Examples of com.dtrules.interpreter.RArray

com.dtrules.interpreter.RArray
Immplements Arrays for Decision Tables. Because we can't tag references, we do the same trick here that we do for RNames, i.e. we create an executable and a non-executable version of each array. However, we only create one ArrayList.

If dups is true, we allow duplicate references in the array. Sometimes it is pleasent to have an array whose values are all unique. In that case, create an array with dups set to false.
