Annotation Elements

Table 2-7 describes this annotation's elements.

Table 2-7 @CacheInterceptor Annotation Elements

Annotation Element Description Default

value

The class to be used to intercept EclipseLink's cache access.




Usage

Once set, the specified class will receive all caching calls. Existing EclipseLink cache settings will continue to be used, any calls allowed to continue to the EclipseLink cache will execute against the configured cache.

When using with an entity in inheritance, you should define the @CacheInterceptor on the root of the inheritance hierarchy.


Examples

Example 2-16 shows how to integrate an external cache with EclipseLink.

Example 2-16 Using @CacheInterceptor Annotation

In this example, the Employee class intercepts all EclipseLink calls to the internal EclipseLink cache and redirects them to the Oracle Coherence Grid cache (CoherenceInterceptor).

import oracle.eclipselink.coherence.integrated.cache.CoherenceInterceptor;
import org.eclipse.persistence.annotations.Customizer;
 
@Entity
@CacheInterceptor(value = CoherenceInterceptor.class)
public class Employee {
...
}

Example 2-17 shows an example of using the <cache-interceptor> XML element in the eclipselink-orm.xml file.

Example 2-17 Using <cache-interceptor> XML

<entity class="Employee">
    <cache-interceptor class="CoherenceInterceptor"/>
...
</entity>
