Class DefaultJmsTopicResolver

java.lang.Object
  org.mule.providers.jms.DefaultJmsTopicResolver

All Implemented Interfaces:

JmsTopicResolver

Direct Known Subclasses:

WeblogicJmsTopicResolver

public class DefaultJmsTopicResolver

extends Object

implements JmsTopicResolver

A default implementation of the resolver uses endpoint's resource info and Java's operator to detect JMS topics.

Field Summary

protected static Log

logger logger used by this class

Constructor Summary

DefaultJmsTopicResolver(JmsConnector connector)
Create an instance of the resolver.

Method Summary

protected void	checkInvariants(Destination destination) Perform some sanity checks, will complain in the log.
JmsConnector	getConnector() Getter for property 'connector'.
boolean	isTopic(Destination destination) Will use an operator.
boolean	isTopic(org.mule.umo.endpoint.UMOImmutableEndpoint endpoint) Will use endpoint's resource info to detect a topic, as in .
boolean	isTopic(org.mule.umo.endpoint.UMOImmutableEndpoint endpoint, boolean fallbackToEndpointProperties) Use endpoint configuration to detect a topic. Additionally, specify a fallback mechanism to search in endpoint's properties in case resource info yields . In case resource info returned no endpoint properties would be consulted.

Constructor Detail

DefaultJmsTopicResolver

public DefaultJmsTopicResolver(JmsConnector connector)

Create an instance of the resolver.

Parameters:

connector - owning connector

Method Detail

getConnector

public JmsConnector getConnector()

Getter for property 'connector'.

Returns:

Value for property 'connector'.

isTopic

public boolean isTopic(org.mule.umo.endpoint.UMOImmutableEndpoint endpoint)

Will use endpoint's resource info to detect a topic, as in . This method will call isTopic(org.mule.umo.endpoint.UMOImmutableEndpoint, boolean) with fallback flag set to true.

NOTE: When using topics, use the '.' (dot) symbol for subcontext separation, as opposed to '/'. Otherwise the resource info may not get properly translated for the topic endpoint due to the way URI's are parsed.

Specified by:

isTopic in interface JmsTopicResolver

Parameters:

endpoint - endpoint to test

Returns:

true if the endpoint has a topic configuration

isTopic

public boolean isTopic(org.mule.umo.endpoint.UMOImmutableEndpoint endpoint,
                       boolean fallbackToEndpointProperties)

Use endpoint configuration to detect a topic. Additionally, specify a fallback mechanism to search in endpoint's properties in case resource info yields . In case resource info returned no endpoint properties would be consulted.

Specified by:

isTopic in interface JmsTopicResolver

Parameters:

endpoint - endpoint to test

fallbackToEndpointProperties - whether to check endpoint's properties if resource info returned false

Returns:

true if endpoint's config tells it's a topic

isTopic

public boolean isTopic(Destination destination)

Will use an operator. Keep in mind that may fail for JMS systems implementing both a and in a single destination class implementation.

Specified by:

isTopic in interface JmsTopicResolver

Parameters:

destination - a jms destination to test

Returns:

if the destination is a topic

checkInvariants

protected void checkInvariants(Destination destination)

Perform some sanity checks, will complain in the log.

Parameters:

destination - destination to test
