All Implemented Interfaces:

MOInput

public class PropertyMOInput
extends Object
implements MOInput

The PropertyMOInput can be used to load MIB data from a properties file.

The format of the properties file is as follows:

   snmp4j.agent.cfg.contexts={s|x}<context1>[,{s|x}<context2>...]
   snmp4j.agent.cfg.oid[.ctx.<context>].<oid>=[<numRows>:<numCols>]
   snmp4j.agent.cfg.oid[.ctx.<context>].<oid>=[{<format>}<value>]
   snmp4j.agent.cfg.index[.ctx.<context>].oid.<rowIndex>={o}<index>
   snmp4j.agent.cfg.value[.ctx.<context>].oid.<rowIndex>.<colIndex>=[{<format>}<value>]
 

where text enclosed in [] is optional and

• context1 - is a SNMPv3 context name as UTF-8 string (format {s}) or a hexadecimal string (format {x}).
• context - is a SNMPv3 context name as UTF-8 string if that string does not contain any ISO control characters, otherwise a hexdecimal representation separated by a colon (:).
• format - one of
  • u - an Unsigned32 value.
  • i - an Integer32 value.
  • s - an OctetString value.
  • x - an OctetString value in hexadecimal format (separated by :).
  • d - an OctetString value in decimal format (separated by .).
  • b - an OctetString value in decimal format (separated by ' ' per byte).
  • n - a Null value.
  • o - an OID value as dotted string where string parts may be specified directly enclosed in single quotes (') and the to an OID converted value of a variable/oid instance may be specified in the format [#]{<name/oid>}. The value of the variable will be included into the OID with prependend length if the # is used in the format string otherwise no length will be included.
  • t - a TimeTicks value as an unsigned long value.
  • a - a IpAddress value.
  • $ - gets the value from the variable or object instance specified by the name/oid following the $.
• value - a variable value in the format specified by format.
• numRows - the number of rows in the table.
• numCols - the number of columns in the table.
• rowIndex - the row index as a zero based unsigned integer.
• colIndex - the column index as a zero based unsigned integer.
• index - the OID value of the row's index.

Throws:

IOException

skipManagedObject

public void skipManagedObject(MOInfo mo)
                       throws IOException

Description copied from interface: MOInput

Skips to the end of the specified managed object's configuration.

Specified by:

skipManagedObject in interface MOInput

Parameters:

mo - a MOInfo instance.

Throws:

IOException - if the input stream cannot be read.

createVariableFromString

public org.snmp4j.smi.Variable createVariableFromString(String value,
 Class<? extends org.snmp4j.smi.Variable> returnType)

Parses a string of the format

 OID={type}value where <type> is one of
 the following single characters enclosed by '{' and '}':
  i                     Integer32
  u                     UnsignedInteger32, Gauge32
  s                     OCTET STRING
  x                     OCTET STRING specified as hex string where
                        bytes separated by colons (':').
  d                     OCTET STRING specified as decimal string
                        where bytes are separated by dots ('.').
  n                     Null
  o                     OBJECT IDENTIFIER
  t                     TimeTicks
  a                     IpAddress
  b                     OCTET STRING specified as binary string where
                        bytes are separated by spaces.
  $<variableName>     where <variableName> is the name of a predefined
                        variable or the OID of a variable of the agent's
                        MIB.
