Method Detail

nextAttribute

Attribute nextAttribute(java.util.Map<java.lang.String,java.lang.String> chosenAttributes,
                        java.util.Set<java.lang.String> usedAttributes)

Find the next attribute. For the initial attribute, pass an empty chosenAttributes and use the returned attribute as the rootAttribute. Then, walk the decision tree pre-order. At each decision, call this method with the attribute/decision pairs that led to that node in chosenAttributes. Attach the returned Attribute to the decision.
