public class IntegrationContext extends Object
IntegrationContext is the base class for the integration context provided to the integration connector to provide access to open metadata services. Each integration service specializes this class to provide the method appropriate for the particular type of technology it is supporting. This base class supports the common methods available to all types of integration connectors.
