de.lmu.ifi.dbs.elki.visualization.projections.AbstractFullProjection

All Implemented Interfaces:

FullProjection, Projection, VisualizationItem

Direct Known Subclasses:

AbstractSimpleProjection, AffineProjection

public abstract class AbstractFullProjection
extends AbstractProjection
implements FullProjection

Abstract base class for full projections. Note: the full projection API may be removed at some point, unless we find a clear use case that cannot be done by the low level fast projections.
