public Class ImageStream

extends Object
Class Inheritance
Imports
java.nio.ByteBuffer, .ByteOrder, java.util.Arrays, .Objects

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.
