Interface DataChannelSyncFilter

All Known Implementing Classes:
CommitLogFilter, TransactionFilter
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface DataChannelSyncFilter
An interface of a filter that allows to intercept DataChannel sync operations. Sync filters allow to implement chains of custom processors around a DataChannel.

Example: 

public class MySyncFilter implements DataChannelSyncFilter {
    public GraphDiff onSync(ObjectContext originatingContext,
                            GraphDiff changes,
                            int syncType,
                            DataChannelSyncFilterChain filterChain) {
        System.out.println("Do something before sync");
        // process changes or return some custom diff
        GraphDiff diff = filterChain.onSync(originatingContext, changes, syncType);
        System.out.println("Do something after sync");
        return diff;
    }
}
