Examples of org.apache.lucene.facet.complements.TotalFacetCountsCache.store()

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

Store the {@link TotalFacetCounts} matching input parameters into theprovided outputFile, making them available for a later call to {@link #load(File,IndexReader,TaxonomyReader,FacetIndexingParams)}. If these {@link TotalFacetCounts} are available in the cache, they are used.But if they are not in the cache, this call will first compute them (which will also add them to the cache). @param outputFile file to store in. @param indexReader the documents index @param taxonomy the taxonomy index @param facetIndexingParams the facet indexing parameters @throws IOException on error @see #load(File,IndexReader,TaxonomyReader,FacetIndexingParams)

    
    int[] intArray = new int[iParams.getPartitionSize()];


    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);
