Member Function Documentation

void zypp::media::MediaDIR::attachTo (  bool  next = false  )  [protected, virtual]

Call concrete handler to attach the media. Asserted that not already attached, and attachPoint is a directory. Parameters: next  try next available device in turn until end of device list is reached (for media which are accessible through multiple devices like cdroms). Exceptions: MediaException  Implements zypp::media::MediaHandler. Definition at line 65 of file MediaDIR.cc. References zypp::media::MediaHandler::attachPoint(), zypp::media::MediaHandler::getRealPath(), zypp::filesystem::PathInfo::isDir(), zypp::media::MediaHandler::setAttachPoint(), zypp::media::MediaHandler::url(), and ZYPP_THROW.

void zypp::media::MediaDIR::releaseFrom (  bool  eject  )  [protected, virtual]

Call concrete handler to release the media. If eject is true, and the media is used in one handler instance only, physically eject the media (i.e. CD-ROM). Asserted that media is attached. Exceptions: MediaException  Implements zypp::media::MediaHandler. Definition at line 120 of file MediaDIR.cc.

void zypp::media::MediaDIR::getFile (  const Pathname &  filename  )  const [protected, virtual]

Call concrete handler to provide file below attach point. Default implementation provided, that returns whether a file is located at 'localRoot + filename'. Asserted that media is attached. Exceptions: MediaException  Implements zypp::media::MediaHandler. Definition at line 133 of file MediaDIR.cc. References zypp::media::MediaHandler::getFile().

void zypp::media::MediaDIR::getDir (  const Pathname &  dirname, bool  recurse_r )  const [protected, virtual]

Call concrete handler to provide directory content (not recursive!) below attach point. Return E_not_supported_by_media if media does not support retrieval of directory content. Default implementation provided, that returns whether a directory is located at 'localRoot + dirname'. Asserted that media is attached. Exceptions: MediaException  Implements zypp::media::MediaHandler. Definition at line 145 of file MediaDIR.cc. References zypp::media::MediaHandler::getDir().

void zypp::media::MediaDIR::getDirInfo (  std::list< std::string > &  retlist, const Pathname &  dirname, bool  dots = true )  const [protected, virtual]

Call concrete handler to provide a content list of directory on media via retlist. If dots is false entries starting with '.' are not reported. Return E_not_supported_by_media if media does not support retrieval of directory content. Default implementation provided, that returns the content of a directory at 'localRoot + dirnname' retrieved via 'readdir'. Asserted that media is attached and retlist is empty. Exceptions: MediaException  Implements zypp::media::MediaHandler. Definition at line 158 of file MediaDIR.cc. References zypp::media::MediaHandler::getDirInfo().

void zypp::media::MediaDIR::getDirInfo (  filesystem::DirContent &  retlist, const Pathname &  dirname, bool  dots = true )  const [protected, virtual]

Basically the same as getDirInfo above. The content list is returned as filesystem::DirContent, which includes name and filetype of each directory entry. Retrieving the filetype usg. requires an additional stat call for each entry, thus it's more expensive than a simple readdir. Asserted that media is attached and retlist is empty. Exceptions: MediaException  Implements zypp::media::MediaHandler. Definition at line 172 of file MediaDIR.cc. References zypp::media::MediaHandler::getDirInfo().

bool zypp::media::MediaDIR::getDoesFileExist (  const Pathname &  filename  )  const [protected, virtual]

check if a file exists Asserted that url is a file and not a dir. Exceptions: MediaException  Implements zypp::media::MediaHandler. Definition at line 178 of file MediaDIR.cc. References zypp::media::MediaHandler::getDoesFileExist().
