All Implemented Interfaces:

```
public class FilterImpl
extends Object
implements Filter
```
This class implements an ActiveMQ Artemis filter ActiveMQ Artemis filters have the same syntax as JMS 1.1 selectors, but the identifiers are different. Valid identifiers that can be used are: AMQPriority - the priority of the message AMQTimestamp - the timestamp of the message AMQDurable - "DURABLE" or "NON_DURABLE" AMQExpiration - the expiration of the message AMQSize - the encoded size of the full message in bytes AMQUserID - the user specified ID string (if any) Any other identifiers that appear in a filter expression represent header values for the message String values must be set as SimpleString, not java.lang.String (see JBMESSAGING-1307). Derived from JBoss MQ version by
