@NullMarked
public final class ForEachFromSolutionUniNode<Solution_,A>
extends ForEachIncludingUnassignedUniNode<A>
implements AbstractForEachUniNode.InitializableForEachNode<Solution_>

Node that reads a property from a planning solution. Since anything directly on a solution is only allowed to change with a new working solution, this node has the following properties:

• Requires initialization when setting new working solution. Inserts at any other time are not allowed.
• Does not allow retracts. Items can not be removed.
• Updates should still be possible, since the values may be planning entities.

Method Details

initialize

public void initialize(Solution_ workingSolution,
 SupplyManager supplyManager)

Specified by:

initialize in interface AbstractForEachUniNode.InitializableForEachNode<Solution_>

insert

public void insert(A a)

Overrides:

insert in class AbstractForEachUniNode<A>

retract

public void retract(A a)

Overrides:

retract in class AbstractForEachUniNode<A>

supports

public boolean supports(AbstractForEachUniNode.LifecycleOperation lifecycleOperation)

Description copied from class: AbstractForEachUniNode

Determines if this node supports the given lifecycle operation. Unsupported nodes will not be called during that lifecycle operation.

Overrides:

supports in class ForEachIncludingUnassignedUniNode<A>

Parameters:

lifecycleOperation - the lifecycle operation to check

Returns:

true if the given lifecycle operation is supported; otherwise, false.

close

public void close()

Specified by:

close in interface AbstractForEachUniNode.InitializableForEachNode<Solution_>

Specified by:

close in interface AutoCloseable
