Description copied from class: Directive

Executes the query buffering all results in a list and returning that. This may be useful at the top level where the results are going to be retrieved entirely in a list anyway. Inside the query you should avoid using this as the intermediate results can become very large due to join operations. startQuery must have been called before calling this and endQuery after the query is done. If this is the top level directive you may have to do it manually. These call should propaget automaticall to all inner queries.

Throws:

QueryException
