Class NCSubscriber.AdminReuseCompatibilityHack

java.lang.Object

alma.acs.nc.NCSubscriber.AdminReuseCompatibilityHack

Enclosing class:

NCSubscriber<T extends org.omg.CORBA.portable.IDLEntity>

public static class NCSubscriber.AdminReuseCompatibilityHack
extends java.lang.Object

Encapsulates the hack of using a dummy ProxyType.PUSH_ANY proxy to mark a shared consumer admin used by NCSubscriber (or other next-gen subscribers), to distinguish it from non-reusable (subscriber-owned) admin objects as they are used by the old-generation subscribers.

AdminReuseCompatibilityHack

public AdminReuseCompatibilityHack(java.lang.String channelName,
                                   java.util.logging.Logger logger)

Method Detail

markAsSharedAdmin

public void markAsSharedAdmin(ConsumerAdmin consumerAdmin)
                       throws AcsJCORBAProblemEx

Creates a dummy proxy in the given consumer admin. This dummy proxy is not of a StructuredProxyPushSupplier, like the rest of the proxies that are created for the NC in the admin objects. This way we can recognize a shared consumer admin by looking at its proxies, and checking if their "MyType" property is ANY_EVENT. This hack is only needed while we are in transition between the old and new NC classes, and should get removed once the old classes are not used anymore (also not in C++ etc). In addition to using a unique proxy type, we also use a recognizable name, so that we can recognize the dummy proxy even when we only know its name, as it happens when working with the TAO MC statistics, see #isDummyProxy(String).

Throws:

AcsJCORBAProblemEx

isDummyProxy

public static boolean isDummyProxy(ProxySupplier proxy)

Checks if a given proxy supplier (as obtained through the regular NC API) is a dummy produced by this class.

Returns:

true if the given proxy is of type PUSH_ANY, which is used only to mark a shared consumer admin.

isSharedAdmin

public boolean isSharedAdmin(org.omg.CosNotifyChannelAdmin.ConsumerAdmin consumerAdmin)

Returns:

true if our consumer admin is shared. In the future when all NC libs are ported, this should always be the case.
