java.lang.Object
  extended byorg.activemq.ActiveMQTopicSession
All Implemented Interfaces:
java.lang.Runnable, javax.jms.Session, javax.jms.TopicSession

public class ActiveMQTopicSession
extends java.lang.Object
implements javax.jms.TopicSession

A TopicSession implementation that throws IllegalStateExceptions when Queue operations are attempted but which delegates to another TopicSession for all other operations. The ActiveMQSessions implement both Topic and Queue Sessions methods but the spec states that TopicSession should throw Exceptions if queue operations are attempted on it.

equals

public boolean equals(java.lang.Object arg0)
Description copied from class: java.lang.Object
Determine whether this Object is semantically equal to another Object.

There are some fairly strict requirements on this method which subclasses must follow:

  • It must be transitive. If a.equals(b) and b.equals(c), then a.equals(c) must be true as well.
  • It must be symmetric. a.equals(b) and b.equals(a) must have the same value.
  • It must be reflexive. a.equals(a) must always be true.
  • It must be consistent. Whichever value a.equals(b) returns on the first invocation must be the value returned on all later invocations.
  • a.equals(null) must be false.
  • It must be consistent with hashCode(). That is, a.equals(b) must imply a.hashCode() == b.hashCode(). The reverse is not true; two objects that are not equal may have the same hashcode, but that has the potential to harm hashing performance.

This is typically overridden to throw a java.lang.ClassCastException if the argument is not comparable to the class performing the comparison, but that is not a requirement. It is legal for a.equals(b) to be true even though a.getClass() != b.getClass(). Also, it is typical to never cause a java.lang.NullPointerException.

In general, the Collections API (java.util) use the equals method rather than the == operator to compare objects. However, java.util.IdentityHashMap is an exception to this rule, for its own good reasons.

The default implementation returns this == o.


getAcknowledgeMode

public int getAcknowledgeMode()
                       throws javax.jms.JMSException
Specified by:
getAcknowledgeMode in interface javax.jms.Session

getMessageListener

public javax.jms.MessageListener getMessageListener()
                                             throws javax.jms.JMSException
Specified by:
getMessageListener in interface javax.jms.Session

getTransacted

public boolean getTransacted()
                      throws javax.jms.JMSException
Specified by:
getTransacted in interface javax.jms.Session

hashCode

public int hashCode()
Description copied from class: java.lang.Object
Get a value that represents this Object, as uniquely as possible within the confines of an int.

There are some requirements on this method which subclasses must follow:

  • Semantic equality implies identical hashcodes. In other words, if a.equals(b) is true, then a.hashCode() == b.hashCode() must be as well. However, the reverse is not necessarily true, and two objects may have the same hashcode without being equal.
  • It must be consistent. Whichever value o.hashCode() returns on the first invocation must be the value returned on all later invocations as long as the object exists. Notice, however, that the result of hashCode may change between separate executions of a Virtual Machine, because it is not invoked on the same object.

Notice that since hashCode is used in java.util.Hashtable and other hashing classes, a poor implementation will degrade the performance of hashing (so don't blindly implement it as returning a constant!). Also, if calculating the hash is time-consuming, a class may consider caching the results.

The default implementation returns System.identityHashCode(this)


recover

public void recover()
             throws javax.jms.JMSException
Specified by:
recover in interface javax.jms.Session

rollback

public void rollback()
              throws javax.jms.JMSException
Specified by:
rollback in interface javax.jms.Session

run

public void run()
Description copied from interface: java.lang.Runnable
This method will be called by whoever wishes to run your class implementing Runnable. Note that there are no restrictions on what you are allowed to do in the run method, except that you cannot throw a checked exception.

Specified by:
run in interface javax.jms.Session

setMessageListener

public void setMessageListener(javax.jms.MessageListener listener)
                        throws javax.jms.JMSException
Specified by:
setMessageListener in interface javax.jms.Session

toString

public java.lang.String toString()
Description copied from class: java.lang.Object
Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

                 throws javax.jms.JMSException

unsubscribe in interface javax.jms.TopicSession
