Class AbstractFallbackJCacheOperationSource

java.lang.Object

org.springframework.cache.jcache.interceptor.AbstractFallbackJCacheOperationSource

All Implemented Interfaces:

JCacheOperationSource

Direct Known Subclasses:

AnnotationJCacheOperationSource

public abstract class AbstractFallbackJCacheOperationSource
extends java.lang.Object
implements JCacheOperationSource

Abstract implementation of JCacheOperationSource that caches attributes for methods and implements a fallback policy: 1. specific target method; 2. declaring method.

This implementation caches attributes by method after they are first used.

Since:

4.1

Method Detail

getCacheOperation

public JCacheOperation<?> getCacheOperation(java.lang.reflect.Method method,
                                            java.lang.Class<?> targetClass)

Description copied from interface: JCacheOperationSource

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

Specified by:

getCacheOperation in interface JCacheOperationSource

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:

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

computeCacheOperation

private JCacheOperation<?> computeCacheOperation(java.lang.reflect.Method method,
                                                 java.lang.Class<?> targetClass)

findCacheOperation

protected abstract JCacheOperation<?> findCacheOperation(java.lang.reflect.Method method,
                                                         java.lang.Class<?> targetType)

Subclasses need to implement this to return the caching operation for the given method, if any.

Parameters:

method - the method to retrieve the operation for

targetType - the target class

Returns:

the cache operation associated with this method (or null if none)

allowPublicMethodsOnly

protected boolean allowPublicMethodsOnly()

Should only public methods be allowed to have caching semantics?

The default implementation returns false.
