Class CoarseSessionAttributesFactory<C,V>

java.lang.Object

org.wildfly.clustering.session.infinispan.embedded.attributes.CoarseSessionAttributesFactory<C,V>

Type Parameters:

C - the session manager context type

V - the cache value type

All Implemented Interfaces:

AutoCloseable, CacheEntryCreator<String,Map<String,Object>,Void>, CacheEntryLocator<String,Map<String,Object>>, CacheEntryRemover<String>, ImmutableSessionAttributesFactory<Map<String,Object>>, SessionAttributesFactory<C,Map<String,Object>>

public class CoarseSessionAttributesFactory<C,V>
extends Object
implements SessionAttributesFactory<C,Map<String,Object>>

SessionAttributesFactory for coarse granularity sessions, where all session attributes are stored in a single cache entry. This implementation is safe for attributes that strongly reference each other.

Method Details

close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface SessionAttributesFactory<C,V>

createValueAsync

public CompletionStage<Map<String,Object>> createValueAsync(String id,
 Void context)

Description copied from interface: CacheEntryCreator

Creates a value in the cache, if it does not already exist.

Specified by:

createValueAsync in interface CacheEntryCreator<String,Map<String,Object>,Void>

Parameters:

id - the cache entry identifier.

context - the context of the created value

Returns:

the new value, or the existing value the cache entry already exists.

findValueAsync

public CompletionStage<Map<String,Object>> findValueAsync(String id)

Description copied from interface: CacheEntryLocator

Locates the value in the cache with the specified identifier.

Specified by:

findValueAsync in interface CacheEntryLocator<C,V>

Parameters:

id - the cache entry identifier

Returns:

the value of the cache entry, or null if not found.

tryValueAsync

public CompletionStage<Map<String,Object>> tryValueAsync(String id)

Description copied from interface: CacheEntryLocator

Returns the value for the specified key, if possible without contention.

Specified by:
