parent

final KNNResult<?> parent

The true list.

Constructor Detail

public KNNUtil.DBIDView(KNNResult<?> parent)

Constructor.

Parameters:

parent - Owner

Method Detail

get

public DBID get(int i)

Description copied from interface: ArrayDBIDs

Get the i'th entry (starting at 0)

Specified by:

get in interface ArrayDBIDs

Parameters:

i - Index

Returns:

DBID of i'th entry.

iterator

public Iterator<DBID> iterator()

Description copied from interface: DBIDs

Retrieve Iterator access to the IDs.

Specified by:

iterator in interface DBIDs

Specified by:

iterator in interface Iterable<DBID>

Returns:

an iterator for the IDs

iter

public DBIDIter iter()

Description copied from interface: ArrayDBIDs

Iterable

Specified by:

iter in interface ArrayDBIDs

Specified by:

iter in interface DBIDs

Returns:

Iterator

size

public int size()

Description copied from interface: ArrayDBIDs

Size of the DBID "collection".

Specified by:

size in interface ArrayDBIDs

Specified by:

size in interface DBIDs

Returns:

size

contains

public boolean contains(DBID o)

Description copied from interface: DBIDs

Test whether an ID is contained.

Specified by:

contains in interface DBIDs

Parameters:

o - object to test

Returns:

true when contained

isEmpty

public boolean isEmpty()

Description copied from interface: DBIDs

Test for an empty DBID collection.

Specified by:

isEmpty in interface DBIDs

Returns:

true when empty.

binarySearch

@Deprecated
public int binarySearch(DBID key)

Deprecated.

A binary search does not make sense here, as the (read-only) result is sorted by distance, not DBID. Thus unsupported.

Specified by:

binarySearch in interface ArrayDBIDs

Parameters:

key - Key to search for

Returns:

Offset of key
