Member Function Documentation

void zypp::media::MediaISO::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 144 of file MediaISO.cc.

void zypp::media::MediaISO::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 249 of file MediaISO.cc.

References zypp::media::MediaHandler::_parentId, zypp::ui::asString(), zypp::media::MediaHandler::attachPoint(), zypp::media::MediaManager::release(), and zypp::media::Mount::umount().

void zypp::media::MediaISO::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 265 of file MediaISO.cc.

References zypp::media::MediaHandler::getFile().

void zypp::media::MediaISO::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 271 of file MediaISO.cc.

References zypp::media::MediaHandler::getDir().

void zypp::media::MediaISO::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 278 of file MediaISO.cc.

References zypp::media::MediaHandler::getDirInfo().

void zypp::media::MediaISO::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 286 of file MediaISO.cc.

References zypp::media::MediaHandler::getDirInfo().

bool zypp::media::MediaISO::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.
