19 * This context is registered with MD-SAL as a routed RPC provider for the inventory node backed by this switch and
20 * tracks the state of any user requests and how they map onto protocol requests. It uses
21 * {@link org.opendaylight.openflowplugin.api.openflow.device.RequestContext} to perform requests.

27 <S extends RpcService> void registerRpcServiceImplementation(Class<S> serviceClass, S serviceInstance);
30 * Method adds request to request queue which has limited quota. After number of requests exceeds quota limit
31 * future will be done immediately and will contain information about exceeded request quota.
35 <T extends DataObject> SettableFuture<RpcResult<T>> storeOrFail(RequestContext data);
38 * Method for setting request quota value. When the Request Context quota is exceeded, incoming RPCs fail
39 * immediately, with a well-defined error.

43 void setRequestContextQuota(int maxRequestsPerDevice);
45 void forgetRequestContext(RequestContext requestContext);
48 * Method provides device context.
51 DeviceContext getDeviceContext();
54 * Method returns new request context for current request.
