EventFilterImpl

public EventFilterImpl(int eventTypes,
                       Path absPath,

                       String[] uuids,
                       Set nodeTypeNames,
                       boolean noLocal)

Creates a new EventFilterImpl.

Parameters:

eventTypes - the event types this filter is interested in.

absPath - filter events that are below this path.

isDeep - whether this filter is applied deep.

uuids - the jcr:uuid of the nodes this filter allows.

nodeTypeNames - the Names of the already resolved node types this filter allows.

noLocal - whether this filter accepts local events or not.

Method Detail

accept

public boolean accept(Event event,
                      boolean isLocal)

If an implementation returns true the event will be included in the event bundle returned by RepositoryService.getEvents(Subscription, long). A return value of false indicates that the client is not interested in the event.

Specified by:

accept in interface EventFilter

Parameters:

event - the event in question.

isLocal - flag indicating whether this is a local event.

Returns:

true if the event is accepted by the filter; false otherwise.

public int getEventTypes()

Returns:

the event types this event filter accepts.

isDeep

public boolean isDeep()

Returns:

true if this event filter is deep.

getAbsPath

public Path getAbsPath()

Returns:

the path to the item where events are filtered.

getUUIDs

public String[] getUUIDs()

Returns:

the uuids of the nodes of this filter or null if this filter does not care about uuids.

getNodeTypeNames

public Set getNodeTypeNames()

Returns:

an unmodifiable set of node type names or null if this filter does not care about node types.

getNoLocal

public boolean getNoLocal()

Returns:

if this filter accepts local events.

toString
