Package javax.cache.annotation

Annotation Type CachePut

@Target({METHOD,TYPE})
@Retention(RUNTIME)
public @interface CachePut

When a method annotated with CachePut is invoked a GeneratedCacheKey will be generated and Cache.put(Object, Object) will be invoked on the specified cache storing the value marked with CacheValue.

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

Example of caching the Domain object with a key generated from the String and int parameters. The CacheValue annotation is used to designate which parameter should be stored in the "domainDao" cache.

 package my.app;
 
 public class DomainDao {
   @CachePut(cacheName="domainCache")
   public void updateDomain(String domainId, int index, @CacheValue Domain
 domain) {
     ...
   }
 }
 

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

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

Optional Element Summary

Optional Elements

Modifier and Type	Optional Element	Description
boolean	afterInvocation	When Cache.put(Object, Object) should be called.
java.lang.Class<? extends java.lang.Throwable>[]	cacheFor	Defines zero (0) or more exception classes, that must be a subclass of Throwable, indicating the exception types that must cause the parameter to be cached.
java.lang.Class<? extends CacheKeyGenerator>	cacheKeyGenerator	The CacheKeyGenerator to use to generate the GeneratedCacheKey for interacting with the specified Cache.
java.lang.String	cacheName	The name of the cache.
java.lang.Class<? extends CacheResolverFactory>	cacheResolverFactory	The CacheResolverFactory used to find the CacheResolver to use at runtime.
java.lang.Class<? extends java.lang.Throwable>[]	noCacheFor	Defines zero (0) or more exception Classes, which must be a subclass of Throwable, indicating which exception types must not cause the parameter to be cached.

Element Detail

cacheName

java.lang.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

boolean afterInvocation

When Cache.put(Object, Object) 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 rules governing cacheFor() and noCacheFor() will be followed.

Default:

true

cacheResolverFactory

java.lang.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

cacheKeyGenerator

java.lang.Class<? extends CacheKeyGenerator> cacheKeyGenerator

The CacheKeyGenerator to use to generate the GeneratedCacheKey for interacting with the specified Cache.

Defaults to a key generator that uses Arrays.deepHashCode(Object[]) and Arrays.deepEquals(Object[], Object[]) with the array returned by CacheKeyInvocationContext.getKeyParameters()

See Also:

CacheKey

Default:

javax.cache.annotation.CacheKeyGenerator.class

cacheFor

java.lang.Class<? extends java.lang.Throwable>[] cacheFor

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

Default:

{}

noCacheFor

java.lang.Class<? extends java.lang.Throwable>[] noCacheFor

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

Default:

{}
