Method Detail

next

public abstract Comparable next()

Moves the iteration to the next facet

Specified by:

next in interface Iterator<Comparable>

Returns:

the next facet value

next

public abstract Comparable next(int minHits)

Moves the iteration to the next facet whose hitcount >= minHits. returns null if there is no facet whose hitcount >= minHits. Hence while using this method, it is useless to use hasNext() with it. After the next() method returns null, calling it repeatedly would result in undefined behavior

Returns:

The next facet value. It returns null if there is no facet whose hitcount >= minHits.

format

public abstract String format(Object val)
