Method Detail

ownedByMessageDestinationRef

public boolean ownedByMessageDestinationRef()

True if the owner is a message destination reference.

Specified by:

ownedByMessageDestinationRef in interface MessageDestinationReferencer

getMessageDestinationRefOwner

public MessageDestinationReferenceDescriptor getMessageDestinationRefOwner()

Get the descriptor for the message destination reference owner.

Specified by:

getMessageDestinationRefOwner in interface MessageDestinationReferencer

ownedByMessageBean

public boolean ownedByMessageBean()

True if the owner is a message-driven bean.

Specified by:

ownedByMessageBean in interface MessageDestinationReferencer

getMessageBeanOwner

public EjbMessageBeanDescriptor getMessageBeanOwner()

Get the descriptor for the message-driven bean owner.

Specified by:

getMessageBeanOwner in interface MessageDestinationReferencer

isLinkedToMessageDestination

public boolean isLinkedToMessageDestination()

True if this reference has been resolved to a valid MessageDestination object.

Specified by:

isLinkedToMessageDestination in interface MessageDestinationReferencer

Returns:

true if this referencer is linked to a message destination and false otherwise.

getMessageDestinationLinkName

public String getMessageDestinationLinkName()

Description copied from interface: MessageDestinationReferencer

Gets the link name of the reference. Points to the associated message destination within the J2EE application. Can be NULL if link is not set.

Specified by:

getMessageDestinationLinkName in interface MessageDestinationReferencer

Returns:

the link name of the message destination to which I refer NOTE that this "link name" is potentially different from the actual name of the target message destination, since the message destination could be defined in a different module.

setMessageDestinationLinkName

public void setMessageDestinationLinkName(String linkName)

Sets the name of the message destination to which I refer. NOTE : Does *NOT* attempt to resolve link name. Use alternate version of setMessageDestinationLinkName or resolveLink if link resolution is required.

Specified by:

setMessageDestinationLinkName in interface MessageDestinationReferencer

setMessageDestinationLinkName

public MessageDestinationDescriptor setMessageDestinationLinkName(String linkName,
                                                                  boolean resolve)

Sets the name of the message destination to which I refer.

Specified by:

setMessageDestinationLinkName in interface MessageDestinationReferencer

Parameters:

resolve - if true, *try* to resolve link to the target message destination.

Returns:

MessageDestination to which link was resolved, or null if link name resolution failed.

resolveLinkName

public MessageDestinationDescriptor resolveLinkName()

Try to resolve the current link name value to a MessageDestination object.

Specified by:

resolveLinkName in interface MessageDestinationReferencer

Returns:

MessageDestination to which link was resolved, or null if link name resolution failed.

getMessageDestination

public MessageDestinationDescriptor getMessageDestination()

Specified by:

getMessageDestination in interface MessageDestinationReferencer

Returns:

the message destination to which I refer. Can be NULL.

setMessageDestination

public void setMessageDestination(MessageDestinationDescriptor newMsgDest)

Specified by:

setMessageDestination in interface MessageDestinationReferencer

Parameters:

messageDestiation - the message destination to which I refer.
