Example 1 with ChannelWriter

use of com.ociweb.pronghorn.pipe.ChannelWriter in project PronghornPipes by oci-pronghorn.

the class TrieParserTest method testblobQuery.

@Test
public void testblobQuery() throws IOException {
    TrieParserReader reader = new TrieParserReader(3);
    TrieParser map = new TrieParser(16);
    map.setUTF8Value("12%b12", 33);
    // TrieParserReader reader, TrieParser trie,
    // byte[] source, int sourcePos, long sourceLength, int sourceMask,
    // final long unfoundResult) {
    long no_val = TrieParserReader.query(reader, map, "NoMatchonlong".getBytes(), 0, "No Match on long test.".length(), 15, -1);
    CharSequence test = "12abcd12";
    long val = reader.query(map, test);
    // below is testing cs.length()> reader.workingPipe.maxVarLen in Query()
    // mthod
    StringBuilder maxlengthtest = new StringBuilder();
    for (int i = 0; i < 2000; i++) {
        maxlengthtest.append(i);
    }
    long val1 = reader.query(map, maxlengthtest.toString());
    // Pipe<RawDataSchema> pipe = RawDataSchema.instance.newPipe(2, 64);
    // pipe.initBuffers();
    // 
    // int size = Pipe.addMsgIdx(pipe, RawDataSchema.MSG_CHUNKEDSTREAM_1);
    // DataOutputBlobWriter x =Pipe.outputStream(pipe);
    // DataOutputBlobWriter.openField(x);
    // 
    // reader.parseGather(reader, x,(byte) 'd'); // so will give 5. 5 bytes
    // until d is hit. if i put 'c' will return length of 4.
    ChannelWriter x = reader.blobQueryPrep(reader);
    x.append(test);
    long yy = reader.blobQuery(reader, map);
    x.close();
    // blobquery will return the mapping of the
    assertEquals(yy, 33);
// charsequence in the map
