Class BitSetIterator

java.lang.Object

qilin.util.BitSetIterator

public class BitSetIterator
extends Object

A fast enumerator for sparse bit sets. When the enumerator is created, it takes a snapshot of the underlying BitVector, and iterates through the set bits. Note that this class almost implements the Iterator interface, but it doesn't because the return type of next is int rather than Object.

Method Summary

Modifier and Type	Method	Description
boolean	hasNext()	Returns true if there are more set bits in the BitVector; false otherwise.
