acdk::io::FileSystem Class Reference

Inheritance diagram for acdk::io::FileSystem:

Detailed Description

It cooperates with FileImpl. An important reason to introduce this indirection in the File interface is to be able to support archive files (TAR, ZIP) remote file systems (FTP) and other virtual file systems like DCOM documents or shell directories.

Please refer also to  acdk::io::FileSystem.

Member Function Documentation

virtual RFile acdk::io::FileSystem::file (  IN(RString)  path  )  [pure virtual]

creates an instance of given file. Parameters: path  is without the FS name Returns: returns a new File. Implemented in acdk::io::RessourceFileSystem, acdk::io::StandardFileSystem, acdk::net::ftp::FTPFileSystem, acdk::net::srfsys::SRFileSystemClient, acdk::net::UrlFileSystem, acdk::vfile::tar::TarFileSystem, and acdk::vfile::zip::ZipFileSystem.

RFileSystem acdk::io::FileSystem::findFileSystem (  IN(RString)  file  )  [static]

virtual RFileImpl acdk::io::FileSystem::getFileImpl (  IN(RString)  fqpath  )  [pure virtual]

returns a file implementation for this full qualified file implementation Implemented in acdk::io::RessourceFileSystem, acdk::io::StandardFileSystem, acdk::net::ftp::FTPFileSystem, acdk::net::srfsys::SRFileSystemClient, acdk::net::UrlFileSystem, acdk::vfile::tar::TarFileSystem, and acdk::vfile::zip::ZipFileSystem.

virtual RString acdk::io::FileSystem::getRootName (   )  [pure virtual]

returns the root name of the this file system Examples: /home/roger/myfile.zip ftp://ftp.artefaktur.com Implemented in acdk::io::RessourceFileSystem, acdk::io::StandardFileSystem, acdk::net::ftp::FTPFileSystem, acdk::net::srfsys::SRFileSystemClient, acdk::net::UrlFileSystem, acdk::vfile::tar::TarFileSystem, and acdk::vfile::zip::ZipFileSystem.

virtual RFileArray acdk::io::FileSystem::listFiles (  IN(RString)  directory, int  listflags )  [pure virtual]

Parameters: directory  the absolute name with out the FSname listflags  a combination of ListFlags Returns: list of files Implemented in acdk::io::RessourceFileSystem, acdk::io::StandardFileSystem, acdk::net::ftp::FTPFileSystem, acdk::net::srfsys::SRFileSystemClient, acdk::net::UrlFileSystem, acdk::vfile::tar::TarFileSystem, and acdk::vfile::zip::ZipFileSystem.

void acdk::io::FileSystem::loadPropertyFileSystemHandler (   )  [static, protected]

look if in the Systems properterty a Filesystem is registered for this filename

virtual bool acdk::io::FileSystem::ownsFile (  IN(RString)  fname  )  [pure virtual]

Returns: true, if given (absolut) file name is part of this file system. Example: /dir/subdir/file.dat -> owns StandardFileSystem /dir/file.zip@/subdir/file.data -> owns ZipFileSystem(/dir/file.zip) Implemented in acdk::io::RessourceFileSystem, acdk::io::StandardFileSystem, acdk::net::ftp::FTPFileSystem, acdk::net::srfsys::SRFileSystemClient, acdk::net::UrlFileSystem, acdk::vfile::tar::TarFileSystem, and acdk::vfile::zip::ZipFileSystem.

void acdk::io::FileSystem::registerFileSystem (  IN(RFileSystem)  fs  )  [static]

To improve performance of File system File system will be cached in a weak referenced hash map. This means, the FileSystem will only hold, if there is an File instance in this FileSystem.

void acdk::io::FileSystem::registerFileSystemFactory (  IN(RFileSystemFactory)  fsf  )  [static]

void acdk::io::FileSystem::unRegisterFileSystemFactory (  IN(RFileSystemFactory)  fsf  )  [static]
