public abstract class AbstractRepositoryTask
extends AbstractTask

An abstract implementation of AbstractTask which simply wraps the execute call in a try/catch block, avoiding many verbose and irrelevant code lines in actual tasks, leaving room for smarter and more interesting exception handling, when they can actually be handled.

Description copied from interface: Task

A good-citizen task should execute itself responsibly: it should know what to do in case of problems: for instance, fixable or irrelevant issues should usually just be logged used the InstallContext methods, when the user can fix them later on. The task could also potentially do backups of nodes it needs to modify extensively, so the user could refer to the backups in case of problem. In the event of an unrecoverable issue, the Task could also throw a TaskExecutionException, knowing that will cancel the whole module's installation, update and startup. If a TaskExecutionException must be thrown, keep in mind that the exception message will still be shown to the end user, so try to keep them human readable.

Throws:

TaskExecutionException

doExecute

protected abstract void doExecute(InstallContext installContext)
                           throws javax.jcr.RepositoryException,
                                  TaskExecutionException

Throws:

javax.jcr.RepositoryException
