use of org.apache.metron.indexing.dao.MultiIndexDao in project metron by apache.

the class ElasticsearchMetaAlertDao method init.

/**
 * Initializes this implementation by setting the supplied IndexDao and also setting a separate ElasticsearchDao.
 * This is needed for some specific Elasticsearch functions (looking up an index from a GUID for example).
 * @param indexDao The DAO to wrap for our queries
 * @param threatSort The summary aggregation of the child threat triage scores used
 *                   as the overall threat triage score for the metaalert. This
 *                   can be either max, min, average, count, median, or sum.
