Interface ConstraintPlacementAlgorithm

All Known Implementing Classes:
DefaultPlacementAlgorithm
public interface ConstraintPlacementAlgorithm
Marker interface for a Constraint Placement. The only contract is that it should be initialized with the RMContext.

  • Method Details

    • init

      void init(RMContext rmContext)
      Initialize the Algorithm.
      Parameters:
      rmContext - RMContext.

    • place

      void place(ConstraintPlacementAlgorithmInput algorithmInput, ConstraintPlacementAlgorithmOutputCollector collector)
      The Algorithm is expected to compute the placement of the provided ConstraintPlacementAlgorithmInput and use the collector to aggregate any output.
      Parameters:
      algorithmInput - Input to the Algorithm.
      collector - Collector for output of algorithm.
