Example 6 with InputStreamSources

use of com.facebook.presto.orc.stream.InputStreamSources in project presto by prestodb.

the class SliceDictionarySelectiveReader method startStripe.

@Override
public void startStripe(Stripe stripe) {
    InputStreamSources dictionaryStreamSources = stripe.getDictionaryStreamSources();
    stripeDictionaryDataStreamSource = dictionaryStreamSources.getInputStreamSource(streamDescriptor, DICTIONARY_DATA, ByteArrayInputStream.class);
    stripeDictionaryLengthStreamSource = dictionaryStreamSources.getInputStreamSource(streamDescriptor, LENGTH, LongInputStream.class);
    stripeDictionarySize = stripe.getColumnEncodings().get(streamDescriptor.getStreamId()).getColumnEncoding(streamDescriptor.getSequence()).getDictionarySize();
    stripeDictionaryOpen = false;
    presentStreamSource = missingStreamSource(BooleanInputStream.class);
    dataStreamSource = missingStreamSource(LongInputStream.class);
