Example 1 with Semver

use of org.expath.pkg.repo.deps.Semver in project exist by eXist-db.

the class AppRestoreUtils method checkApps.

/**
 * Inspects the apps contained in the backup against installed apps in the database
 * and return a set of symbolic backup paths pointing to the collection of those
 * apps for which newer versions are installed within the database. The returned
 * paths may then be ignored during a restore.
 *
 * The method attempts to be fail safe to make sure even bad backups can be restored. Errors
 * reading package descriptors are thus only logged and should not abort the process.
 *
 * @param broker the broker used for reading the backup and retrieving the expath repo
 * @param descriptors a queue of backup descriptors to inspect
 * @return a set of paths for which newer versions exist in the database. may be empty.
