Interface AdapterRegistry

public interface AdapterRegistry

Provides an interface to register an adapter with the Adapter Framework. Information provided during the adapter registration include so-called adapter capabilities, which offer a means to announce certain adapter features (such as the support of push-based monitoring) to the Adapter Framework, as well as callbacks implemented by an adapter, which are invoked by the Adapter Framework on various occasions during the adapter's runtime.

An adapter must not register itself with the AdapterRegistry as well as the MonitorManager (which is superseded by the com.sap.aii.af.service.administration.api.* API) at the same time. Doing so will throw an AdapterAlreadyRegisteredException.

Important: Always unregister an adapter by invoking the unregisterAdapter method before the adapter terminates so that any object references within the Adapter Framework service pointing to the adapter can be freed.

An instance of this interface can be obtained using AdapterRegistryFactory.

Usage:

AdapterRegistryFactory.getInstance().getAdapterRegistry().
registerAdapter(ADAPTER_NAMESPACE, ADAPTER_NAME, new AdapterCapability[] { <adapter capabilities> }, new AdapterCallback[] { <adapter callbacks> });

Method Detail

registerAdapter

void registerAdapter(String adapterNamespace,
                     String adapterName,
                     AdapterCapability[] capabilities,
                     AdapterCallback[] callbacks)
              throws AdapterAlreadyRegisteredException,
                     AdapterCapabilityMismatchException,
                     AdapterCallbackUnknownException,
                     AdapterCallbackDuplicateException

Registers an adapter with the Adapter Framework.

Information constituting the registration are a set of adapter capabilities as well as a set of callbacks into the adapter implementation. Examples of callbacks that can be registered are the ChannelLifecycleCallback as well as the LocalizationCallback interfaces.

Parameters:

adapterNamespace - the adapter's namespace

adapterName - the adapter's name (or type)

capabilities - an array of AdapterCapability constants describing the capabilities supported by the adapter

callbacks - the adapter callbacks to be registered

Throws:

AdapterAlreadyRegisteredException - if the adapter is already registered

AdapterCallbackUnknownException - if any of the supplied AdapterCallback instances implements an interface/callback unknown to the Adapter Framework

AdapterCapabilityMismatchException - if the specified capabilities do not match the supplied callbacks or vide versa

AdapterCallbackDuplicateException - if any callback interface is provided more than once in the callbacks array

unregisterAdapter

void unregisterAdapter(String adapterNamespace,
                       String adapterName)
                throws AdapterNotRegisteredException

Unregisters an adapter from the Adapter Framework.

Parameters:

adapterNamespace - the adapter's namespace

adapterName - the adapter's name (or type)

Throws:

AdapterNotRegisteredException - if the adapter was not registered using registerAdapter prior to invoking this method
