| inline

Definition at line 156 of file DiskUsageCounter.h.

## ◆ DiskUsageCounter() [2/2]

zypp::DiskUsageCounter::DiskUsageCounter | ( | MountPointSet | mps_r | ) |
| inline

Ctor taking the MountPointSet to compute.

Definition at line 160 of file DiskUsageCounter.h.

## Member Function Documentation

## ◆ setMountPoints()

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

Set a MountPointSet to compute.

Definition at line 165 of file DiskUsageCounter.h.

## ◆ getMountPoints()

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

Get the current MountPointSet.

Definition at line 169 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).

Definition at line 129 of file DiskUsageCounter.cc.

## ◆ justRootPartition()

DiskUsageCounter::MountPointSet zypp::DiskUsageCounter::justRootPartition | ( |  | ) |
| static

Only one entry for "/" to collect total sizes.

Definition at line 337 of file DiskUsageCounter.cc.

## ◆ disk_usage() [1/6]

DiskUsageCounter::MountPointSet zypp::DiskUsageCounter::disk_usage | ( | const ResPool & | pool | ) | const

Compute disk usage if the current transaction woud be commited.

Definition at line 92 of file DiskUsageCounter.cc.

## ◆ disk_usage() [2/6]

DiskUsageCounter::MountPointSet zypp::DiskUsageCounter::disk_usage | ( | sat::Solvable | solv_r | ) | const

Compute disk usage of a single Solvable.

Definition at line 108 of file DiskUsageCounter.cc.

## ◆ disk_usage() [3/6]

MountPointSet zypp::DiskUsageCounter::disk_usage | ( | const PoolItem & | pi_r | ) | const
| inline

## ◆ disk_usage() [5/6]

DiskUsageCounter::MountPointSet zypp::DiskUsageCounter::disk_usage | ( | const Bitmap & | bitmap_r | ) | const

Compute disk usage of a collection defined by a solvable bitmap.

Definition at line 120 of file DiskUsageCounter.cc.

## ◆ disk_usage() [6/6]

template<class Iterator>

|  | Iterator | end_r ) const
| inline
