Class ConcurrentMapCacheManager

java.lang.Object

org.springframework.cache.concurrent.ConcurrentMapCacheManager

All Implemented Interfaces:

CacheManager

public class ConcurrentMapCacheManager
extends java.lang.Object
implements CacheManager

CacheManager implementation that lazily builds ConcurrentMapCache instances for each getCache(java.lang.String) request. Also supports a 'static' mode where the set of cache names is pre-defined through setCacheNames(java.util.Collection<java.lang.String>), with no dynamic creation of further cache regions at runtime.

Since:

3.1

Constructor Detail

ConcurrentMapCacheManager

public ConcurrentMapCacheManager()

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

ConcurrentMapCacheManager

public ConcurrentMapCacheManager(java.lang.String... cacheNames)

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

Method Detail

setCacheNames

public void setCacheNames(java.util.Collection<java.lang.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.

getCacheNames

public java.util.Collection<java.lang.String> getCacheNames()

Description copied from interface: CacheManager

Return a collection of the caches known by this cache manager.

Specified by:

getCacheNames in interface CacheManager

Returns:

names of caches known by the cache manager.

getCache

public Cache getCache(java.lang.String name)

Description copied from interface: CacheManager

Return the cache associated with the given name.

Specified by:

getCache in interface CacheManager

Parameters:

name - cache identifier (must not be null)

Returns:

associated cache, or null if none is found

createConcurrentMapCache

protected Cache createConcurrentMapCache(java.lang.String name)

Create a new ConcurrentMapCache instance for the specified cache name.

Parameters:

name - the name of the cache

Returns:

the ConcurrentMapCache (or a decorator thereof)
