Specified by:

getWorkingSolution in interface SolutionDirector

Returns:

never null

resetCalculateCount

public void resetCalculateCount()

getWorkingFacts

public Collection<Object> getWorkingFacts()

getWorkingPlanningEntityList

public List<Object> getWorkingPlanningEntityList()

isWorkingSolutionInitialized

public boolean isWorkingSolutionInitialized()

calculateScoreFromWorkingMemory

public Score calculateScoreFromWorkingMemory()

Description copied from interface: SolutionDirector

Calculates the and updates the workingSolution accordingly.

Specified by:

calculateScoreFromWorkingMemory in interface SolutionDirector

Returns:

never null, the score of the working solution

dispose

public void dispose()

assertWorkingScore

public void assertWorkingScore(Score presumedScore)

Parameters:

presumedScore - never null
