Examples with AmsHeader org.apache.plc4x.java.ads.api.generic.AmsHeader used on opensource projects

Example 1 with AmsHeader

use of org.apache.plc4x.java.ads.api.generic.AmsHeader in project plc4x by apache.

the class Plc4x2AdsProtocolTest method syncInvoiceId.

private void syncInvoiceId() throws Exception {
    Field correlationBuilderField = SUT.getClass().getDeclaredField("correlationBuilder");
    correlationBuilderField.setAccessible(true);
    AtomicLong correlationBuilder = (AtomicLong) correlationBuilderField.get(SUT);
    AmsHeader amsHeader = amsPacket.getAmsHeader();
    Field invokeIdField = amsHeader.getClass().getDeclaredField("invokeId");
    Field modifiersField = Field.class.getDeclaredField("modifiers");
    modifiersField.setAccessible(true);
    modifiersField.setInt(invokeIdField, invokeIdField.getModifiers() & ~Modifier.FINAL);
    invokeIdField.setAccessible(true);
    invokeIdField.set(amsHeader, Invoke.of(correlationBuilder.get()));
}
