Interface CompleteConfiguration<K,V>

Type Parameters:

K - the type of keys maintained the cache

V - the type of cached values

All Superinterfaces:

Configuration<K,V>, Serializable

All Known Implementing Classes:

MutableConfiguration

public interface CompleteConfiguration<K,V>
extends Configuration<K,V>, Serializable

A read-only representation of the complete JCache Cache configuration.

The properties provided by instances of this interface are used by CacheManagers to configure Caches.

Implementations of this interface must override Object.hashCode() and Object.equals(Object) as CompleteConfigurations are often compared at runtime.

Since:

1.0

Method Details

isReadThrough

boolean isReadThrough()

Determines if a Cache should operate in read-through mode.

When in "read-through" mode, cache misses that occur due to cache entries not existing as a result of performing a "get" will appropriately cause the configured CacheLoader to be invoked.

The default value is false.

Returns:

true when a Cache is in "read-through" mode.

See Also:

• getCacheLoaderFactory()

isWriteThrough

boolean isWriteThrough()

Determines if a Cache should operate in write-through mode.

When in "write-through" mode, cache updates that occur as a result of performing "put" operations called via one of Cache.put(Object, Object), Cache.getAndRemove(Object), Cache.removeAll(), Cache.getAndPut(Object, Object) Cache.getAndRemove(Object), Cache.getAndReplace(Object, Object), Cache.invoke(Object, javax.cache.processor.EntryProcessor, Object...), Cache.invokeAll(java.util.Set, javax.cache.processor.EntryProcessor, Object...) will appropriately cause the configured CacheWriter to be invoked.

The default value is false.

Returns:

true when a Cache is in "write-through" mode.

See Also:

• getCacheWriterFactory()

isStatisticsEnabled

boolean isStatisticsEnabled()

Checks whether statistics collection is enabled in this cache.

The default value is false.

Returns:

true if statistics collection is enabled

isManagementEnabled

boolean isManagementEnabled()

Checks whether management is enabled on this cache.

The default value is false.

Returns:

true if management is enabled

getCacheEntryListenerConfigurations

Iterable<CacheEntryListenerConfiguration<K,V>> getCacheEntryListenerConfigurations()

Obtains the CacheEntryListenerConfigurations for CacheEntryListeners to be configured on a Cache.

Returns:

an Iterable over the CacheEntryListenerConfigurations

getCacheLoaderFactory

Factory<CacheLoader<K,V>> getCacheLoaderFactory()

Gets the Factory for the CacheLoader, if any.

A CacheLoader should be configured for "Read Through" caches to load values when a cache miss occurs using either the Cache.get(Object) and/or Cache.getAll(java.util.Set) methods.

The default value is null.

Returns:

the Factory for the CacheLoader or null if none has been set.

getCacheWriterFactory

Factory<CacheWriter<? super K, ? super V>> getCacheWriterFactory()

Gets the Factory for the CacheWriter, if any.

The default value is null.

Returns:

the Factory for the CacheWriter or null if none has been set.

getExpiryPolicyFactory

Factory<ExpiryPolicy> getExpiryPolicyFactory()

Gets the Factory for the ExpiryPolicy to be used for caches.

The default value is a Factory that will produce a EternalExpiryPolicy instance.

Returns:

the Factory for ExpiryPolicy (must not be null)
