All Implemented Interfaces:

INamedThing, IMethodFactory, IOpenLibrary, IVarFactory, IType, IMetaHolder, IOpenClass

public class DecisionTableDataType
extends ComponentOpenClass

Provides access to the elements of the Decision table as data.

Each Condition and action becomes an internal type and parameters become attributes of this type.

Current implementation has the following limitations:

a) it supports only the access from action method to the variables defined in conditions. No access to other actions is provided b) it will work only if variables in conditions are constants (not formulas) c) it does not provide access to other rules than current one (for example we may want to access the previous rule via $previous.$C1.limit or any random rule via $rules[7].$C1.limit etc.) d) the data is accessible only from inside of the DecisionTable, there is no access from the outside, this will require a special meta-facility in the project to provide standardized external access to internals of the different tables
