org.apache.lucene.facet.complements.TotalFacetCountsCache.load()

Load {@link TotalFacetCounts} matching input parameters from the providedoutputFile and add them into the cache for the provided indexReader, taxonomy, and facetIndexingParams. If a {@link TotalFacetCounts} for theseparameters already exists in the cache, it will be replaced by the loaded one. @param inputFile file from which to read the data @param indexReader the documents index @param taxonomy the taxonomy index @param facetIndexingParams the facet indexing parameters @throws IOException on error


    TotalFacetCountsCache tfcc = TotalFacetCountsCache.getSingleton();
    File tmpFile = _TestUtil.createTempFile("test", "tmp", TEMP_DIR);
    tfcc.store(tmpFile, indexReader, taxoReader, iParams);
    tfcc.clear(); // not really required because TFCC overrides on load(), but in the test we need not rely on this.
    tfcc.load(tmpFile, indexReader, taxoReader, iParams);
    
    // now retrieve the one just loaded
    TotalFacetCounts totalCounts = tfcc.getTotalCounts(indexReader, taxoReader, iParams);
