Method Detail

setCurrent

protected final void setCurrent(IntIntPair cur)

Set the current pair.

Parameters:

cur - new current pair.

current

public final IntIntPair current()

Return current pair. Marked as final to avoid bad implementations. If you intend to override this, just implement the interface!

current in interface PairSortedGeneratorInterface

Returns:

current pair, null if there are no more pairs

next

public final IntIntPair next()

Return next pair. Marked as final to avoid bad implementations. If you intend to override this, just implement the interface!

Specified by:

next in interface PairSortedGeneratorInterface

Returns:

next pair, null if there are no more pairs

advance

protected abstract IntIntPair advance()

Main advance method.
