Class ChoiceList

java.lang.Object
oracle.rules.sdk2.dictionary.ChoiceList

public class ChoiceList

extends java.lang.Object

A ChoiceList provides a hierarchy to the flat array of Strings returned from the SDK2 getOptions methods.

We use String[] for 3 different purposes:

1. pass the flat options from the SDK to the ChoiceList constructor
2. return the options for each level in the hierarchy (return of getNextChoices)
3. to represent a partial or complete selection from first level to N levels (previousSelections) (List<String&rt; is also provided for convenience)
