java.lang.Object

com.ibm.commerce.context.content.resources.dynacache.DynaCacheUtility

public class DynaCacheUtility
extends java.lang.Object

DynaCacheUtility is a utility class for generating WebSphere Dynamic Cache invalidation IDs. It loads all the cache invalidation ID generators registered in the cache invalidation configuration file, and invokes them to generate invalidation IDs.

Method Summary

Modifier and Type	Method and Description
java.util.List	generateInvalidationIDs(java.lang.String resource, java.lang.String[] resourceKeys, java.util.HashMap oneRecord, java.lang.String action, java.sql.Connection connection, java.lang.String schema) invokes all the registered CacheInvalidationIDGenerator instances to generate WebSphere Dynamic Cache invalidation IDs.
void	initialize(java.net.URL configURL) initializes the instance by reading the cache invalidation configuration.
boolean	isInvalidationTrigger(java.lang.String resource, java.lang.String action) returns whether performing the action against the resource would trigger cache invalidation.
static DynaCacheUtility	singleton() returns the singleton of the DynaCacheUtility.

Parameters:

resource - the resource.

resourceKeys - the resource keys.

oneRecord - a HashMap object contains the values in the resource object.

action - the action performed against the resource object.

connection - the database connection.

schema - the database schema name.
