Example 5 with UnknownAlternateBindingException

use of org.apache.qpid.server.virtualhost.UnknownAlternateBindingException in project qpid-broker-j by apache.

the class AbstractQueue method validateOrCreateAlternateBinding.

private void validateOrCreateAlternateBinding(final Queue<?> queue, final boolean mayCreate) {
    Object value = queue.getAttribute(ALTERNATE_BINDING);
    if (value instanceof AlternateBinding) {
        AlternateBinding alternateBinding = (AlternateBinding) value;
        String destinationName = alternateBinding.getDestination();
        MessageDestination messageDestination = _virtualHost.getAttainedMessageDestination(destinationName, mayCreate);
        if (messageDestination == null) {
            throw new UnknownAlternateBindingException(destinationName);
        } else if (messageDestination == this) {
            throw new IllegalConfigurationException(String.format("Cannot create alternate binding for '%s' : Alternate binding destination cannot refer to self.", getName()));
        } else if (isDurable() && !messageDestination.isDurable()) {
            throw new IllegalConfigurationException(String.format("Cannot create alternate binding for '%s' : Alternate binding destination '%s' is not durable.", getName(), destinationName));
