Class DefaultReferenceableDelegate

java.lang.Object

com.solacesystems.jms.DefaultReferenceableDelegate

All Implemented Interfaces:

SolReferenceableDelegate, DirObjectFactory, ObjectFactory

public class DefaultReferenceableDelegate
extends Object
implements SolReferenceableDelegate, ObjectFactory, DirObjectFactory

This is the default SolReferenceableDelegate used by the JMS API. This can be overridden by creating a SolReferenceableDelegate and calling SolJmsUtility.setReferenceableDelegate(SolReferenceableDelegate). This class does double duty in that it is the Object factory as well.

Property values that start with ‘#’ store ok but looking them up will throw a java.io.StreamCorruptedException. Properties are stored as property name – property value pairs (all as strings). The algorithm to get around the leading ‘#’ problem is this: If the property value has a leading ‘#’, append an ‘_’ to the property name and prepend an ‘_’ to the property value. So you could have (ClientDescription_=_#MyDescription). When the property values are looked up, if there exists an entry with a property name with an underscore on the end, I remove the first character from the property value.

getReference

public Reference getReference(Referenceable referenceable)
                       throws NamingException

Description copied from interface: SolReferenceableDelegate

The ConnectionFactory, XAConnection, Topic, or Queue is given as the referenceable argument and can be cast to a SolConnectionFactory, SolXAConnectionFactory, SolTopic, or SolQueue. If calling this returns null, the default implementation will be called.

Specified by:

getReference in interface SolReferenceableDelegate

Parameters:

referenceable - The SolConnectionFactory, SolXAConnectionFactory, SolTopic, or SolQueue that Referenceable.getReference() was called on

Returns:

The Reference, or null if you want to use the default implementation.

Throws:

NamingException - on error
