java.io.InputStream

org.apache.commons.io.input.UnsynchronizedByteArrayInputStream

All Implemented Interfaces:

Closeable, AutoCloseable

public class UnsynchronizedByteArrayInputStream
extends InputStream

This is an alternative to ByteArrayInputStream which removes the synchronization overhead for non-concurrent access; as such this class is not thread-safe.
