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.
