Class SnmpServer

java.lang.Object
  |
  +--com.adventnet.snmp.beans.SnmpServer

Direct Known Subclasses:

SnmpRequestServer, SnmpTarget

public class SnmpServer

extends java.lang.Object

implements java.io.Serializable

This class maintains all the resources required for Snmp manager applications and applets. The resources are like SnmpAPI, SnmpSession, MibOperations and etc.The beans component like SnmpTarget and SnmpRequestServer extends this class. For every instance of these beans the SnmpServer uses the same resources.

Constructor Detail

SnmpServer

SnmpServer(SnmpSession ses,
           MibOperations mib)

SnmpServer

SnmpServer()

Use this constructor for applications. Use for applets only if you want to prevent use of SAS. MIB loading from applets may fail from this SnmpServer instance if you use this constructor.This matters only for the first SnmpServer instance, and subsequent instances will use the same SNMP mechanisms.

SnmpServer

SnmpServer(java.applet.Applet applet)

Use this constructor for applets. Applets will try and use SAS, and if unsuccessful will use local sockets. MIB loading from applets may fail from this SnmpServer instance if you use this constructor. This matters only for the first SnmpServer instance, and subsequent instances will use the same SNMP mechanisms.

SnmpServer

SnmpServer(int localPort,
           java.lang.String sessionName)

Use this constructor for applications with the specified local port and specified session name . Use for applets only if you want to prevent use of SAS. MIB loading from applets may fail from this SnmpServer instance if you use this constructor. This matters only for the first SnmpServer instance, and subsequent instancesi will use the same SNMP mechanisms.

SnmpServer

SnmpServer(java.applet.Applet applet,
           int localPort,
           java.lang.String sessionName)

Use this constructor for applets with the specified local port and specified session name . Applets will try and use SAS, and if unsuccessful will use local sockets. MIB loading from applets may fail from this SnmpServer instance if you use this constructor. This matters only for the first SnmpServer instance, and subsequent instances will use the same SNMP mechanisms.

SnmpServer

SnmpServer(int protocol,
           ProtocolOptions options)

Use this constructor when using protocols other than UDP/IP with the specified protocol and the protocol options. Applets will try and use SAS, and if unsuccessful will use local sockets. MIB loading from applets may fail from this SnmpServer instance if you use this constructor. This matters only for the first SnmpServer instance, and subsequent instances will use the same SNMP mechanisms.

SnmpServer

SnmpServer(java.lang.String[] localAddrs,
           java.lang.String sessionName)

Use this constructor for applications in which the session needs to be bound to some local address. Usually, the session will be shared across different instances of this class. If seperate session needs to be used, then specify unique sessionNames for the instances created.

Parameters:

localAddrs - The local addresses to which the session needs to be bound.

sessionName - Specify unique sessionNames for the instances which need to use different SnmpSession instances to send data.
