Examples of com.dtrules.interpreter.IRObject.stringValue()

com.dtrules.interpreter.IRObject.stringValue()
By default, the toString() method for most Objects should provide a representation of the object that can be used as the postFix value. The stringValue should provide simply the data for the object. Thus If I want to append the a String and a Date to create a new string, I should append the results from their stringValue() implementation.

If I needed the postfix (and thus the quotes and maybe other ) then call postFix(). But if the postFix is going to match either stringValue() or toString, it is going to match toString().
