Interface LogicalElement<T>

  • Type Parameters:
    T - the type of element (e.g., a bitmap class)
    All Known Implementing Classes:
    EWAHCompressedBitmap, EWAHCompressedBitmap32
    public interface LogicalElement<T>
    A prototypical model for bitmaps. Used by the class FastAggregation. Users should probably not be concerned by this class.
