Interface JCacheOperationSource

All Known Implementing Classes:

AbstractFallbackJCacheOperationSource, AnnotationJCacheOperationSource, DefaultJCacheOperationSource

public interface JCacheOperationSource

Interface used by JCacheInterceptor. Implementations know how to source cache operation attributes from standard JSR-107 annotations.

Method Summary

Modifier and Type	Method	Description
@Nullable JCacheOperation<?>	getCacheOperation(Method method, @Nullable Class<?> targetClass)	Return the cache operations for this method, or null if the method contains no JSR-107 related metadata.
default boolean	hasCacheOperation(Method method, @Nullable Class<?> targetClass)	Determine whether there is a JSR-107 cache operation for the given method.
default boolean	isCandidateClass(Class<?> targetClass)	Determine whether the given class is a candidate for cache operations in the metadata format of this JCacheOperationSource.

Method Details

isCandidateClass

default boolean isCandidateClass(Class<?> targetClass)

Determine whether the given class is a candidate for cache operations in the metadata format of this JCacheOperationSource.

If this method returns false, the methods on the given class will not get traversed for getCacheOperation(Method, 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.

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.

6.2

hasCacheOperation

default boolean hasCacheOperation(Method method,
 @Nullable Class<?> targetClass)

Determine whether there is a JSR-107 cache operation for the given method.

Parameters:

method - the method to introspect

targetClass - the target class (can be null, in which case the declaring class of the method must be used)

getCacheOperation

@Nullable JCacheOperation<?> getCacheOperation(Method method,
 @Nullable Class<?> targetClass)

Return the cache operations for this method, or null if the method contains no JSR-107 related metadata.

Parameters:

method - the method to introspect

targetClass - the target class (can be null, in which case the declaring class of the method must be used)

Returns:

the cache operation for this method, or null if none found
