Constructor Detail

TroveHashSetModifiableDBIDs.DBIDItr

public TroveHashSetModifiableDBIDs.DBIDItr(gnu.trove.impl.hash.TIntHash hash)

Constructor.

Parameters:

hash - Trove hash

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

advance

public void advance()

Description copied from interface: Iter

Moves the iterator forward to the next entry.

Specified by:

advance in interface Iter

getIntegerID

public int getIntegerID()

Description copied from interface: DBIDRef

Return the integer value of the object ID, if possible.

Specified by:

getIntegerID in interface DBIDRef

Returns:

integer id

getDBID

public DBID getDBID()

Description copied from interface: DBIDIter

Get the referenced DBID. Efficiency note: this may require materialization of a DBID object - if possible, use DBIDRef based APIs instead.

Specified by:

getDBID in interface DBIDIter

Specified by:

getDBID in interface DBIDRef

Returns:

referenced DBID

sameDBID

public boolean sameDBID(DBIDRef other)

Description copied from interface: DBIDRef

Compare the current value of two referenced DBIDs.

Specified by:

sameDBID in interface DBIDRef

Parameters:

other - Other DBID reference (or DBID)

Returns:

true when the references currently refer to the same.

compareDBID

public int compareDBID(DBIDRef o)

Description copied from interface: DBIDRef

Compare two objects by the value of the referenced DBID.

Specified by:

compareDBID in interface DBIDRef

Parameters:

o - Other DBID or object

Returns:

-1, 0 or +1
