Class ISMgr

java.lang.Object

org.springsource.loaded.ISMgr

public class ISMgr
extends java.lang.Object

Every reloadable hierarchy gets an Instance State Manager (ISMgr). The instance state manager is used to find the value of a field for a particular object instance. The manager is added to the top most type in a reloadable hierarchy and is accessible to all the subtypes. It maintains a map from types to secondary maps. The secondary maps record name,value pairs for each field. The maps are only used if something has happened to mean we cannot continue to store the values in the original fields.

Since:
