Method Detail

getCacheName

public static String getCacheName(Method method,
                                  String methodCacheName,
                                  javax.cache.annotation.CacheDefaults cacheDefaultsAnnotation,
                                  boolean generate)

Resolves the cache name of a method annotated with a JCACHE annotation.

Parameters:

method - the annotated method.

methodCacheName - the cache name defined on the JCACHE annotation.

cacheDefaultsAnnotation - the CacheDefaults annotation instance.

generate - true if the default cache name has to be returned if none is specified.

Returns:

the resolved cache name.

Throws:

NullPointerException - if method or methodCacheName parameter is null.

getCacheKeyGenerator

public static javax.cache.annotation.CacheKeyGenerator getCacheKeyGenerator(javax.enterprise.inject.spi.BeanManager beanManager,
                                                                            Class<? extends javax.cache.annotation.CacheKeyGenerator> methodCacheKeyGeneratorClass,
                                                                            javax.cache.annotation.CacheDefaults cacheDefaultsAnnotation)

Resolves and creates an instance of CacheKeyGenerator. To resolve the cache key generator class the algorithm defined in JCACHE specification is used.

Parameters:

beanManager - the bean manager instance.

methodCacheKeyGeneratorClass - the CacheKeyGenerator class declared in the cache annotation.

cacheDefaultsAnnotation - the CacheDefaults annotation instance.

Returns:

the CacheKeyGenerator instance.

Throws:

NullPointerException - if beanManager parameter is null.
