Function MapDirectSlice

mapper_func.go:134–153

MapDirectSlice 批量映射 使用示例: dtos := mapper.MapDirectSlice[User, UserDTO](users)

(from []From)

// MapDirectSlice 批量映射
// 使用示例: dtos := mapper.MapDirectSlice[User, UserDTO](users)
func MapDirectSlice[From, To any](from []From) []To {
	if from == nil {
		return nil
	}
	
	// 尝试预获取映射关系以优化批量操作
	fromType := reflect.TypeOf((*From)(nil)).Elem()
	toType := reflect.TypeOf((*To)(nil)).Elem()
	
	_, hasCache := getFieldMappings(fromType, toType)
	if !hasCache {
		buildFieldMappings(fromType, toType)
	}
	
	result := make([]To, len(from))
	for i, v := range from {
		result[i] = MapDirect[From, To](v)
	}
	return result
}

// MapDirectPtrSlice 指针切片映射
// 使用示例: dtos := mapper.MapDirectPtrSlice[User, UserDTO](&users)
