Class DecisionExecutionPath

java.lang.Object

com.openrules.ruleengine.DecisionExecutionPath

public class DecisionExecutionPath
extends java.lang.Object

This class defines an execution path that can be automatically build for decision models with one or more goals, for which the method "Decision"is not specified in Excel. The execution path can execute the goal for which it was defined. It can save itself in an Excel files along with the definitions of all goals.

Constructor Detail

DecisionExecutionPath

public DecisionExecutionPath(Decision decision)

This is a constructor that creates an instance of DecisionExecutionPath for any decision passed as a parameter. It automatically determines dependencies between all decision variables and their modifiers. It uses the following algorithm: 1) for each decision table extract all decision variables 2) create a list of all "output" decision variables that are found in the actions 3) for each output variable find other output variables which this one requires - they can be found in the condition titles of its decision tables - inside rule cells for input and output columns You still need to call defineGoal(Goal goal) method to calculate an execution path for a particular goal.

Parameters:

decision -

Method Detail

getExecutionPath

public java.util.ArrayList<java.lang.String> getExecutionPath()

setExecutionPath

public void setExecutionPath(java.util.ArrayList<java.lang.String> executionPath)

define

public boolean define(java.lang.String goal)

Builds an internal list of decision table names that will be used to execute the "goal" by recursively adding all subgoals in the correct order.

Parameters:

goal - a String

Returns:

true if everything is OK or false if the "goal" cannot be found among decision variables.
