Method Detail

sync

public SyncToken sync(ObjectClass objectClass,
                      SyncToken token,
                      SyncResultsHandler handler,
                      OperationOptions options)

Description copied from interface: SyncApiOp

Request synchronization events--i.e., native changes to target objects.

This method will call the specified handler once to pass back each matching synchronization event. Once this method returns, this method will no longer invoke the specified handler.

Each synchronization event contains a token that can be used to resume reading events starting from that point in the event stream. In typical usage, a client will save the token from the final synchronization event that was received from one invocation of this sync() method and then pass that token into that client's next call to this sync() method. This allows a client to "pick up where he left off" in receiving synchronization events. However, a client can pass the token from any synchronization event into a subsequent invocation of this sync() method. This will return synchronization events (that represent native changes that occurred) immediately subsequent to the event from which the client obtained the token.

A client that wants to read synchronization events "starting now" can call SyncApiOp.getLatestSyncToken(org.identityconnectors.framework.common.objects.ObjectClass) and then pass that token into this sync() method.

Specified by:

sync in interface SyncApiOp

Parameters:

objectClass - The class of object for which to return synchronization events. Must not be null.

token - The token representing the last token from the previous sync. The SyncResultsHandler will return any number of SyncDelta objects, each of which contains a token. Should be null if this is the client's first call to the sync() method for this connector.

handler - The result handler. Must not be null.

options - Options that affect the way this operation is run. May be null.

Returns:

The sync token or null.

getLatestSyncToken

public SyncToken getLatestSyncToken(ObjectClass objectClass)

Description copied from interface: SyncApiOp

Returns the token corresponding to the most recent synchronization event for any instance of the specified object class.

An application that wants to receive synchronization events "starting now" --i.e., wants to receive only native changes that occur after this method is called-- should call this method and then pass the resulting token into the sync() method.

Specified by:

getLatestSyncToken in interface SyncApiOp

Parameters:

objectClass - the class of object for which to find the most recent synchronization event (if any).

Returns:

A token if synchronization events exist; otherwise null.
