All Implemented Interfaces:

com.oracle.common.base.Disposable, PartitionAwareBackingMap, java.util.Map

Enclosing class:

ObservableSplittingBackingCache

protected static class ObservableSplittingBackingCache.CapacityAwareMap

extends PartitionSplittingBackingMap

A subclass of PartitionSplittingBackingMap which allows an injected instance of ObservableSplittingBackingMap to be called immediately before inserting a value(s) in a partition map.

This class is intended for internal use only facilitating efficient use of PartitionSplittingBackingMap, by reducing the number of times the partitioned backing map is determined.

Field Detail

m_mapOuter

protected ObservableSplittingBackingCache m_mapOuter

The ObservableSplittingBackingMap used to call prepareUpdate.

Constructor Detail

ObservableSplittingBackingCache.CapacityAwareMap

protected ObservableSplittingBackingCache.CapacityAwareMap(BackingMapManager bmm,
                                                           java.lang.String sName)

Create a CapacityAwareMap.

Parameters:

bmm - a BackingMapManager that knows how to create and release the backing maps that this PartitionSplittingBackingMap is responsible for

sName - the cache name for which this backing map exists

Method Detail

putInternal

protected java.lang.Object putInternal(java.util.Map mapPart,
                                       java.lang.Object oKey,
                                       java.lang.Object oValue)

Put the key and value into a map representing a given partition.

Overrides:

putInternal in class PartitionSplittingBackingMap

Parameters:

mapPart - a partition map

oKey - oKey with which the specified value is to be associated

oValue - oValue to be associated with the specified oKey

Returns:

previous value associated with specified key, or null if there was no mapping for the key

putAllInternal

protected void putAllInternal(java.util.Map mapPart,
                              java.util.Map map)

Put all entries in mapUpdate into the provided map.

Overrides:

putAllInternal in class PartitionSplittingBackingMap

Parameters:

mapPart - a partition map

map - the Map containing the key/value pairings to put into mapPart

bind

protected void bind(ObservableSplittingBackingCache mapOuter)

Bind to the given ObservableSplittingBackingMap instance. This instance will have prepareUpdate invoked immediately prior to an insert to a partition map.

Parameters:

mapOuter - the map used to call prepareUpdate
