public abstract class QueryTask
extends AbstractRepositoryTask

An abstract task to perform operations on nodes returned by a given query. Keep in mind that results returned by a query will reflect the current content of the repository, NOT of your session; i.e if a previous task modified a property, the query might still return the node as if it had the previous value.

Because the limitation above can lead to incomplete updates, we encourage usage of the NodeVisitorTask instead.
