Changes from version 1.3 to 1.4:
- Replaced SNMPInteger values in Get and GetNext requests with SNMP Nulls
- Changed SNMP TimeTicks in trap sender timestamp to 1/100ths of second rather
than 1/1000ths
- Restricted SNMPTimeTicks to be 32-bit quantity (rather than arbitrarily large,
which caused problems with some receivers)
- Added PrintWriter for error reporting in AgentListener and TrapListener interfaces
so error reporting can be directed as desired (rather than always to System.out)
- Changed internal representation of SNMPObjectIdentifier to array of longs to accept
OID components up to 2^32 - 1 (thanks to Norman Elton)
- Changed toString() methods to utilize StringBuffer internally, for efficiency
(thanks to Philip Yarra)
- Added radix specification to SNMPInteger class toString() method
- Improved error handling:
- Messages and PDUs perform more detailed qualification of contents, reporting more
specific errors (rather than passing on generic Java exception types)
- Agent Interface now catches and reports all exceptions
- Fixed bug in SNMPv1AgentInterface, in which handled OIDs checked by reference
rather than by value (thanks to Roman Levandovsky)
- Added equals() and hashCode() methods to SNMP object subclasses for use in collections
- Added support for SNMPv2 traps and inform request messages. Note that as a result the
1.4 version of the package is not directly backward-compatible with the 1.3 version,
as all classes related to trap messages have been qualified to indicate whether the
trap is a v1 or v2 trap. Thus applications which use traps will need to be changed
to use the 1.4 version package; however, the changes should be simple textual
substitutions, e.g., changing all references to SNMPTrapPDU to SNMPv1TrapPDU.
- Added build scripts for GNU Make and Apache Ant
