evaluate

public Object evaluate(Object feature)
Description copied from class: DefaultExpression
This method checks if the object is an instance of Feature and if so, calls through to #evaluate(Feature). This is done to maintain backwards compatability with previous version of Expression api which depended on Feature. If the object is not an instance of feature the super implementation is called.

Specified by:
evaluate in interface Expression
Overrides:
evaluate in class DefaultExpression
