Struct ResourceManage 

Source
pub struct ResourceManage { /* private fields */ }
Expand description

资源管理器,维护文档中所有资源的 ID 索引。

对应 Java: org.ofdrw.reader.ResourceManage

提供按 ID 随机访问资源的能力。资源来源于 DocumentRes.xml 和 PublicRes.xml 中声明的资源序列。

Implementations§

Source§

impl ResourceManage

Source

pub fn new() -> Self

创建空的资源管理器。

Source

pub fn from_items(items: Vec<ResourceItem>) -> Self

从资源条目列表构建资源管理器。

Source

pub fn insert(&mut self, item: ResourceItem)

插入一个资源条目。如果 ID 已存在则覆盖。

Source

pub fn get(&self, id: &str) -> Option<&ResourceItem>

按 ID 获取资源条目。

对应 Java: ResourceManage.get(String id)

Source

pub fn all(&self) -> &HashMap<String, ResourceItem>

获取所有资源条目。

Source

pub fn ids_by_type(&self, resource_type: ResourceType) -> &[String]

按类型获取资源 ID 列表。

Source

pub fn items_by_type(&self, resource_type: ResourceType) -> Vec<&ResourceItem>

获取指定类型的全部资源条目。

Source

pub fn len(&self) -> usize

资源总数。

Source

pub fn is_empty(&self) -> bool

资源管理器是否为空。
