Field Detail

map

protected java.util.Map map

Our lookup map of CacheActions

notificationUser

protected AuthUser notificationUser

The AuthUser which we use for authorization of outgoing CacheAction sends. This is initialized as needed.

Constructor Detail

CacheManagerNode

public CacheManagerNode()

Default ctor initializes our CacheAction map.

Method Detail

onStartup

protected void onStartup()
                  throws SandException

When we startup, we load our notification AuthUser if a username was specified. That way we are immediately ready for processing any incoming updates.

Overrides:

onStartup in class CacheManagerNodeBase

Throws:

SandException

onDelivery

public void onDelivery(SandUpdateMessage msg)
                throws SandException

If we get an incoming update message, and somebody is tracking the contained instance, then send out a CacheAction for it.

No notification is sent for an ADD action, since the instance can't have been cached yet. That's because the uniqueID hasn't been assigned until the ADD action completes, so it couldn't have been placed into a cache based on the ID.

Overrides:

onDelivery in class CacheManagerNodeBase

Throws:

SandException

onDelivery

public void onDelivery(CacheAction msg)
                throws SandException

If we get an incoming CacheAction, and somebody is registered for it, then send it on.

Overrides:

onDelivery in class CacheManagerNodeBase

Throws:

SandException

onReceive

protected CacheAction onReceive(CacheAction msg)
                         throws SandException

Override the onReceive processing to process this registration. Calls through to handleOnReceive.

Overrides:

onReceive in class CacheManagerNodeBase

Throws:

SandException

handleOnReceive

protected CacheAction handleOnReceive(CacheAction msg)
                               throws SandException

Deal with the registration. Since wildcard deregistrations involve iteration over the map, we are synchronized to avoid trying to process two registrations at once.

Throws:

SandException

doWildcardCleanup

protected void doWildcardCleanup(CacheAction msg)

Clean up any instances we have that match the source and the messageClass specified.
