-对于第3条，必须首先手动解除其本身的引用，然后将转变为第2条。 - -# 图元删除 -**显然**，无论是什么种类的图元，删除一个图元会影响到的元素只有引用它的图层，所以我们将SimpleElement与GroupElement合并成一种情况讨论。 - -当删除一个图元时，该图元一定满足且只满足以下条件中的一条： -1. 是一个GraphicElement，未被其他图层引用； -2. 是一个GraphicElement，被其他图层引用。 - -对于第1条，删除绝对安全。 - -对于第2条，将引用关系手动解除后，删除安全。 - -# 图层移动 -## 条件分析 -图层移动时，显然，被移动的节点只影响它本身及它的子图层， -移动的目标节点只影响它本身及它的父图层，那么： - -(1) 被移动的图层一定满足且只满足以下条件中的一条： -1. 是一个Folder节点，无对应的GroupElement引用，子节点无引用GroupElement； -2. 是一个Folder节点，无对应的GroupElement引用，子节点存在引用GroupElement； -3. 是一个Folder节点，存在对应的GroupElement引用； -4. 是一个Leaf节点，引用了GroupElement； -5. 是一个Leaf节点，未引用GroupElement。 - -(2) 目标FolderLayer一定满足且只满足以下条件中的一条： -1. 自身无对应的GroupElement引用，无父节点有GroupElement引用； -2. 自身无对应的GroupElement引用，存在父节点有GroupElement引用； -3. 自身存在对应的GroupElement引用。 - -显然，以上条件的全组合可以覆盖所有情况。 -由于： -- `(1) 1` 与 `(2) 中的任一条件`进行组合显然是绝对安全的； -- `(1) 3` 中自身提供的GroupElement并不会影响移动； -- `(1) 5` 与 `(2) 中的任一条件`进行组合显然是绝对安全的； -- `(1) 中的任一条件` 与 `(2) 1` 进行组合显然是绝对安全的。 - -所以接下来对于除去以上情况的所有组合情况进行讨论。 -## 讨论证明 -### `(1) 2` - `(2) 2` -当且仅当被移动的图层的子节点引用的GroupElement 与 目标图层父节点提供的GroupElement 相同时，移动不安全。 -### `(1) 4` - `(2) 2` -当且仅当被移动的图层引用的GroupElement 与 目标图层父节点提供的 GroupElement 相同时，移动不安全。 -### `(2) 3` 的特殊讨论 -当且仅当自身提供的GroupElement 被 被移动图层或其子节点引用时，需要处理其自身情况，否则无视其自身提供的GroupElement，与 `(2) 1` 或 `(2) 2` 视为同情况处理。 - -## 结论 -当且仅当被移动的图层或其子节点所引用的GroupElement 与 目标图层或其父节点所提供的GroupElement 相同时，移动不安全；其余情况均安全。 \ No newline at end of file
