Class FutureSolution

java.lang.Object
  org.moeaframework.core.Solution
      org.moeaframework.util.distributed.FutureSolution

All Implemented Interfaces:

Serializable

public class FutureSolution
extends Solution

Represents a Solution evaluated asynchronously. Calls to

• getObjective(int)
• getObjectives()
• getConstraint(int)
• getConstraints()

will block until the asynchronous evaluation completes. This behavior is achieved by assigning a Future through the setFuture(Future) method prior to submitting this solution for evaluation.

Method Detail

copy

public FutureSolution copy()

Description copied from class: Solution

Returns an independent copy of this solution. It is required that x.copy() is completely independent from x . This means any method invoked on x.copy() in no way alters the state of x and vice versa. It is typically the case that x.copy().getClass() == x.getClass() and x.copy().equals(x)

Note that a solution's attributes are not copied, as the attributes are generally specific to each instance.

Overrides:

copy in class Solution

Returns:

an independent copy of this solution

getObjectives

public double[] getObjectives()

Description copied from class: Solution

Returns an array containing the objectives of this solution. Modifying the returned array will not modify the internal state of this solution.

Overrides:

getObjectives in class Solution

Returns:

an array containing the objectives of this solution

getConstraint

public double getConstraint(int index)

Description copied from class: Solution

Returns the constraint at the specified index.

Overrides:

getConstraint in class Solution

Parameters:

index - index of the variable to be returned

Returns:

the constraint at the specified index

getConstraints

public double[] getConstraints()

Description copied from class: Solution

Returns an array containing the constraints of this solution. Modifying the returned array will not modify the internal state of this solution.

Overrides:

getConstraints in class Solution

Returns:

an array containing the constraints of this solution

getObjective

public double getObjective(int index)

Description copied from class: Solution

Returns the objective at the specified index.

Overrides:

getObjective in class Solution

Parameters:

index - index of the objective to return

Returns:

the objective at the specified index
