        @Override
        public IScalarEvaluator createScalarEvaluator(IHyracksTaskContext ctx) throws HyracksDataException {
            ITokenFactory tokenFactory = new UTF8WordTokenFactory();
            IBinaryTokenizer tokenizer = new DelimitedUTF8StringBinaryTokenizer(true, true, tokenFactory);
            return new WordTokensEvaluator(args, ctx, tokenizer, BuiltinType.ASTRING);

Example 2 with UTF8WordTokenFactory

use of org.apache.hyracks.storage.am.lsm.invertedindex.tokenizers.UTF8WordTokenFactory in project asterixdb by apache.

the class LSMInvertedIndexTestUtils method createWordInvIndexTestContext.

public static LSMInvertedIndexTestContext createWordInvIndexTestContext(LSMInvertedIndexTestHarness harness, InvertedIndexType invIndexType) throws IOException, HyracksDataException {
    ISerializerDeserializer[] fieldSerdes = getNonHashedIndexFieldSerdes(invIndexType);
