AnnotationKeys

AnnotationKeys[obj]

列出可用于对象 obj 的所有注释键.

AnnotationKeys[{obj,itemspec}]

列出在 obj 中由 itemspec 指定的项可用的所有注释键.

更多信息

  • 通常用于提取与对象以及对象中的项关联的注释中的名称.
  • AnnotationKeys 给出对象及其项的 key->value 注释中所有名称 keys 的列表.
  • 带有注释的可能对象包括：
  • Audio带有时间和时长的音频
    BoundaryMeshRegion带单元的边界网格
    CSGRegion几何区域
    Graph带顶点和边的图
    MeshRegion带单元的网格区域
  • 每个对象 obj 的项规范 itemspec 在其参考页面中给出.
  • 与对象 obj 关联的选项名称是 obj 的标准注释，但 AnnotationRules 除外.

范例

打开所有单元 关闭所有单元

基本范例  (3)

获取图的标准注释列表：

Wolfram Language code: g = ExampleData[{"NetworkGraph", "FlorentineFamilies"}]
Wolfram Language code: AnnotationKeys[g]

对于顶点：

Wolfram Language code: AnnotationKeys[{g, "Medici"}]

对于边：

Wolfram Language code: AnnotationKeys[{g, "Medici""Ridolfi"}]

测试维度为1的单元中是否存在 MeshCellMarker 注释：

Wolfram Language code: mr = MengerMesh[2, MeshCellMarker -> {{1, 1} -> 1, {1, 2} -> 2, {1, 3} -> 3}]
Wolfram Language code: MemberQ[AnnotationKeys[{mr, 1}], MeshCellMarker]

获取索引为 {1,1} 的单元的标记：

Wolfram Language code: AnnotationValue[{mr, {1, 1}}, MeshCellMarker]

自动计算 Audio 对象的注释：

Wolfram Language code: a = AudioAnnotate[Import["ExampleData/rule30.wav"], "Loud"];
Wolfram Language code: AnnotationKeys[a]

提取更响亮时段的注释：

Wolfram Language code: AnnotationValue[a, "Loud"]

范围  (8)

图和网络  (6)

将 AnnotationKeys 应用于顶点：

Wolfram Language code: Graph[{Annotation[1, {VertexWeight -> 4, "Material" -> "Wood"}], 2, 3}, {12, 23, 31}]
Wolfram Language code: AnnotationKeys[{%, 1}]

应用于边：

Wolfram Language code: Graph[{1, 2, 3}, {Annotation[12, EdgeLabels -> "hello"], 23, 31}]
Wolfram Language code: AnnotationKeys[{%, 12}]

AnnotationKeys 适用于无向图：

Wolfram Language code: CycleGraph[5, VertexShapeFunction -> "Name"];
Wolfram Language code: AnnotationKeys[{[image], 12}]

有向图：

Wolfram Language code: CycleGraph[5, DirectedEdges -> True, EdgeStyle -> Arrowheads[Small], VertexShapeFunction -> "Name"];
Wolfram Language code: AnnotationKeys[{[image], 12}]

多重图：

Wolfram Language code: Module[{g}, g = Graph[Range[5], {12, 15, 23, 34, 45, 45, 45}, VertexCoordinates -> GraphEmbedding[CycleGraph[5]], VertexShapeFunction -> "Name", PerformanceGoal -> "Quality"]; MapThread[(AnnotationValue[{g, #1}, EdgeStyle] = #2)&, {EdgeList[g], {Gray, Blue, Red, Green, Brown, Brown, Brown}}]; g]
Wolfram Language code: AnnotationKeys[{%, 34}]

混合图：

Wolfram Language code: Module[{g}, g = Graph[Range[5], {12, 15, 23, 34, 45}, VertexCoordinates -> GraphEmbedding[CycleGraph[5]], VertexShapeFunction -> "Name", PerformanceGoal -> "Quality"]; MapThread[(AnnotationValue[{g, #1}, EdgeStyle] = #2)&, {EdgeList[g], {Gray, Blue, Red, Green, Brown}}]; g]
Wolfram Language code: AnnotationKeys[{%, 15}]

加权图：

Wolfram Language code: With[{g = CycleGraph[5], w = 0.3Range[5], pl = {Right, Above, Above, Right, Above} /. {Right -> {1 / 2, {-0.4, 1 / 2}}, Above -> {1 / 2, {1 / 2, 0}}}}, Graph[VertexList[g], EdgeList[g], EdgeWeight -> w, VertexShapeFunction -> "Name", EdgeLabels -> Thread[EdgeList[g] -> MapThread[Placed, {w, pl}]], VertexCoordinates -> GraphEmbedding[g]]];
Wolfram Language code: AnnotationKeys[{[image], 12}]

区域  (2)

AnnotationKeys 适用于 CSGRegion 对象：

Wolfram Language code: CSGRegion["Union", {Ball[], Cuboid[]}]
Wolfram Language code: AnnotationKeys[%]

及其子区域：

Wolfram Language code: CSGRegion["Union", {Ball[], Cuboid[]}]
Wolfram Language code: AnnotationKeys[{%, {1}}]

AnnotationKeys 返回标准的和用户定义的注释键：

Wolfram Language code: CSGRegion["Union", {Annotation[Ball[], "Material" -> "Wood"], Cuboid[]}]
Wolfram Language code: AnnotationKeys[{%, {1}}]

属性和关系  (6)

使用 Annotation 作为包装，在 Graph 之类的函数中指定注释：

Wolfram Language code: Graph[{Annotation[1, {VertexSize -> Medium, VertexStyle -> Red}], 2, 3}, {12, 23, 31}]

使用 AnnotationValue 提取值：

Wolfram Language code: g = CompleteGraph[4, VertexStyle -> {1 -> Red}, VertexSize -> Small]
Wolfram Language code: AnnotationValue[{g, 1}, VertexStyle]

对于未定义的注释，返回值 $Failed：

Wolfram Language code: AnnotationValue[{g, 1}, "foo"]
Wolfram Language code: MemberQ[AnnotationKeys[{g, 1}], "foo"]

使用 AnnotationValue 在图中设置注释：

Wolfram Language code: g = CompleteGraph[4]
Wolfram Language code: AnnotationValue[{g, 1}, VertexSize] = Small;

原始图已更改：

Wolfram Language code: g

使用 AnnotationValue 取消图中的注释：

Wolfram Language code: g = CompleteGraph[4, VertexSize -> {1 -> Small}]
Wolfram Language code: AnnotationValue[{g, 1}, VertexSize]=.;

原始图已更改：

Wolfram Language code: g

使用 Annotate 在新图中设置注释：

Wolfram Language code: g = CompleteGraph[4]
Wolfram Language code: Annotate[{g, 1}, VertexSize -> Small]

原始图不变：

Wolfram Language code: g

使用 AnnotationDelete 删除注释而不更改原始图：

Wolfram Language code: g = CompleteGraph[4, VertexSize -> {1 -> Small}]
Wolfram Language code: AnnotationDelete[{g, 1}, VertexSize]

原始图不变：

Wolfram Language code: g
