Request Provisioning server to perform data retrieval (search/sort).
Send update (creation/replacement/deletion) requests for data stored in the Provisioning server. An application can insert a new database record, update the values of a set of selected fields within a domain, or update the values of a selected set of fields confined by a database search result.
Monitor data changes during runtime by providing client registration and notification of data updates. An application can request the Provisioning server to notify it whenever some data in a domain or a specific database record is changed. The application provides a callback function to
PSLib. When changes occur in the domain or record of interest, the Provisioning server sends a message toPSLib, which invokes the registered callback method of the client.Parse responses from queries sent to the Provisioning server and cache the XML content in a searchable structure.
Provide a set of simple, generic APIs for clients to access and manipulate individual ...
