org.imixs.workflow.engine.plugins.HistoryPlugin

All Implemented Interfaces:

Plugin

public class HistoryPlugin
extends AbstractPlugin

This Plugin creates a history log in the property txtWorkflowHistory. The history log contains a list of history entires. Each entry provides the following information:

• date of creation (Date)
• comment (String)
• userID (String)

Note: In early versions of this plugin the history entries were stored in a simple string list. The date was separated by the char sequence ' : ' from the comment entry. The userId was not stored explicit. This plugin converts the old format automatically (see method convertOldFormat)
