pack-priv final Class ByteArrayAccess

extends Object
Class Inheritance
Imports
java.lang.invoke.MethodHandles, .VarHandle, java.nio.ByteOrder
Optimized methods for converting between byte[] and int[]/long[], both for big endian and little endian byte orders. NOTE that ArrayIndexOutOfBoundsException will be thrown if the bounds checks failed. This class may also be helpful in improving the performance of the crypto code in the SunJCE provider. However, for now it is only accessible by the message digest implementation in the SUN provider.
