Interface WorkUnitWeighter

public interface WorkUnitWeighter

Provides weights for WorkUnits to use by a WorkUnitBinPacker.

The weight is used by a bin packing algorithm to organize WorkUnits into MultiWorkUnits with a bounded total weight. The weighter must have the following properties:

• If wu1.equals(wu2), then weight(wu1) == weight(wu2).
• Each weight must be positive.

Ideally, the weights are a linear representation of the resources needed to process a work unit.
