public class SingletonCacheFactoryBuilder
extends ScopedCacheFactoryBuilder

Implementation of CacheFactoryBuilder that maintains a single ConfigurableCacheFactory instance regardless of the requesting ClassLoader if a URI is not provided. This builder preserves behavior prior to Coherence 3.5.1.

As of Coherence 3.7, this implementation no longer provides various "validation strategies". The SingletonCacheFactoryBuilder is functionally equivalent to the pre 3.7 "compatibility" mode. For more advanced usage it is recommended to configure the ScopedCacheFactoryBuilder or, in rare cases, configure a custom ScopedCacheFactoryBuilder extension.

Since:

Coherence 3.5.1

SingletonCacheFactoryBuilder

public SingletonCacheFactoryBuilder()

Method Details

getSingletonFactory

protected ConfigurableCacheFactory getSingletonFactory()

Return the singleton cache factory. A singleton cache factory is an unnamed configurable cache factory that does not depend on a class loader.

Returns:

the singleton cache factory

setSingletonFactory

protected void setSingletonFactory(ConfigurableCacheFactory ccf)

Set the singleton cache factory (see getSingletonFactory()).

Parameters:

ccf - the singleton configurable cache factory

setCacheConfiguration

public void setCacheConfiguration(String sConfigURI,
 ClassLoader loader,
 XmlElement xmlConfig)

Dynamically set the cache configuration for a given URI and class loader. If a ConfigurableCacheFactory for the given URI and class loader already exists, the factory will be released.

Specified by:

setCacheConfiguration in interface CacheFactoryBuilder

Overrides:

setCacheConfiguration in class ScopedCacheFactoryBuilder

Parameters:

sConfigURI - the configuration URI; must not be null

loader - class loader for which the configuration should be used; must not be null

xmlConfig - cache configuration in xml element format

releaseAll

public void releaseAll(ClassLoader loader)

Release all ConfigurableCacheFactory objects for a given ClassLoader.

Specified by:

releaseAll in interface CacheFactoryBuilder

Overrides:

releaseAll in class ScopedCacheFactoryBuilder

Parameters:

loader - the class loader for which all associated cache factories should be released

release

public void release(ConfigurableCacheFactory factory)

Release the specified ConfigurableCacheFactory.

Specified by:

release in interface CacheFactoryBuilder

Overrides:

release in class ScopedCacheFactoryBuilder

Parameters:

factory - the ConfigurableCacheFactory to release

getFactory

protected ConfigurableCacheFactory getFactory(String sConfigURI,
 ClassLoader loader,
 ParameterResolver resolver)

Helper method to return a ConfigurableCacheFactory instance for the specified URI and class loader.

Overrides:

getFactory in class ScopedCacheFactoryBuilder

Parameters:

sConfigURI - the configuration URI to return a ConfigurableCacheFactory for

loader - the loader to return a CCF for

Returns:

a ConfigurableCacheFactory instance
