java.lang.Object

org.openspaces.core.space.cache.AbstractLocalCacheSpaceFactoryBean

org.openspaces.core.space.cache.LocalViewSpaceFactoryBean

public class LocalViewSpaceFactoryBean
extends AbstractLocalCacheSpaceFactoryBean

The space local view proxy maintains a subset of the master space's data, allowing the client to read distributed data without any remote operations.

Data is streamed into the client view in an implicit manner - as opposed to local cache data (LocalCacheSpaceFactoryBean), that is loaded into the client on- demand, and later updated or evicted.

The local view is defined via a filter (setLocalViews(java.util.List) localViews) - as opposed to the local cache that caches data at the client side only after the data has been read

public LocalViewSpaceFactoryBean()

Method Detail

isSingleton

public boolean isSingleton()

Returns true since this bean is a singleton.

Specified by:

isSingleton in interface org.springframework.beans.factory.FactoryBean

Overrides:

isSingleton in class AbstractLocalCacheSpaceFactoryBean

getObject

public Object getObject()

Returns an IJSpace that is the local cache wrapping the master proxy set using setSpace(com.j_spaces.core.IJSpace).

getObjectType
