  org.drools.util.asm.ClassFieldInspector

public class ClassFieldInspector
extends Object

Visit a POJO user class, and extract the property getter methods that are public, in the order in which they are declared actually in the class itself (not using introspection). This may be enhanced in the future to allow annotations or perhaps external meta data configure the order of the indexes, as this may provide fine tuning options in special cases.
