This package provides an implementation of the authorization-related interfaces defined by the org.onap.dmaap.datarouter.authz package, intended for use with the provisioning server for Data Router Release 1. In DR R1, we do not have an external policy engine, so this implementation performs the authorization locally.

In order to perform the authorization, this package needs access to provisioning data about feeds and subscriptions. This package defines an interface (org.onap.dmaap.datarouter.authz.impl.ProvDataProvider) through which it expects to get this data. The provisioning server code must provide an implementation of this interface.

A software component that wishes to use this implementation must:

• Provide an implementation of the org.onap.dmaap.datarouter.authz.impl.ProvDataProvider interface.
• Create an instance of the ProvDataProvider implementation.
• Create an instance of the org.onap.dmaap.datarouter.authz.impl.ProvAuthorizer class defined in this package, passing it an instance of the ProvDataProvider implementation.

ProvDataProvider dataProv = new MyDataProvider();
Authorizer authz = new ProvAuthorizer(dataProv);
