Class ExtendedElasticSearchIterator<T>

java.lang.Object

nl.vpro.elasticsearchclient.ElasticSearchIterator<T>

nl.vpro.elasticsearch.highlevel.ExtendedElasticSearchIterator<T>

All Implemented Interfaces:

AutoCloseable, Iterator<T>, nl.vpro.elasticsearch.ElasticSearchIteratorInterface<T>, nl.vpro.elasticsearch.ElasticSearchIteratorMXBean, CloseableIterator<T>, CountedIterator<T>

public class ExtendedElasticSearchIterator<T>
extends ElasticSearchIterator<T>

Like a low level ElasticSearchIterator, but with a method prepareSearchSource(java.lang.String...), so queries can be constructed using 'high level' syntax. All other things, like the type to adapt are still json only.

Since:

2.19
