Detailed Description

Track changing files or directories.

Compute timestamp and checksum for individual files or directories (recursively) to track changing content.

The timestamp most probably denotes the time the data were changed the last time, that's why it is exposed.

The checksum however is an implementation detail and of no use outside this class. operator== tells if the checksums of two rRepoStatus are the same.

Constructor & Destructor Documentation

◆ RepoStatus() [1/2]

zypp::RepoStatus::RepoStatus ( )

Default ctor.

Definition at line 74 of file RepoStatus.cc.

◆ RepoStatus() [2/2]

zypp::RepoStatus::RepoStatus ( const Pathname &  path_r)
explicit

Compute status for single file or directory (recursively)

Note
Construction from a non existing file will result in an empty status.

◆ fromCookieFile()

RepoStatus zypp::RepoStatus::fromCookieFile ( const Pathname &  path)
static

Reads the status from a cookie file.

Returns
An empty RepoStatus if the file does not exist or is not readable.

◆ saveToCookieFile()

void zypp::RepoStatus::saveToCookieFile ( const Pathname &  path_r) const
