Interface | Description |
---|---|
Address |
The
Address interface serves as a base class for all SNMP
transport addresses. |
AssignableFromByteArray |
The
AssignableFromByteArray interface describes objects whose
value can be set from a byte array and converted back to a byte array. |
AssignableFromIntArray |
The
AssignableFromIntArray interface describes objects whose
value can be set from an int array and converted back to an int array. |
AssignableFromInteger | |
AssignableFromLong | |
AssignableFromString | |
Variable |
The
Variable interface defines common attributes of all SNMP
variables. |
VariantVariableCallback |
The
VariantVariableCallback can be implemented by
objects that want to intercept/monitor reading and writing of
a VariantVariable 's value. |
Class | Description |
---|---|
AbstractVariable |
The
Variable abstract class is the base class for all SNMP
variables. |
BitString |
The
BitString class represents the obsolete SMI type
BIT STRING which has been defined in RFC 1442 (an SNMPv2 draft) but
which has been obsoleteted by RFC 1902 and RFC 2578. |
Counter32 |
The
Counter32 class allows all the functionality of unsigned
integers but is recognized as a distinct SMI type, which is used for
monotonically increasing values that wrap around at 2^32-1 (4294967295). |
Counter64 |
The
Counter64 class represents a 64bit unsigned integer type. |
Gauge32 |
The
Gauge32 class is indistinguishable from
UnsingedInteger32 . |
GenericAddress |
The
GenericAddress implements the decorator and factory
design pattern to provide a generic address type. |
Integer32 |
The
Integer32 represents 32bit signed integer values for SNMP. |
IpAddress |
The
IpAddress class represents an IPv4 address SNMP variable. |
Null |
The
Null class represents SMI Null and the derived
SMIv2 exception syntaxes. |
OctetString |
The
OctetString class represents the SMI type OCTET STRING. |
OID |
The Object Identifier Class.
|
Opaque |
The
Opaque class represents the SMI type Opaque which is used
to transparently exchange BER encoded values. |
ReadonlyVariableCallback |
This abstract class helps to implement a
VariantVariableCallback
for a read-only Variable. |
SMIAddress |
A
SMIAddress is an address that is defined by the Structure
of Management Information (SMI) and can be thereby serialized through the
Basic Encoding Rules (BER) used by the SNMP protocol. |
SMIConstants |
The
SMIConstants defines the tag values for SMI syntax types. |
SshAddress |
The
SshAddress represents a SSH transport addresses as defined
by RFC 5592 SnmpSSHAddress textual convention. |
TcpAddress |
The
TcpAddress represents TCP/IP transport addresses. |
TimeTicks |
The
TimeTicks class represents the time in 1/100 seconds
since some epoch (which should be have been defined in the
corresponding MIB specification). |
TlsAddress |
The
SshAddress represents a SSH transport addresses as defined
by RFC 5953 SnmpTSLAddress textual convention. |
TransportIpAddress |
The
TransportIpAddress is the abstract base class for all
transport addresses on top of IP network addresses. |
UdpAddress |
The
UdpAddress represents UDP/IP transport addresses. |
UnsignedInteger32 |
UnsignedInteger32 type is an SNMP type that represents unsigned 32bit
integer values (0 to 4294967295).
|
VariableBinding | |
VariantVariable |
The
VariantVariable provides a decorator for any type
of Variable instance, to be able to intercept or monitor variable
value modification by using a VariantVariableCallback . |
The org.snmp4j.smi
classes are capable of BER encoding and
decoding themself to/from a byte stream. In addition, the SMI data type
classes provide convenient functions for manipulating their content.
The VariantVariable
is a special class that can be
used in command responder applications to intercept access to
a SMI value.
import org.snmp4j.smi.*; ... VariableBinding vb = new VariableBinding(new OID("1.3.6.1.2.1.1.4.0")); vb.setValue(new OctetString("SNMP4J Text")); ... vb = new VariableBinding(); vb.setOid(new OID(new int[] { 1,3,6,1,2,1,1,2,0 })); ... vb = new VariableBinding(vb.getOid(), new IpAddress("255.255.255.255")); ... vb = new VariableBinding(vb.getOid(), new Gauge32(2^32-1)); int syntax = vb.getSyntax(); if (syntax != SMIConstants.SYNTAX_GAUGE32) { // never reached } else { long value = ((UnsignedInteger32)vb.getValue()).getValue(); System.out.println(vb.getOid() + " = " + value); // prints: 1.3.6.1.2.1.1.2.0 = 4294967295 } ...
