Examples with BinaryEncoder org.apache.avro.io.BinaryEncoder used on opensource projects

Example 26 with BinaryEncoder

use of org.apache.avro.io.BinaryEncoder in project beam by apache.

the class AvroCoder method encode.

@Override
public void encode(T value, OutputStream outStream) throws IOException {
    // Get a BinaryEncoder instance from the ThreadLocal cache and attempt to reuse it.
    BinaryEncoder encoderInstance = ENCODER_FACTORY.directBinaryEncoder(outStream, encoder.get());
    // Save the potentially-new instance for reuse later.
    encoder.set(encoderInstance);
    writer.get().write(value, encoderInstance);
// Direct binary encoder does not buffer any data and need not be flushed.
}

Example 27 with BinaryEncoder

use of org.apache.avro.io.BinaryEncoder in project gora by apache.

the class AvroSerializerUtil method serializer.

@SuppressWarnings({ "unchecked", "rawtypes" })
public static <T> byte[] serializer(T value, Schema schema) throws IOException {
    SpecificDatumWriter writer = writerMap.get(schema.getFullName());
    if (writer == null) {

        writer = new SpecificDatumWriter(schema);
        writerMap.put(schema.getFullName(), writer);
    }
    BinaryEncoder encoderFromCache = encoders.get();
    ByteArrayOutputStream bos = new ByteArrayOutputStream();

    BinaryEncoder encoder = EncoderFactory.get().directBinaryEncoder(bos, null);
    if (encoderFromCache == null) {
        encoders.set(encoder);
    }
    //reset the buffers
    ByteArrayOutputStream os = outputStream.get();
    os.reset();
    writer.write(value, encoder);
    encoder.flush();
    byte[] byteValue = os.toByteArray();
    return byteValue;

Example 29 with BinaryEncoder

use of org.apache.avro.io.BinaryEncoder in project cdap by caskdata.
