snmp
Class SNMPBERCodec
java.lang.Object
snmp.SNMPBERCodec
- public class SNMPBERCodec
- extends java.lang.Object
SNMPBERCodec defines methods for converting from ASN.1 BER encoding to SNMPObject subclasses. The extraction
process usually produces a tree structure of objects with an SNMPSequence object at the root; this
is the usual behavior when a received encoded message is received from an SNMP device.
Method Summary |
static byte[] |
encodeLength(int length)
Utility function for encoding a length as a BER byte sequence |
static SNMPObject |
extractEncoding(snmp.SNMPTLV theTLV)
Extracts an SNMP object given its type, length, value triple as an SNMPTLV object. |
static snmp.SNMPTLV |
extractNextTLV(byte[] enc,
int position)
Extracts the type, length and value of the SNMP object whose BER encoding begins at the
specified position in the given byte array. |

extractEncoding
public static SNMPObject extractEncoding(snmp.SNMPTLV theTLV)
throws SNMPBadValueException
- Extracts an SNMP object given its type, length, value triple as an SNMPTLV object.
Called by SNMPObject subclass constructors.
- Throws:
SNMPBadValueException
- Indicates byte array in value field is uninterprettable for
specified SNMP object type.

throws SNMPBadValueException
- Extracts the type, length and value of the SNMP object whose BER encoding begins at the
specified position in the given byte array. Throws an SNMPBadValueException if there's
any problem with the extraction.
- Throws:
