Create a new instance with the provided Comparator.

Parameters:

comparator - The comparator to set.

ElitistSelection

public ElitistSelection(ElitistSelection copy)

Create a copy of the provided instance.

Parameters:

copy - The instance to copy.

Method Detail

Set the comparator to be used.

Parameters:

comparator - The value to set.

getComparator

public Comparator<Selection.Entry<E>> getComparator()

Get the current comparator.

Returns:

The current comparator instance.

select
