Class UpdateManager

java.lang.Object

org.nuxeo.connect.update.task.update.UpdateManager

public class UpdateManager
extends Object

Manage jar versions update.

To manipulate the jar version registry you need to create a new instance of this class.

If you want to modify the registry then you may want to synchronize the entire update process. This is how is done in the Task run method.

Only reading the registry is thread safe.

TODO backup md5 are not really used since we rely on versions - we can remove md5

getRollbackTarget

public File getRollbackTarget(RollbackOptions opt)

Ugly method to know what file is going to be deleted before it is, so that it can be undeployed for hotreload.

FIXME: will only handle simple cases for now (ignores version, etc...), e.g only tested with the main Studio jars. Should use version from RollbackOptions

Since:

5.6
