              it.unimi.dsi.sux4j.io.FileLinesList.FileLinesIterator

All Implemented Interfaces:

BidirectionalIterator<MutableString>, ObjectBidirectionalIterator<MutableString>, ObjectIterator<MutableString>, ObjectListIterator<MutableString>, SafelyCloseable, Closeable, Iterator<MutableString>, ListIterator<MutableString>

Enclosing class:

FileLinesList

public static final class FileLinesList.FileLinesIterator
extends AbstractObjectListIterator<MutableString>
implements SafelyCloseable

An iterator over the lines of a FileLinesList. Instances of this class open an InputStream, and thus should be closed after usage. A “safety-net” finaliser tries to take care of the cases in which closing an instance is impossible.

Constructor Summary

Method Summary

void	close()
protected void	finalize()
boolean	hasNext()
boolean	hasPrevious()
MutableString	next()
int	nextIndex()
