Class DerInputBuffer

java.lang.Object

java.io.InputStream

java.io.ByteArrayInputStream

org.mozilla.jss.netscape.security.util.DerInputBuffer

All Implemented Interfaces:

Closeable, AutoCloseable, Cloneable

class DerInputBuffer
extends ByteArrayInputStream
implements Cloneable

DER input buffer ... this is the main abstraction in the DER library which actively works with the "untyped byte stream" abstraction. It does so with impunity, since it's not intended to be exposed to the anyone who could violate the "typed value stream" DER model and hence corrupt the input stream of DER values.
