      • iter

        public DBIDIter iter()
        Description copied from interface: DBIDs
        Get a DBID iterator (a more efficient API).

        Example: 

         
 for(DBIDIter iter = ids.iter(); iter.valid(); iter.advance()) {
   NumberVector vec = relation.get(iter); // iter is a temporary object reference
 }
        Specified by:
        iter in interface DBIDs
        Returns:
        iterator

      • size

        public int size()
        Description copied from interface: DBIDs
        Retrieve the collection / data size.
        Specified by:
        size in interface DBIDs
        Returns:
        collection size

      • contains

        public boolean contains​(DBIDRef 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.
