ResourceLocator

Struct ResourceLocator 

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

资源定位器,维护 OFD 容器内的当前工作目录路径。

对应 Java: org.ofdrw.reader.ResourceLocator

提供 cd(切换目录)、pwd(打印当前目录)、save/restore (保存/恢复目录栈)等操作,用于在 OFD ZIP 归档内构建绝对路径。

Implementations§

Source§

impl ResourceLocator

Source

pub fn new() -> Self

创建新的资源定位器,默认位于根目录 “/”。

Source

pub fn save(&mut self)

保存当前工作路径到栈中。

对应 Java: ResourceLocator.save()

Source

pub fn restore(&mut self)

还原上一次保存的工作路径。

如果没有保存过路径,则不做任何操作。

对应 Java: ResourceLocator.restore()

Source

pub fn cd(&mut self, path: &str) -> Result<(), ErrorPathException>

切换到指定路径。

对应 Java: ResourceLocator.cd(String)

§错误

路径无效时返回 ErrorPathException

Source

pub fn reset(&mut self)

重置工作路径到根目录。

对应 Java: ResourceLocator.restWd()

Source

pub fn pwd(&self) -> String

打印当前工作目录路径。

对应 Java: ResourceLocator.pwd()

Source

pub fn to_absolute_path(&self, path: &str) -> String

将路径转换为绝对路径。

对应 Java: ResourceLocator.toAbsolutePath(String)

Source

pub fn get_abs_to(&self, path: &str) -> String

获取以当前路径为基础的容器内绝对路径。

对应 Java: ResourceLocator.getAbsTo(ST_Loc)
