Modifier and Type	Method	Description
`Collection<CacheOperation>`	`getCacheOperations(Method method, Class<?> targetClass)`	Return the collection of cache operations for this method, or `null` if the method contains no cacheable annotations.
`CacheOperationSource[]`	`getCacheOperationSources()`	Return the `CacheOperationSource` instances that this `CompositeCacheOperationSource` combines.
`boolean`	`isCandidateClass(Class<?> targetClass)`	Determine whether the given class is a candidate for cache operations in the metadata format of this `CacheOperationSource`.

public CompositeCacheOperationSource(CacheOperationSource... cacheOperationSources)

    Create a new CompositeCacheOperationSource for the given sources.
    Parameters:
    cacheOperationSources - the CacheOperationSource instances to combine

```
    Description copied from interface: CacheOperationSource
    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.
    Specified by:
    isCandidateClass in interface CacheOperationSource
    Parameters:
    targetClass - the class to introspect
    Returns:
    false if the class is known to have no cache operation metadata at class or method level; true otherwise. The default implementation returns true, leading to regular introspection.

    Description copied from interface: CacheOperationSource
    Return the collection of cache operations for this method, or null if the method contains no cacheable annotations.
    Specified by:
    getCacheOperations in interface CacheOperationSource
    Parameters:
    method - the method to introspect
    targetClass - the target class (may be null, in which case the declaring class of the method must be used)
    Returns:
    all cache operations for this method, or null if none found
