Class RuntimeFacetHandler<D>

java.lang.Object
  com.browseengine.bobo.facets.FacetHandler<D>
      com.browseengine.bobo.facets.RuntimeFacetHandler<D>

Type Parameters:

D - type parameter for FacetData

Direct Known Subclasses:

DynamicRangeFacetHandler, GeoSimpleFacetHandler, HistogramFacetHandler

public abstract class RuntimeFacetHandler<D>
extends FacetHandler<D>

Abstract class for RuntimeFacetHandlers. A concrete RuntimeFacetHandler should implement the FacetHandlerFactory and RuntimeInitializable so that bobo knows how to create new instance of the handler at run time and how to initialize it at run time respectively.
