Method Detail

iterator

default Iterator<E> iterator()

Executes the query and returns the matching objects as Iterator. This method may be overridden for database technology implementations that have native support for Iterator (unlike JPA). In such case this method is way more efficient if you only need to iterate the results to a specific point without the need to know the number of matches. If possible you shall prefer this method over Query.execute().

Specified by:

iterator in interface Iterable<E>

Returns:

an Iterator of the results.
