Class Combine.GammaCodedIntIterator

java.lang.Object
  it.unimi.dsi.fastutil.ints.AbstractIntIterator
      it.unimi.di.mg4j.tool.Combine.GammaCodedIntIterator

All Implemented Interfaces:

IntIterator, Closeable, Iterator<Integer>

Enclosing class:

Combine

protected static final class Combine.GammaCodedIntIterator
extends AbstractIntIterator
implements Closeable

A partial IntIterator implementation based on γ-coded integers.

Instances of this class adapt an InputBitStream to an IntIterator by reading γ-coded integers. The implementation is partial because hasNext() always returns true—the user must know in advance how many times nextInt() may be safely called.

Combine.GammaCodedIntIterator(InputBitStream inputBitStream)

Method Summary

void	close() Delegates to the underlying InputBitStream.
boolean	hasNext() Returns true.
