Class ServicePaginators

  • @Generated(value="OracleSDKGenerator",
           comments="API Version: 0.0.1")
public class ServicePaginators
extends Object
    Collection of helper methods that can be used to provide an Iterable interface to any list operations of Service where multiple pages of data may be fetched.

    Two styles of iteration are supported:

    • Iterating over the Response objects returned by the list operation. These are referred to as ResponseIterators, and the methods are suffixed with ResponseIterator. For example: listUsersResponseIterator
    • Iterating over the resources/records being listed. These are referred to as RecordIterators, and the methods are suffixed with RecordIterator. For example: listUsersRecordIterator

    These iterables abstract away the need to write code to manually handle pagination via looping and using the page tokens. They will automatically fetch more data from the service when required.

    As an example, if we were using the ListUsers operation in IdentityService, then the Iterable returned by calling a ResponseIterator method would iterate over the ListUsersResponse objects returned by each ListUsers call, whereas the Iterable returned by calling a RecordIterator method would iterate over the User records and we don't have to deal with ListUsersResponse objects at all. In either case, pagination will be automatically handled so we can iterate until there are no more responses or no more resources/records available.

    • Method Detail

      • listServicesResponseIterator

        public Iterable<ListServicesResponse> listServicesResponseIterator​(ListServicesRequest request)
        Creates a new iterable which will iterate over the responses received from the listServices operation.

        This iterable will fetch more data from the server as needed.

        Parameters:
        request - a request which can be sent to the service operation
        Returns:
        an Iterable which can be used to iterate over the responses received from the service.

      • listServicesRecordIterator

        public Iterable<ServiceSummary> listServicesRecordIterator​(ListServicesRequest request)
        Creates a new iterable which will iterate over the ServiceSummary objects contained in responses from the listServices operation.

        This iterable will fetch more data from the server as needed.

        Parameters:
        request - a request which can be sent to the service operation
        Returns:
        an Iterable which can be used to iterate over the ServiceSummary objects contained in responses received from the service.
