Class AuditableFilter

java.lang.Object
  org.apache.cayenne.lifecycle.audit.AuditableFilter

All Implemented Interfaces:

DataChannelFilter

public class AuditableFilter
extends Object
implements DataChannelFilter

A DataChannelFilter that enables audit of entities annotated with Auditable and AuditableChild. Note that this filter relies on ChangeSetFilter presence in the DataDomain filter chain to be able to analyze ignored properties.

Since:

3.1

Method Detail

init

public void init(DataChannel channel)

Specified by:

init in interface DataChannelFilter

onQuery

public QueryResponse onQuery(ObjectContext originatingContext,
                             Query query,
                             DataChannelFilterChain filterChain)

Specified by:

onQuery in interface DataChannelFilter

onSync

public GraphDiff onSync(ObjectContext originatingContext,
                        GraphDiff changes,
                        int syncType,
                        DataChannelFilterChain filterChain)

Specified by:

onSync in interface DataChannelFilter

cleanupPostSync

protected void cleanupPostSync()

A method called at the end of every onSync(ObjectContext, GraphDiff, int, DataChannelFilterChain) invocation. This implementation uses it for cleaning up thread-local state of the filter. Subclasses may override it to do their own cleanup, and are expected to call super.

getParent

protected Persistent getParent(Persistent object)

isAuditableUpdate

protected boolean isAuditableUpdate(Object object,
                                    boolean child)
