Constructor Detail

JCacheCacheManager

public JCacheCacheManager()

Create a new JCacheCacheManager, setting the target JCache CacheManager through the setCacheManager(javax.cache.CacheManager) bean property.

JCacheCacheManager

public JCacheCacheManager(CacheManager cacheManager)

Create a new JCacheCacheManager for the given backing JCache.

Parameters:

cacheManager - the backing JCache javax.cache.CacheManager

Method Detail

setCacheManager

public void setCacheManager(javax.cache.CacheManager cacheManager)

Set the backing JCache javax.cache.CacheManager.

getCacheManager

public javax.cache.CacheManager getCacheManager()

Return the backing JCache javax.cache.CacheManager.

setAllowNullValues

public void setAllowNullValues(boolean allowNullValues)

Specify whether to accept and convert null values for all caches in this cache manager.

Default is "true", despite JSR-107 itself not supporting null values. An internal holder object will be used to store user-level nulls.

isAllowNullValues

public boolean isAllowNullValues()

Return whether this cache manager accepts and converts null values for all of its caches.

afterPropertiesSet

public void afterPropertiesSet()

Description copied from interface: InitializingBean

Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

Specified by:

afterPropertiesSet in interface InitializingBean

Overrides:

afterPropertiesSet in class AbstractCacheManager

loadCaches

protected java.util.Collection<Cache> loadCaches()

Description copied from class: AbstractCacheManager

Load the initial caches for this cache manager.

Called by AbstractCacheManager.afterPropertiesSet() on startup. The returned collection may be empty but must not be null.

Specified by:

loadCaches in class AbstractCacheManager

getMissingCache

protected Cache getMissingCache(java.lang.String name)

Description copied from class: AbstractCacheManager

Return a missing cache with the specified name or null if such cache does not exist or could not be created on the fly.

Some caches may be created at runtime in the native provided. If a lookup by name does not yield any result, a subclass gets a chance to register such a cache at runtime. The returned cache will be automatically added to this instance.

Overrides:

getMissingCache in class AbstractCacheManager

Parameters:

name - the name of the cache to retrieve

Returns:

the missing cache or null if no such cache exists or could be created
