Class Inheritance

java.lang.Object
jdk.internal.jrtfs.JrtDirectoryStream

All Implemented Interfaces

java.nio.file.DirectoryStream, java.lang.Iterable, java.io.Closeable, java.lang.AutoCloseable

Imports

java.nio.file.DirectoryStream, .ClosedDirectoryStreamException, .DirectoryIteratorException, .NotDirectoryException, .Path, java.util.Iterator, .Objects, .NoSuchElementException, java.io.IOException

DirectoryStream implementation for jrt file system implementations.

Implementation Note

This class needs to maintain JDK 8 source compatibility. It is used internally in the JDK to implement jimage/jrtfs access, but also compiled and delivered as part of the jrtfs.jar to support access to the jimage file provided by the shipped JDK by tools running on JDK 8.

Method Detail

close back to summary

close	back to summary
public synchronized void close() throws IOException Implements java.io.Closeable.close. Doc from java.io.Closeable.close. Closes this stream and releases any system resources associated with it. If the stream is already closed then invoking this method has no effect. As noted in `AutoCloseable#close()`, cases where the close may fail require careful attention. It is strongly advised to relinquish the underlying resources and to internally mark the `Closeable` as closed, prior to throwing the `IOException`. Annotations @Override Exceptions IOException: if an I/O error occurs

public synchronized void close() throws IOException

Implements java.io.Closeable.close.

Doc from java.io.Closeable.close.

Closes this stream and releases any system resources associated with it. If the stream is already closed then invoking this method has no effect.

As noted in AutoCloseable#close(), cases where the close may fail require careful attention. It is strongly advised to relinquish the underlying resources and to internally mark the Closeable as closed, prior to throwing the IOException.
