# RHISampler::GetID
|
||
|
||
```cpp
|
||
virtual unsigned int GetID() = 0;
|
||
```
|
||
|
||
获取采样器的唯一标识符。该方法返回分配给采样器的唯一整数 ID，可用于采样器的识别、缓存管理或调试目的。
|
||
|
||
**参数：** 无
|
||
|
||
**返回：** 采样器的唯一无符号整数标识符
|
||
|
||
**线程安全：** ❌
|
||
|
||
**复杂度：** O(1)
|
||
|
||
**示例：**
|
||
|
||
```cpp
|
||
#include "XCEngine/RHI/RHISampler.h"
|
||
|
||
class MySampler : public XCEngine::RHI::RHISampler {
|
||
public:
|
||
void Shutdown() override { }
|
||
void Bind(unsigned int unit) override { }
|
||
void Unbind(unsigned int unit) override { }
|
||
void* GetNativeHandle() override { return nullptr; }
|
||
unsigned int GetID() override { return m_id; }
|
||
|
||
private:
|
||
unsigned int m_id = 1;
|
||
};
|
||
|
||
void Example() {
|
||
MySampler sampler1;
|
||
MySampler sampler2;
|
||
unsigned int id1 = sampler1.GetID();
|
||
unsigned int id2 = sampler2.GetID();
|
||
}
|
||
```
