Class IntArrayPredicateIterator

java.lang.Object

org.carrot2.util.IntArrayPredicateIterator

All Implemented Interfaces:

Iterator<Integer>

public final class IntArrayPredicateIterator
extends Object
implements Iterator<Integer>

Iterates over ranges between elements for which a given predicate returns true . The returned range may be of zero length (getLength()).

An example probably best explains what this class does. Consider the following array:

 [SEP, SEP, 1, SEP]
 

where SEP is something for which the predicate returns true. If so, then the returned subranges would be equal to (start index, length):

 [0,0]  (empty range before the first separator)
 [1,0]  (empty range after the first separator)
 [2,1]  ([1])
 [4,0]  (empty range after last separator)
