To support notification mode, the Server SDK provides a
extension to synchronize with any client application. The PingDataSync engine processes the notification and makes
it available to the extension, which can be written in Java or Groovy. This generic
extension type can also be used for standard synchronization mode.
Similar to database synchronization, the custom server extension is stored in the <server-root>/lib/groovy-scripted-extensions directory (for Groovy-based extensions) or the jar file in the <server-root>/lib/extensions directory (for Java-based extensions) before configuring PingDataSync for notification mode. Groovy scripts are compiled and loaded at runtime.
The Server SDK's
SyncOperation interface represents a single
synchronized change from the Sync Source to the Sync Destination. The same
SyncOperation object exists from the time a change is detected,
through when the change is applied at the destination.
class (in the
com.unboundid.ldap.sdk.unboundidds package) has
high-level methods to work with the
ds-changelog-entry-key-attr-values attributes. The class is part of
the commercial edition of the LDAP SDK for Java and is installed automatically with
PingDataSync. For detailed information and
examples, see the LDAP SDK Javadoc.
