Class DiscriminableDiscriminator<T>

java.lang.Object
  net.sf.jagg.msd.AbstractDiscriminator<T>
      net.sf.jagg.msd.DiscriminableDiscriminator<T>

All Implemented Interfaces:

Discriminator<T>

public class DiscriminableDiscriminator<T>
extends AbstractDiscriminator<T>

A DiscriminableDiscriminator assumes that the type of elements is Discriminable. It extracts the properties, then delegates to a PropertiesDiscriminator.

Since:

0.5.0

<E> java.util.List<java.util.List<E>>

discriminate(java.util.List<E> elements, Extractor<E,T> extractor, MsdWorkspace workspace) Partitions the given List of elements into another List, in which all of the elements from the given list exist in the new list, and all elements that compare equal are adjacent to each other, according to the given Extractor.

Method Detail

discriminate

public <E> java.util.List<java.util.List<E>> discriminate(java.util.List<E> elements,
                                                          Extractor<E,T> extractor,
                                                          MsdWorkspace workspace)

Partitions the given List of elements into another List, in which all of the elements from the given list exist in the new list, and all elements that compare equal are adjacent to each other, according to the given Extractor.

Type Parameters:

E - The type of element that is being discriminated by the type <E>

Parameters:

elements - A List of elements.

extractor - An Extractor that gives labels for each element.

workspace - The MsdWorkspace used in the discrimination process.

Returns:

A List of Lists containing all equivalence classes. Each equivalence class list contains all elements that compare equal to each other.

Throws:

java.lang.ClassCastException - If an encountered object was not Discriminable.
