Annotation Type CacheRemoveAll

@Target(value={METHOD,TYPE})
 @Retention(value=RUNTIME)
public @interface CacheRemoveAll

When a method annotated with CacheRemoveAll is invoked all elements in the specified cache will be removed via the Cache.removeAll() method

The default behavior is to call Cache.removeAll() after the annotated method is invoked, this behavior can be changed by setting afterInvocation() to false in which case Cache.removeAll() will be called before the annotated method is invoked.

Example of removing all Domain objects from the "domainCache". Cache.removeAll() will be called after deleteAllDomains() returns successfully.

 package my.app;
 
 public class DomainDao {
   @CacheRemoveAll(cacheName="domainCache")
   public void deleteAllDomains() {
     ...
   }
 }
 

Exception Handling, only used if afterInvocation() is true.

1. If evictFor() and noEvictFor() are both empty then all exceptions prevent the removeAll
2. If evictFor() is specified and noEvictFor() is not specified then only exceptions that pass an instanceof check against the evictFor list result in a removeAll
3. If noEvictFor() is specified and evictFor() is not specified then all exceptions that do not pass an instanceof check against the noEvictFor result in a removeAll
4. If evictFor() and noEvictFor() are both specified then exceptions that pass an instanceof check against the evictFor list but do not pass an instanceof check against the noEvictFor list result in a removeAll

Optional Elements

Modifier and Type	Optional Element and Description
boolean	afterInvocation When Cache.removeAll() should be called.
String	cacheName /** The name of the cache.
Class<? extends CacheResolverFactory>	cacheResolverFactory The CacheResolverFactory used to find the CacheResolver to use at runtime.
Class<? extends Throwable>[]	evictFor Defines zero (0) or more exception classes, that must be a subclass of Throwable, indicating the exception types that must cause a cache eviction.
Class<? extends Throwable>[]	noEvictFor Defines zero (0) or more exception Classes, that must be a subclass of Throwable, indicating the exception types that must not cause a cache eviction.

Element Detail

cacheName

public abstract String cacheName

/** The name of the cache.

If not specified defaults first to CacheDefaults.cacheName() and if that is not set it defaults to: package.name.ClassName.methodName(package.ParameterType,package.ParameterType)

Default:

""

afterInvocation

public abstract boolean afterInvocation

When Cache.removeAll() should be called. If true it is called after the annotated method invocation completes successfully. If false it is called before the annotated method is invoked.

Defaults to true.

If true and the annotated method throws an exception the removeAll will not be executed.

Default:

true

cacheResolverFactory

public abstract Class<? extends CacheResolverFactory> cacheResolverFactory

The CacheResolverFactory used to find the CacheResolver to use at runtime.

The default resolver pair will resolve the cache by name from the default CacheManager

Default:

javax.cache.annotation.CacheResolverFactory.class

evictFor

public abstract Class<? extends Throwable>[] evictFor

Defines zero (0) or more exception classes, that must be a subclass of Throwable, indicating the exception types that must cause a cache eviction. Only used if afterInvocation() is true.

Default:

{}

noEvictFor

public abstract Class<? extends Throwable>[] noEvictFor

Defines zero (0) or more exception Classes, that must be a subclass of Throwable, indicating the exception types that must not cause a cache eviction. Only used if afterInvocation() is true.

Default:

{}
