org.thechiselgroup.choosel.core.client.visualization.model.VisualItemValueResolver

Calculates a value given a {@link VisualItem}. Implementations of this interface must be immutable.

{@code VisualItemValueResolver}s can use other {@code VisualItemValueResolver}s defined on other {@link Slot}s of this {@link VisualizationModel} in theircalculation. The {@link VisualItemValueResolverContext} exposes those duringthe calculation. However, they must declare the {@link Slot}s they depend on in {@link #getTargetSlots()}.
