Call concrete handler to attach the media.
Asserted that not already attached, and attachPoint is a directory.
| next | try next available device in turn until end of device list is reached (for media which are accessible through multiple devices like cdroms). |

| void zypp::media::MediaNFS::releaseFrom | ( | const std::string & | ejectDev | ) | [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.
| ejectDev | Device to eject. None if empty. |

| void zypp::media::MediaNFS::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'.

| void zypp::media::MediaNFS::getDir | ( | const Pathname & | dirname, | |

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.

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.

| void zypp::media::MediaNFS::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.
