# IResourceLoader::CanLoad
```cpp
virtual bool CanLoad(const Containers::String& path) const = 0
```
纯虚方法,检查此加载器是否能加载指定路径的资源。通过比对路径扩展名与支持列表判断。
**参数:**
- `path` - 资源路径
**返回:** 如果扩展名在支持列表中则返回 true
**复杂度:** O(k)k 为扩展名数量
**示例:**
```cpp
bool TextureLoader::CanLoad(const Containers::String& path) const {
Containers::String ext = GetExtension(path);
auto supported = GetSupportedExtensions();
for (const auto& s : supported) {
if (ext == s) return true;
}
return false;
}
```
