## Detailed Description
该QAbstractFileEngine类提供了访问文件系统的抽象。
该[QDir](qdir.html),[QFile](qfile.html)和[QFileInfo](qfileinfo.html)类中的所有使用内部一个QAbstractFileEngine的。如果您创建自己的QAbstractFileEngine子类(和使用Qt创建一个注册它[QAbstractFileEngineHandler](qabstractfileenginehandler.html)子类) ,当路径是指你的文件引擎处理您的文件引擎将被使用。
一个QAbstractFileEngine是指一个文件或一个目录。如果所指的是一个文件时,[setFileName](qabstractfileengine.html#setFileName)( )[rename](qabstractfileengine.html#rename)()和[remove](qabstractfileengine.html#remove)()函数是适用的。如果所指的是一个目录[mkdir](qabstractfileengine.html#mkdir)( )[rmdir](qabstractfileengine.html#rmdir)()和[entryList](qabstractfileengine.html#entryList)()函数是适用的。在所有情况下[caseSensitive](qabstractfileengine.html#caseSensitive)( )[isRelativePath](qabstractfileengine.html#isRelativePath)( )[fileFlags](qabstractfileengine.html#fileFlags)( )[ownerId](qabstractfileengine.html#ownerId)( )[owner](qabstractfileengine.html#owner)()和[fileTime](qabstractfileengine.html#fileTime)()函数是适用的。
一个QAbstractFileEngine子类可以被创建来做到同步网络I / O的文件系统操作,本地文件系统操作,或作为一个系统资源的访问基于文件的资源。
