Examples of org.apache.lucene.document.FieldSelector

org.apache.lucene.document.FieldSelector
Similar to a {@link java.io.FileFilter}, the FieldSelector allows one to make decisions about what Fields get loaded on a {@link Document} by {@link org.apache.lucene.index.IndexReader#document(int,org.apache.lucene.document.FieldSelector)}

        for (int i = 0; i < bin.length; i++) {
          assertEquals(bin[i], data1[i + b1.getBinaryOffset()]);
        }
        Set lazyFields = new HashSet();
        lazyFields.add("bin1");
        FieldSelector sel = new SetBasedFieldSelector(new HashSet(), lazyFields);
        doc = reader.document(reader.maxDoc() - 1, sel);
        Fieldable[] fieldables = doc.getFieldables("bin1");
        assertNotNull(fieldables);
        assertEquals(1, fieldables.length);
