",
    "calleeName": "Clone",
    "arguments": [
        {
            "concept": "Argument",
            "keyword": "obj",
            "expression": {
                "concept": "Identifier",
                "namespace": "",
                "name": "student"
            }
        }
    ]
}

YAML

concept: CallFunction
label: 调用逻辑
calleeNamespace: nasl.util
calleeName: Clone
arguments:
  - concept: Argument
    keyword: obj
    expression:
      concept: Identifier
      namespace: ""
      name: student

对应的代码如下：

文本化 NASL

nasl::util::Clone(student)

Natural TS

nasl.util.Clone(student)

(2) 带 lambda 的入参

AST 如下：

JSON

    "concept": "CallFunction",
    "label": "内置函数",
    "calleeNamespace": "nasl.util",
    "calleeName": "ListFilter",
    "typeArguments": [],
    "arguments": [
        {
            "concept": "Argument",
            "keyword": "list",
            "expression": {
                "concept": "Identifier",
                "namespace": "",
                "name": "list"
            }
        },
        {
            "concept": "Argument",
            "keyword": "by",
            "expression": {

                        "description": ""
                    }
                ],

                            "property": {
                                "concept": "Identifier",
                                "namespace": "",
                                "name": "productReport"
                            }
                        },
                        "property": {
                            "concept": "Identifier",
                            "namespace": "",
                            "name": "executed"
                        }
                    },
                    "right": {
                        "concept": "NullLiteral"
                    },
                    "operator": "!="
                }
            }
        }
    ]
}

YAML

concept: CallFunction
label: 内置函数
calleeNamespace: nasl.util
calleeName: ListFilter
typeArguments: []
arguments:
  - concept: Argument
    keyword: list
    expression:
      concept: Identifier
      namespace: ""
      name: list
  - concept: Argument
    keyword: by
    expression:
      concept: AnonymousFunction
      params:
        - concept: Param
          name: item
          description: ""
      body:
        concept: BinaryExpression
        left:
          concept: MemberExpression
          object:
            concept: MemberExpression
            object:
              concept: Identifier
              namespace: ""
              name: item
            property:
              concept: Identifier

          property:
            concept: Identifier

            name: executed
        right:
          concept: NullLiteral
        operator: "!="

对应的代码如下：

文本化 NASL

nasl::util::ListFilter(list, { item: String => item.productReport.executed != null })

Natural TS

nasl.util.ListFilter(list, (item: String) => item.productReport.executed != null)
