This extension feature helps developer to provide information regarding pagination from the host system. This will be typically used in inquiry transactions where large number of records is expected in response. To display such large data, pagination approach is used in user interface to display limited number of records at a time. Based on user action the subsequent records are fetched. The pagination information provided by this extension can be used in UI layer to display pagination response as per developer’s requirement.

The supported extension parameters are:

• more : a Boolean field to represent if any more data is available in response
• totalRecords : an Integer containing total number of records for the respective query
• startSequence : an Integer which can typically contain the sequence number of the first record in the next pagination records list.

To use the above extension following steps need to be executed.

• The response DTO of service should implement ‘com.ofss.digx.app.dto.Ipaginable’ interface and should override all the methods of this interface.
• Add following snippet in respective extxface adapter after calling 'HostAdapterManager.processRequest(hostRequest)'.
