Examples with Filter org.apache.activemq.artemis.core.filter.Filter used on opensource projects

Example 1 with Filter

use of org.apache.activemq.artemis.core.filter.Filter in project activemq-artemis by apache.

the class PostOfficeImpl method addBinding.

// TODO - needs to be synchronized to prevent happening concurrently with activate()
// (and possible removeBinding and other methods)
// Otherwise can have situation where createQueue comes in before failover, then failover occurs
// and post office is activated but queue remains unactivated after failover so delivery never occurs
// even though failover is complete
@Override
public synchronized void addBinding(final Binding binding) throws Exception {
    if (server.hasBrokerPlugins()) {
        server.callBrokerPlugins(plugin -> plugin.beforeAddBinding(binding));
