Method Details

addPathToSelection

PathQueryBuilder<T> addPathToSelection(String... path)

setToManyPathResultLimit

PathQueryBuilder<T> setToManyPathResultLimit(int limit)

To-Many paths are resolved with their own query and then merged with the main result set. By default, the size of the list of a to-many relation is unlimited. To limit the list (e.g. to prevent OOMs in some use cases), you can set a limit via this setter. If the limit is exceeded, a ToManyPathQueryResultOverflowException is thrown.
