Constructor Detail

MemoryOnlyStore

protected MemoryOnlyStore(CacheConfiguration cacheConfiguration,
                          MemoryStore authority,
                          SearchManager searchManager)

Create a MemoryOnlyStore

Parameters:

cacheConfiguration - the cache configuration

authority - the memory store

Method Detail

create

public static Store create(Ehcache cache,
                           Pool onHeapPool)

Create an instance of MemoryOnlyStore

Parameters:

cache - the cache

onHeapPool - the on heap pool

Returns:

an instance of MemoryOnlyStore

get

public Element get(Object key)

Gets an item from the cache.

Specified by:

get in interface Store

Overrides:

get in class FrontEndCacheTier<NullStore,MemoryStore>

getQuiet

public Element getQuiet(Object key)

Gets an Element from the Store, without updating statistics

Specified by:

getQuiet in interface Store

Overrides:

getQuiet in class FrontEndCacheTier<NullStore,MemoryStore>

Returns:

The element

setInMemoryEvictionPolicy

public void setInMemoryEvictionPolicy(Policy policy)

Sets the eviction policy strategy. The Store will use a policy at startup. The store may allow changing the eviction policy strategy dynamically. Otherwise implementations will throw an exception if this method is called.

Specified by:

setInMemoryEvictionPolicy in interface Store

Overrides:

setInMemoryEvictionPolicy in class FrontEndCacheTier<NullStore,MemoryStore>

Parameters:

policy - the new policy

getInMemoryEvictionPolicy

public Policy getInMemoryEvictionPolicy()

Specified by:

getInMemoryEvictionPolicy in interface Store

Overrides:

getInMemoryEvictionPolicy in class FrontEndCacheTier<NullStore,MemoryStore>

Returns:

the current eviction policy. This may not be the configured policy, if it has been dynamically set.

See Also:

Store.setInMemoryEvictionPolicy(Policy)

getMBean

public Object getMBean()

Optional implementation specific MBean exposed by the store.

Returns:

implementation specific management bean
