Class LDAPGroupCache

java.lang.Object

org.activiti.ldap.LDAPGroupCache

public class LDAPGroupCache
extends Object

Simple cache for groups a user belongs to, which avoid hitting the LDAP system too much. Groups are fetched internally by the engine for exampe when doing queries, eg when fetching tasks for a candidateUser. Configured through the LDAPConfigurator. Cached entries have an expiration time. For example when set to one hour, changes to the ldap system around the groups of a user will be visible after that hour. Experimental: can have a listener for cache events, and instance of LDAPGroupCache.LDAPGroupCacheListener.
