Example 75 with QpidByteBuffer

use of org.apache.qpid.server.bytebuffer.QpidByteBuffer in project qpid-broker-j by apache.

the class LinkStoreUtils method objectToAmqpBytes.

public static byte[] objectToAmqpBytes(final Object object) {
    ValueWriter valueWriter = DESCRIBED_TYPE_REGISTRY.getValueWriter(object);
    int encodedSize = valueWriter.getEncodedSize();
    try (QpidByteBuffer qpidByteBuffer = QpidByteBuffer.allocate(encodedSize)) {
        valueWriter.writeToBuffer(qpidByteBuffer);
        return qpidByteBuffer.array();
    }
