Class ActivationFilter

java.lang.Object

com.vmware.vapi.core.DecoratorApiProvider

com.vmware.vapi.std.activation.impl.ActivationFilter

All Implemented Interfaces:

ApiProvider

public final class ActivationFilter
extends DecoratorApiProvider

WARNING: Use only as a sample. The API is experimental and subject to change in future versions.

Server-side filter which intercepts method invocations and registers an activation identifier for each invocation into the AcitvationRegistry . As soon as the method invocation completes, the activation gets unregistered. If a duplication of identifiers occurs, the filter reports the StandardDataFactory.ALREADY_EXISTS standard error. The filter does not register activations for the methods of the activation manager.

This filter implementation is specific to the in-memory activation registry implementation in ActivationManagerImpl. If you write your own activation registry, you should also write your own activation filter.
