Method Detail

executeAfterConsistency

public boolean executeAfterConsistency(boolean consistent)

Description copied from interface: ConsistencyListener

It is executed right after consistency of the current search node. Returning true when the parameter was false is not advised as things like invalid solutions can be found.

Specified by:

executeAfterConsistency in interface ConsistencyListener

Parameters:

consistent - specifies if the consistency call returned true or false.

Returns:

true if the search should continue, false if the search should act as the consistency returned false.

setChildrenListeners

public void setChildrenListeners(ConsistencyListener[] children)

Description copied from interface: ConsistencyListener

Each of the child listeners will be called and the return code from them will be combined (taken into account) by a parent).

Specified by:

setChildrenListeners in interface ConsistencyListener

Parameters:

children - the children listeners attached to this listener.

setChildrenListeners

public void setChildrenListeners(ConsistencyListener child)

Description copied from interface: ConsistencyListener

Setting one child listener.

Specified by:

setChildrenListeners in interface ConsistencyListener

Parameters:

child - the only child listener added to this consistency listener.

collectFailStatistics

void collectFailStatistics(Constraint currentConstraint)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

sortByValues

private static java.util.List<java.util.Map.Entry<java.lang.String,java.lang.Integer>> sortByValues(java.util.Map<java.lang.String,java.lang.Integer> map)
