Method Detail

sort

void sort()

Sort the DBID set.

sort

void sort(Comparator<? super DBIDRef> comparator)

Sort the DBID set.

Parameters:

comparator - Comparator to use

sort

void sort(int start,
        int end,
        Comparator<? super DBIDRef> comparator)

Sort the DBID set.

Parameters:

start - Starting index, for partial sorting

end - End index, for partial sorting (exclusive)

comparator - Comparator to use

remove

DBID remove(int i)

Remove the i'th entry (starting at 0)

Parameters:

i - Index

Returns:

value removed

set

DBID set(int i,
       DBIDRef newval)

Replace the i'th entry (starting at 0)

Parameters:

i - Index

newval - New value

Returns:

previous value

swap

void swap(int a,
        int b)

Swap DBIDs add positions a and b.

Parameters:

a - First position

b - Second position

iter

DBIDArrayMIter iter()

Description copied from interface: ModifiableDBIDs

Get a modifiable DBID iterator (a more efficient API). usage example:

 for(DBIDMIter iter = ids.iter(); iter.valid(); iter.advance()) {
   DBID id = iter.getDBID();
   iter.remove();
 }
