Class AggregatedSearchQueryProvider

java.lang.Object

org.opennms.netmgt.flows.elastic.agg.AggregatedSearchQueryProvider

All Implemented Interfaces:

FilterVisitor<String>

public class AggregatedSearchQueryProvider
extends Object
implements FilterVisitor<String>

Here we store the search queries in the class-path in the form of Freemarker templates and use the templating to perform the parameter substitution. We could consider removing this in favor of using the High-level Elasticsearch client.
