Class ResultImpl

java.lang.Object
  net.sf.javailp.ResultImpl

All Implemented Interfaces:

Result

public class ResultImpl
extends Object
implements Result

The class ResultImpl is a Map based implementation of the Result.

Constructor Summary

ResultImpl()
Constructs a ResultImpl for a Problem without objective function.

ResultImpl(Linear objectiveFunction)
Constructs a ResultImpl for a Problem with an objective function.

ResultImpl(Number objectiveValue)
Constructs a ResultImpl for a Problem with objective function and the optimal value.

Method Summary

Boolean	containsVar(Object var) Returns true if the result contains the variable.
Number	get(Object key) Returns the primal value of the variable.
boolean	getBoolean(Object key) Returns the primal value for a specific var as a boolean.
Number	getDualValue(Object key) Returns the dual value of the variable.
Number	getObjective() Returns the objective value.
Number	getPrimalValue(Object key) Returns the primal value of the variable.
void	put(Object key, Number value) Sets the primal value of the variable.
void	putDualValue(Object key, Number value) Sets the dual value of the variable.
void	putPrimalValue(Object key, Number value) Sets the primal value of the variable.
String	toString()
