|
|
|
|||
|
|
**命名空间**: `XCEngine::Resources`
|
|||
|
|
|
|||
|
|
**类型**: `class` (abstract)
|
|||
|
|
|
|||
|
|
**描述**: 资源基类接口，所有具体资源类型（Texture、Mesh、Material 等）都必须继承自此类。
|

|
|
|||
|
|
## 概述
|
|||
|
|
|
|||
|
|
`IResource` 是 XCEngine 资源管理系统的核心抽象基类。它定义了所有资源共有的基本属性和行为，包括资源类型、名称、路径、GUID、内存大小和有效性状态。
|
|||

## 公共方法
|
|||
|
|
|
|||
|
|
| 方法 | 描述 |
|
|||
|
|
|------|------|
|
|||
|
|
| `ResourceType GetType() const` | 获取资源类型 |
|
|||
|
|
| `const Containers::String& GetName() const` | 获取资源名称 |
|
|||
|
|
| `const Containers::String& GetPath() const` | 获取资源路径 |
|
|||
|
|
| `ResourceGUID GetGUID() const` | 获取全局唯一标识符 |
|
|||
|
|
| `bool IsValid() const` | 检查资源是否有效 |
|
|||
|
|
| `size_t GetMemorySize() const` | 获取资源占用的内存大小（字节） |
|
|||
|
|
| `void Release()` | 释放资源引用 |
|
|||
|
|
| `void Initialize(const ConstructParams& params)` | 使用构造参数初始化资源 |
|
|||
|
|

|
|||
|
|
|
|||
|
|
### 构造参数

|
|||
|
|
| 成员 | 类型 | 描述 |
|
|||
|
|
|------|------|------|
|
|||
|
|
| `m_name` | `Containers::String` | 资源名称 |
|
|||
|
|
| `m_path` | `Containers::String` | 资源路径 |
|
|||
|
|
| `m_guid` | `ResourceGUID` | 全局唯一标识符 |
|
|||
|
|
| `m_isValid` | `bool` | 资源是否有效 |
|
|||
|
|
| `m_memorySize` | `size_t` | 内存占用大小 |
|
|||
|
|
|
|||
|
|
## 使用示例
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
class MyResource : public IResource {
|
|||
|
|
public:
|
|||
|
|
ResourceType GetType() const override { return ResourceType::Custom; }
|
|||
|
|
const Containers::String& GetName() const override { return m_name; }
|
|||
|
|
const Containers::String& GetPath() const override { return m_path; }
|
|||
|
|
ResourceGUID GetGUID() const override { return m_guid; }
|
|||
|
|
bool IsValid() const override { return m_isValid; }
|
|||
|
|
size_t GetMemorySize() const override { return m_memorySize; }
|
|||
|
|
void Release() override { /* 释放逻辑 */ }
|
|||
|
|
};
|
|||
|
|
```
