类 ConcurrentMapCacheManager

构造器详细资料

• ConcurrentMapCacheManager

  public ConcurrentMapCacheManager()

  Construct a dynamic ConcurrentMapCacheManager, lazily creating cache instances as they are being requested.

• ConcurrentMapCacheManager

  public ConcurrentMapCacheManager​(String... cacheNames)

  Construct a static ConcurrentMapCacheManager, managing caches for the specified cache names only.

方法详细资料

• setCacheNames

  public void setCacheNames​(Collection<String> cacheNames)

  Specify the set of cache names for this CacheManager's 'static' mode.

  The number of caches and their names will be fixed after a call to this method, with no creation of further cache regions at runtime.

  Calling this with a null collection argument resets the mode to 'dynamic', allowing for further creation of caches again.

• 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 ConcurrentHashMap itself not supporting null values. An internal holder object will be used to store user-level nulls.

  Note: A change of the null-value setting will reset all existing caches, if any, to reconfigure them with the new null-value requirement.

• isAllowNullValues

  public boolean isAllowNullValues()

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

• setStoreByValue

  public void setStoreByValue​(boolean storeByValue)

  Specify whether this cache manager stores a copy of each entry (true or the reference (false for all of its caches.

  Default is "false" so that the value itself is stored and no serializable contract is required on cached values.

  Note: A change of the store-by-value setting will reset all existing caches, if any, to reconfigure them with the new store-by-value requirement.

  从以下版本开始:

  4.3

• isStoreByValue

  public boolean isStoreByValue()

  Return whether this cache manager stores a copy of each entry or a reference for all its caches. If store by value is enabled, any cache entry must be serializable.

  从以下版本开始:

  4.3

• setBeanClassLoader

  public void setBeanClassLoader​(ClassLoader classLoader)

  从接口复制的说明: BeanClassLoaderAware
  Callback that supplies the bean class loader to a bean instance.

  Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean'sInitializingBean.afterPropertiesSet() method or a custom init-method.

  指定者:

  setBeanClassLoader 在接口中 BeanClassLoaderAware

  参数:

  classLoader - the owning class loader; may be null in which case a default ClassLoader must be used, for example the ClassLoader obtained via ClassUtils.getDefaultClassLoader()

• getCacheNames

  public Collection<String> getCacheNames()

  从接口复制的说明: CacheManager
  Get a collection of the cache names known by this manager.

  指定者:

  getCacheNames 在接口中 CacheManager

  返回:

  the names of all caches known by the cache manager

• getCache

  public Cache getCache​(String name)

  从接口复制的说明: CacheManager
  Get the cache associated with the given name.

  Note that the cache may be lazily created at runtime if the native provider supports it.

  指定者:

  getCache 在接口中 CacheManager

  参数:

  name - the cache identifier (must not be null)

  返回:

  the associated cache, or null if such a cache does not exist or could be not created

• createConcurrentMapCache

  protected Cache createConcurrentMapCache​(String name)

  Create a new ConcurrentMapCache instance for the specified cache name.

  参数:

  name - the name of the cache

  返回:

  the ConcurrentMapCache (or a decorator thereof)
