public class CompositeCacheOperationSource extends Object implements CacheOperationSource, Serializable
CacheOperationSource implementation that iterates
 over a given array of CacheOperationSource instances.| Constructor and Description |

| CompositeCacheOperationSource(CacheOperationSource... cacheOperationSources)Create a new CompositeCacheOperationSource for the given sources. | 
| Modifier and Type | Method and Description | 
|---|---|
| Collection<CacheOperation> | getCacheOperations(Method method,
                  Class<?> targetClass)Return the collection of cache operations for this method,
 or  nullif the method contains no cacheable annotations. | 
| CacheOperationSource[] | getCacheOperationSources()Return the  CacheOperationSourceinstances that thisCompositeCacheOperationSourcecombines. | 
| boolean | isCandidateClass(Class<?> targetClass)Determine whether the given class is a candidate for cache operations
 in the metadata format of this  CacheOperationSource. |

 If this method returns false, the methods on the given class
 will not get traversed for CacheOperationSource.getCacheOperations(java.lang.reflect.Method, java.lang.Class<?>) introspection.
 Returning false is therefore an optimization for non-affected
 classes, whereas true simply means that the class needs to get
 fully introspected for each method on the given class individually.
