# Array::EmplaceBack()
|
||||
|
||||
```cpp
|
||||
template<typename... Args>
|
||||
T& EmplaceBack(Args&&... args);
|
||||
```
|
||||
|
||||
在数组末尾就地构造一个元素,直接在内存中构造,不产生临时对象。
|
||||
|
||||
**优势:**
|
||||
- 避免拷贝或移动开销
|
||||
- 直接在底层缓冲区末尾构造元素
|
||||
- 参数完美转发,支持任意构造参数
|
||||
|
||||
**参数:**
|
||||
- `args` - 转发给 `T` 构造函数的参数包
|
||||
|
||||
**返回:** 新构造元素的引用
|
||||
|
||||
**复杂度:** 均摊 O(1)
|
||||
|
||||
**线程安全:** ❌ 操作期间不可并发访问
|
||||
|
||||
**示例:**
|
||||
|
||||
```cpp
|
||||
struct Vertex {
|
||||
float x, y, z;
|
||||
Vertex(float x_, float y_, float z_) : x(x_), y(y_), z(z_) {}
|
||||
};
|
||||
|
||||
Containers::Array<Vertex> vertices;
|
||||
|
||||
// EmplaceBack 直接构造,不产生临时 Vertex 对象
|
||||
vertices.EmplaceBack(1.0f, 2.0f, 3.0f);
|
||||
vertices.EmplaceBack(4.0f, 5.0f, 6.0f);
|
||||
|
||||
// 对比 PushBack(需要先构造临时对象)
|
||||
Vertex v(7.0f, 8.0f, 9.0f);
|
||||
vertices.PushBack(v); // 产生拷贝或移动
|
||||
|
||||
// EmplaceBack 更高效,始终优先使用
|
||||
```
