Class DefaultVariablesManager

java.lang.Object

com.massa.mrules.addon.DefaultVariablesManager

All Implemented Interfaces:

IAddonsManager

public class DefaultVariablesManager
extends Object
implements IAddonsManager

Declares system variables provided by default. Complete list is :

• DATE: Current date.
• DATETIME: Current date + time.
• TIME: Current time (as Java Runtime before 1.8 does not integrate time representation, a standard Date is used, with date components reset to the "zero epoch").
• NOW: Alias for datetime.
• RULESETNAME: Rule set name.
• READBASE: Force access to context read base.
• WRITEBASE: Force access to context write base.
• ROOTREADBASE: Force access to root context read base.
• ROOTWRITEBASE: Force access to root context write base.

Global variables are handled like standard Addons, of IAccessor type.
