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 theBEROutputStream
provide optimized implementations for the serialization and deserialization of theInputStream
andOutputStream
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):
-
ClassDescriptionThe BER class provides utility methods for the BER encoding and decoding.The
MutableByte
class serves for exchanging type information from the various decode* methods.TheBERInputStream
class wraps aByteBuffer
and implements theInputStream
abstract class.TheBEROutputStream
class wraps aByteBuffer
to support BER encoding.The interfaceBERSerializable
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.
