示例1: findNestedObjectMapper

import org.apache.lucene.search.Query; //導入方法依賴的package包/類
/**
 * Returns the best nested {@link ObjectMapper} instances that is in the scope of the specified nested docId.
 */
public ObjectMapper findNestedObjectMapper(int nestedDocId, SearchContext sc, LeafReaderContext context) throws IOException {
    ObjectMapper nestedObjectMapper = null;
    for (ObjectMapper objectMapper : objectMappers().values()) {
        if (!objectMapper.nested().isNested()) {
            continue;

        Query filter = objectMapper.nestedTypeFilter();
        if (filter == null) {
            continue;
        }
        // We can pass down 'null' as acceptedDocs, because nestedDocId is a doc to be fetched and
        // therefor is guaranteed to be a live doc.
        final Weight nestedWeight = filter.createWeight(sc.searcher(), false);
        Scorer scorer = nestedWeight.scorer(context);
