Examples of org.apache.activemq.command.ActiveMQStreamMessage.writeBytes()

org.apache.activemq.command.ActiveMQStreamMessage.writeBytes()
Writes a byte array field to the stream message.

The byte array value is written to the message as a byte array field. Consecutively written byte array fields are treated as two distinct fields when the fields are read. @param value the byte array value to be written @throws JMSException if the JMS provider fails to write the message dueto some internal error. @throws MessageNotWriteableException if the message is in read-only mode.

        try {
            byte[] test = new byte[50];
            for (int i = 0; i < test.length; i++) {
                test[i] = (byte) i;
            }
            msg.writeBytes(test);
            msg.reset();
            byte[] valid = new byte[test.length];
            msg.readBytes(valid);
            for (int i = 0; i < valid.length; i++) {
                assertTrue(valid[i] == test[i]);
