Interface CPALookupManager

public interface CPALookupManager

The CPA cache service offers two kinds of lookup mechanisms. One is offered for such adapters, which need to start an own instance, for each Channel configuration. Such adapters use the LookupManager singleton class to read all known Channel configurations for their own adapter type from the cache at startup, to start an instance of the adapter for each Channel. These adapter types should also register themselves to the CallbackController, in order to be informed about new and deleted Channel configurations.

The other type of adapters has only one running instance, which can handle all messages, Channel-independent. These adapters need to retrieve the Channel configuration per Message at runtime, based on the addressing information in the header of the currently processed message. This is documented with the InboundRuntimeLookup and InboundRuntimeLookup objects.

The LookupManager allows to retrieve the CPA configuration objects either individually by the object type key (if known), or all CPA object of a given type, as a LinkedList. It also offers more advanced CPA object retrieval methods like getBindingByChannelId() and getChannelsByAdapterType(String adapterType).

adapterNamespace - The adapter namespace value.

direction - The direction value.

fromParty - The from party value.

fromService - The from service value.
