Description
Interface Summary | |
---|---|
ConnectionOrientedTransportMapping | Transport mappings for connection oriented transport protocols have to implement this interface. |
MessageLengthDecoder | The MessageLengthDecoder needs to be implemented for connection
oriented transport mappings, because those transport mappings have no message
boundaries. |
TransportListener | The TransportListener interface is implemented by objects
that process incoming messages from TransportMapping s, for
example MessageDispatcher . |
TransportStateListener | The TransportStateListener interface can be implemented
to monitor the connection state for connection oriented transport mappings. |
Class Summary | |
---|---|
AbstractTransportMapping | The AbstractTransportMapping provides an abstract
implementation for the message dispatcher list and the maximum inbound
message size. |
DefaultTcpTransportMapping | The DefaultTcpTransportMapping implements a TCP transport
mapping with the Java 1.4 new IO API. |
DefaultTcpTransportMapping.SnmpMesssageLengthDecoder | |
DefaultUdpTransportMapping | The DefaultUdpTransportMapping implements a UDP transport
mapping based on Java standard IO and using an internal thread for
listening on the inbound socket. |
MessageLength | The MessageLength object contains information about the
length of a message and the length of its header. |
TcpTransportMapping | The TcpTransportMapping is the abstract base class for
TCP transport mappings. |
TransportMappings | The TransportMappings factory can be used to create a transport
mapping for an address class. |
TransportStateEvent | The TransportStateEvent describes a state change for
a transport connection. |
UdpTransportMapping | The UdpTransportMapping is the abstract base class for
UDP transport mappings. |
Exception Summary | |
---|---|
UnsupportedAddressClassException | The UnsupportedAddressClassException indicates a message
exception caused by unsupported address class. |
Provides transport protocol mappings for SNMP.
The org.snmp4j.transport
classes are capable of sending and
receiving byte messages to and from a network using transport mapping specific
transport protocol. All SNMP4J transport mappings have to implement the
org.snmp4j.TransportMapping
interface. SNMP4J supports two
transport mappings for the transport protocols UDP and TCP:
DefaultUdpTransportMapping
class.
DefaultTcpTransportMapping
using the java.nio
package.
Additional transport mappings can be easily added. It is sufficient to
implement the org.snmp4j.TransportMapping
interface and add
an instance of that class to the Snmp
(or MessageDispatcher
)
object. To be able to lookup a transport mapping by an Address
class via the TransportMappings
(as Snmp
does
for notification listeners), a transport mapping has to be registered
in a transport mapping registration file. The default file is
transports.properties
in the org.snmp4j.transport
package. To use a different file, set the system property
org.snmp4j.transportMappings
.
Connection-oriented transport mappings like TCP should implement
the ConnectionOrientedTransportMapping
interface to support
MessageLengthDecoder
and TransportStateListener
.
The following UML class diagram shows the classes of the
org.snmp4j.transport
package and their relationships
