Package org.snmp4j.asn1

package org.snmp4j.asn1

Provides classes and interfaces for the mapping between Abstract Syntax Notation One (ASN.1) formatted values and their transfer syntax according to the Basic Encoding Rules (BER).

The org.snmp4j.asn1 classes are capable of serializing of ASN.1 formatted values into a byte stream and deserializing the same from a byte stream. There are three groups of classes/interfaces in this package:

• The BER class implements the BER serialization and deserialization by providing static methods for encoding/decoding of primitive ASN.1 and Structure of Management Information (SMI) data types.
• The BERSerializable interface provides a common interface for all objects that are (de)serializable according to the Basic Encoding Rules (BER).
• The BERInputStream and the BEROutputStream provide optimized implementations for the serialization and deserialization of the InputStream and OutputStream abstract classes.

The following UML class diagram shows the most important classes of the org.snmp4j.asn1 package and their relationships (relationships to other packages are not shown):

Package	Description
org.snmp4j	Provides classes and interfaces for creating, sending, and receiving SNMP messages.

Class	Description
BER	The BER class provides utility methods for the BER encoding and decoding.
BER.MutableByte	The MutableByte class serves for exchanging type information from the various decode* methods.
BERInputStream	The BERInputStream class wraps a ByteBuffer and implements the InputStream abstract class.
BEROutputStream	The BEROutputStream class wraps a ByteBuffer to support BER encoding.
BERSerializable	The interface BERSerializable has to be implemented by any data type class that needs to be serialized using the Basic Encoding Rules (BER) that provides enconding rules for ASN.1 data types.
