Class CacheFilterPackageImpl

java.lang.Object
  org.apache.ojb.broker.cache.CacheFilterPackageImpl

All Implemented Interfaces:

CacheFilter

public class CacheFilterPackageImpl

extends java.lang.Object

implements CacheFilter

A CacheFilter implementation for filtering objects before cached when the given objects package name match a given package, defined as custom attribute within the descriptor-repository element or jdbc-connection-descriptor in the repository file.
Example:
Add this custom attribute to a jdbc-connection-descriptor to avoid caching of package trees for the described connection.

 <attribute
    attribute-name="exclude-packages"
    attribute-value="org.my.test,org.my.admin"/>
 

To enable a global exclude of caching, add the custom attribute entry under the descriptor-repository element.
