Class SimpleAdapter

java.lang.Object

de.lmu.ifi.dbs.elki.evaluation.scores.adapter.SimpleAdapter

All Implemented Interfaces:

DBIDRefIter, ScoreEvaluation.ScoreIter, Iter

public class SimpleAdapter
extends Object
implements ScoreEvaluation.ScoreIter, DBIDRefIter

This adapter can be used for an arbitrary collection of Integers, and uses that id1.compareTo(id2) != 0 for id1 != id2 to satisfy the comparability. Note that of course, no id should occur more than once. The ROC values would be incorrect then anyway!

Since:

0.7.0

iter - Iterator for object IDs

Method Detail

valid

public boolean valid()

Description copied from interface: Iter

Returns true if the iterator currently points to a valid object.

Specified by:

valid in interface Iter

Returns:

a boolean value, whether the position is valid.

advance

public SimpleAdapter advance()

Description copied from interface: Iter

Moves the iterator forward to the next entry.

Specified by:

advance in interface Iter

Returns:

The iterator itself.

@Deprecated
public int hashCode()

Deprecated.

Overrides:

hashCode in class Object

equals

@Deprecated
public boolean equals(Object obj)

Overrides:

equals in class Object

getRef

public DBIDRef getRef()

Description copied from interface: DBIDRefIter

Get the current DBIDRef.

Specified by:

getRef in interface DBIDRefIter

Returns:

DBID reference
