Examples with IndexQueryStrategySPI org.locationtech.geowave.adapter.vector.index.IndexQueryStrategySPI used on opensource projects

Example 1 with IndexQueryStrategySPI

use of org.locationtech.geowave.adapter.vector.index.IndexQueryStrategySPI in project geowave by locationtech.

the class GeoWavePluginConfig method getIndexQueryStrategy.

public static IndexQueryStrategySPI getIndexQueryStrategy(final Map<String, ?> params) throws GeoWavePluginException {
    final Object param = params.get(QUERY_INDEX_STRATEGY_KEY);
    final String strategy = ((param == null) || param.toString().trim().isEmpty()) ? DEFAULT_QUERY_INDEX_STRATEGY : param.toString();
    final Iterator<IndexQueryStrategySPI> it = getInxexQueryStrategyList();
    while (it.hasNext()) {
        final IndexQueryStrategySPI spi = it.next();
        if (spi.toString().equals(strategy)) {
            return spi;
        }
    }
    // This would only get hit if the default query index strategy is removed from the spi registry.
    return null;
