Examples of IRObject

com.dtrules.interpreter.IRObject
Every Rules Engine object implements the IRObject interface. This interface is used by the Interpreter to execute objects, and by the implementation of operators to manipulate objects.

This interface implements the necessary methods for doing the data conversions necessary when extracting data from the Rules Engine state after having executed a set of rules. @author Paul Snow
