## Member Function Documentation

## ◆ file()

const Pathname & zypp::target::SolvIdentFile::file | ( |  | ) | const
| inline

Return the file path.

Definition at line 47 of file SolvIdentFile.h.

## ◆ data()

const Data & zypp::target::SolvIdentFile::data | ( |  | ) | const
| inline

Return the data.

The file is read once on demand. Returns empty Data if the file does not exist or is not readable.

## ◆ setData()

void zypp::target::SolvIdentFile::setData | ( | const Data & | data_r | ) |
| inline

Store new Data.

Write the new Data to file, unless we know it did not change. The directory containing file must exist.

Definition at line 70 of file SolvIdentFile.h.

## ◆ differs()

bool zypp::target::SolvIdentFile::differs | ( | const Data & | lhs,
|  | const Data & | rhs ) const
| inlineprivate

Helper testing whether two Data differ.
