Class FileLinesBigList.FileLinesIterator

java.lang.Object

it.unimi.dsi.sux4j.io.FileLinesBigList.FileLinesIterator

All Implemented Interfaces:

it.unimi.dsi.fastutil.BidirectionalIterator<it.unimi.dsi.lang.MutableString>, it.unimi.dsi.fastutil.BigListIterator<it.unimi.dsi.lang.MutableString>, it.unimi.dsi.fastutil.objects.ObjectBidirectionalIterator<it.unimi.dsi.lang.MutableString>, it.unimi.dsi.fastutil.objects.ObjectBigListIterator<it.unimi.dsi.lang.MutableString>, it.unimi.dsi.fastutil.objects.ObjectIterator<it.unimi.dsi.lang.MutableString>, it.unimi.dsi.io.SafelyCloseable, Closeable, AutoCloseable, Iterator<it.unimi.dsi.lang.MutableString>

Enclosing class:

FileLinesBigList

public static final class FileLinesBigList.FileLinesIterator
extends Object
implements it.unimi.dsi.fastutil.objects.ObjectBigListIterator<it.unimi.dsi.lang.MutableString>, it.unimi.dsi.io.SafelyCloseable

An iterator over the lines of a FileLinesBigList. 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.

2.1
