- `key` - 要删除的键
|
||
|
||
**返回：** 如果元素被删除返回 `true`，如果键不存在返回 `false`。
|
||
|
||
**复杂度：** O(1) 平均，最坏 O(n)
|
||
|
||
**示例：**
|
||
|
||
```cpp
|
||
XCEngine::Containers::HashMap<int, const char*> map;
|
||
map.Insert(1, "one");
|
||
map.Insert(2, "two");
|
||
map.Insert(3, "three");
|
||
|
||
bool erased = map.Erase(2); // 返回 true
|
||
|
||
if (!map.Contains(2)) {
|
||
std::cout << "Key 2 removed" << std::endl; // 输出 "Key 2 removed"
