java.lang.Object

com.tangosol.util.Base

com.tangosol.util.MultiplexingMapListener<K,V>

com.tangosol.net.cache.ContinuousQueryCache.EventRouter<K,V>

Type Parameters:

K - the type parameter

V - the type parameter

All Implemented Interfaces:

MapListener<K,V>, EventListener

Enclosing class:

ContinuousQueryCache<K,V_BACK,V_FRONT>

protected class ContinuousQueryCache.EventRouter<K,V>
extends MultiplexingMapListener<K,V>

An EventRouter routes events from the internal cache of the ContinuousQueryCache to the client listeners, and it can do so asynchronously when appropriate.

Field Details

m_listener

protected MapListener<? super K,? super V> m_listener

The MapListener to route to.

f_fLite

protected final boolean f_fLite

Flag indicating MapEvent objects do not have to include the OldValue and NewValue property values in order to allow optimizations.

Constructor Details

EventRouter

public EventRouter(MapListener<? super K,? super V> listener,
 boolean fLite)

Construct an EventRouter to route events from the internal cache of the ContinuousQueryCache to the client listeners.

Parameters:

listener - a client listener

fLite - true to indicate that the MapEvent objects do not have to include the OldValue and NewValue property values in order to allow optimizations

Method Details

onMapEvent

protected void onMapEvent(MapEvent<K,V> evt)

Description copied from class: MultiplexingMapListener

Invoked when a map entry has been inserted, updated or deleted. To determine what action has occurred, use MapEvent.getId().

Specified by:

onMapEvent in class MultiplexingMapListener<K,V>

Parameters:

evt - the MapEvent carrying the insert, update or delete information

hashCode

public int hashCode()

Determine a hash value for the EventRouter object according to the general Object.hashCode() contract.

Overrides:

hashCode in class Object

Returns:

an integer hash value for this EventRouter

equals

public boolean equals(Object o)

Compare the EventRouter with another object to determine equality.

Overrides:

equals in class MultiplexingMapListener<K,V>

Returns:

true iff this ContinuousQueryCache.EventRouter and the passed object are equivalent listeners

toString

public String toString()

Produce a human-readable description of this EventRouter.

Overrides:

toString in class Object

Returns:

a String describing this EventRouter
