Local

While configuring the rule engine, it might be useful to integrate variables. For example, to perform a count, to store current index in a loop, etc…

4 Addons allow to define a variable:

• DEF: Dedicated to this purpose.
• FOREACH: 2 variables might be defined: current item an index.
• FOREACHNUMBER: 2 variables might be defined: current item an index.
• EXEC: Exit code is stored in a variable.

These Addons are given the variable name as a parameter. It may be accessed later by prefixing this name with the « $ » character.

Global

In addition to local variables, globales ones are natively available for all exécutions. They must be prefixed by the « # » character to be accessed. Here is the list:

• 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.
• NULL: The Java “null” value.
• RULESETNAME: Rule set name.
• READBASE: Forces access to current context write base.
• WRITEBASE: Forces access to current context read base.
• ROOTREADBASE: Forces access to root context read base. This is useful when using sub-properties (in collection filtering for instance). If current context is the root context, then ROOTREADBASE is equivalent to READBASE.
• ROOTWRITEBASE: Forces access to root context write base. This is useful when using sub-properties (in collection filtering for instance). If current context is the root context, then ROOTWRITEBASE is equivalent to WRITEBASE.
