/** 
 * An object that can be described in a declarative caching XML file.
 *
 * 

* * Any user-defined object in the declarative caching xml file * should implement this interface in order to be constructed. * *

* * For example, the user can declare a CacheLoader in a declarative * XML file as follows: * *

 *        <cache-loader>
 *          <class-name>com.company.app.DBLoader</class-name>
 *          <parameter name="URL">
 *            <string>jdbc://12.34.56.78/mydb</string>
 *          </parameter>
 *        </cache-loader>
 * 
* *

* * In this case, com.company.app.DBLoader must * implement both the {@link CacheLoader} and Declarable * interfaces. The cache service will construct a * com.company.app.DBLoader object by invoking the loader's * zero-argument constructor and then calling the {@link #init} method * to pass in the parameters. * *

* * See package introduction. * * @author Darrel Schneider * * * @since 2.0 */ public interface Declarable { /** * Initializes a user-defined object using the given properties. * Note that any uncaught exception thrown by this method will cause * the Cache initialization to fail. * * @param props * Contains the parameters declared in the declarative xml * file. * * @throws IllegalArgumentException * If one of the configuration options in props * is illegal or malformed. */ public void init(Properties props); }
