Member Function Documentation

setMountPoints()

void zypp::DiskUsageCounter::setMountPoints ( const MountPointSet &  mps_r )

inline

Set a MountPointSet to compute.

Definition at line 164 of file DiskUsageCounter.h.

getMountPoints()

const MountPointSet & zypp::DiskUsageCounter::getMountPoints ( ) const

inline

Get the current MountPointSet.

Definition at line 168 of file DiskUsageCounter.h.

detectMountPoints()

DiskUsageCounter::MountPointSet zypp::DiskUsageCounter::detectMountPoints ( const std::string &  rootdir = "/" )

static

Get mountpoints of system below rootdir If we happen to detect snapshotting btrfs partitions, the MountPoint::growonly hint is set.

Disk usage computation will assume that deleted packages will not free any space (kept in a snapshot).
