Method Detail

getN

public int getN()

setN

public void setN(int n)

getColumnList

public List<Column> getColumnList()

setColumnList

public void setColumnList(List<Column> columnList)

getRowList

public List<Row> getRowList()

setRowList

public void setRowList(List<Row> rowList)

getQueenList

public List<Queen> getQueenList()

getScore

public SimpleScore getScore()

Description copied from interface: Solution

Returns the Score of this Solution.

Specified by:

getScore in interface Solution<SimpleScore>

Returns:

null if the Solution is uninitialized or the last calculated Score is dirty the new Score has not yet been recalculated

setScore

public void setScore(SimpleScore score)

Description copied from interface: Solution

Called by the Solver when the Score of this Solution has been calculated.

Specified by:

setScore in interface Solution<SimpleScore>

Parameters:

score - null if the Solution has changed and the new Score has not yet been recalculated

getProblemFacts

public Collection<? extends Object> getProblemFacts()

Description copied from interface: Solution

Called by the DroolsScoreDirector when the Solution needs to be inserted into an empty WorkingMemory. These facts can be used by the score rules. They don't change during planning (except through ProblemFactChange events).

Do not include the planning entities as problem facts: they are automatically inserted into the WorkingMemory if and only if they are initialized. When they are initialized later, they are also automatically inserted.

Specified by:

getProblemFacts in interface Solution<SimpleScore>

Returns:

never null (although an empty collection is allowed), all the facts of this solution except for the planning entities
