public class PositionableByteArrayInputStream
extends ByteArrayInputStream

Descendant of ByteArrayInputStream that allows to change the offset and length. The standard ByteArrayInputStream can only wrap a fixed part of its underlying byte array (this byte array being managed by another source). As the ByteArrayInputStream is used as source for other streams, it is not possible to create a new ByteArrayInputStream if the part of the underlying byte array used to read changes. Therefore this class allows to change the offset and length of the part to use. Furthermore, it also allows to change the underlying byte array.
