Class Asn1InputStream

java.lang.Object

  +--com.outbackinc.services.protocol.snmp.Asn1InputStream
public class Asn1InputStream
extends java.lang.Object

The Asn1InputStream takes a byte buffer and decodes it based on standard ASN.1 syntax. This class is provided for implementers of future SNMPv3 security models, otherwise it should not be normally used in JSNMP applications.
