Interface CacheBuilder<K,V>

Type Parameters:

K - the key type

V - the value type

public interface CacheBuilder<K,V>

A CacheBuilder is used for creating Caches. A CacheBuilder is created by CacheManager.createCacheBuilder(String) and is associated with that manager. Additional configuration methods may be available on a builder instance by casting to a concrete implementation.

Method Detail

build

Cache<K,V> build()

Create an instance of the named Cache.

The Cache will be created, added to the caches controlled by its associated CacheManager and started. If there is an existing Cache of the same name associated with this CacheManager when build is invoked, the old Cache will be stopped.

Returns:

a new instance of the named cache

Throws:

InvalidConfigurationException - thrown if the configuration is invalid. Examples include if read through has been set to true but no cache loader is specified, or if no cache writer is specified but write through has been set.

CacheException - if a cache with that name already exists or there was an error adding the cache to the CacheManager

CacheManager.createCacheBuilder(String)

setCacheLoader

CacheBuilder<K,V> setCacheLoader(CacheLoader<K,? extends V> cacheLoader)

Sets the cache loader.

Parameters:

cacheLoader - the CacheLoader

Returns:

the builder

Throws:

NullPointerException - if cacheLoader is null.

setCacheWriter

CacheBuilder<K,V> setCacheWriter(CacheWriter<? super K,? super V> cacheWriter)

Sets the cache writer.

Parameters:

cacheWriter - the CacheWriter

Returns:

the builder

Throws:

NullPointerException - if cacheWriter is null.

registerCacheEntryListener

CacheBuilder<K,V> registerCacheEntryListener(CacheEntryListener<K,V> cacheEntryListener)

Registers a listener. Can be invoked multiple times.

Parameters:

cacheEntryListener - the listener

Returns:

the builder

Throws:

NullPointerException - if any of the arguments are null.

setStoreByValue

CacheBuilder<K,V> setStoreByValue(boolean storeByValue)

Sets whether the cache is store-by-value cache.

Parameters:

storeByValue - the value for storeByValue

Returns:

the builder

Throws:

IllegalStateException - if the configuration can no longer be changed

InvalidConfigurationException - if the cache does not support store by reference

CacheConfiguration.isStoreByValue()

setTransactionEnabled

CacheBuilder<K,V> setTransactionEnabled(IsolationLevel isolationLevel,
                                        Mode mode)

Sets whether transaction are enabled for this cache.

Parameters:

isolationLevel - - the isolation level for this cache

mode - - the mode (Local or XA) for this cache

Returns:

the builder

Throws:

IllegalArgumentException - if the cache does not support transactions, or an attempt is made to set the isolation level to IsolationLevel.NONE or the mode to Mode.NONE.

CacheConfiguration.isTransactionEnabled()

setStatisticsEnabled

CacheBuilder<K,V> setStatisticsEnabled(boolean enableStatistics)

Sets whether statistics gathering is enabled on this cache.

Parameters:

enableStatistics - true to enable statistics, false to disable

Returns:

the builder

See Also:

CacheConfiguration.setStatisticsEnabled(boolean)

setReadThrough

CacheBuilder<K,V> setReadThrough(boolean readThrough)

Sets whether the cache is a read-through cache. If so a CacheLoader should be configured.

Parameters:

readThrough - the value for readThrough

Returns:

the builder

setWriteThrough

CacheBuilder<K,V> setWriteThrough(boolean writeThrough)

Whether the cache is a write-through cache. A CacheWriter should be configured.

Parameters:

writeThrough - set to true for a write-through cache

Returns:

the builder

setExpiry

CacheBuilder<K,V> setExpiry(CacheConfiguration.ExpiryType type,
                            CacheConfiguration.Duration duration)

Sets the cache expiration

Parameters:

type - whether based on creation/modification or last access time

duration - the amount of time
