Method Detail
-
getSyntax
public int getSyntax()
Description copied from class:AbstractVariable
Gets the ASN.1 syntax identifier value of this SNMP variable.- Specified by:
getSyntax
in interfaceVariable
- Overrides:
getSyntax
in classOctetString
- Returns:
- an integer value less than 128 for regular SMI objects and a value greater or equal than 128 for exception values like noSuchObject, noSuchInstance, and endOfMibView.
-
encodeBER
public void encodeBER(java.io.OutputStream outputStream) throws java.io.IOException
Description copied from class:AbstractVariable
Encodes aVariable
to anOutputStream
.- Specified by:
encodeBER
in interfaceBERSerializable
- Overrides:
encodeBER
in classOctetString
- Parameters:
outputStream
- anOutputStream
.- Throws:
java.io.IOException
- if an error occurs while writing to the stream.
-
decodeBER
public void decodeBER(BERInputStream inputStream) throws java.io.IOException
Description copied from class:AbstractVariable
Decodes aVariable
from anBERInputStream
.- Specified by:
decodeBER
in interfaceBERSerializable
- Overrides:
decodeBER
in classOctetString
- Parameters:
inputStream
- anBERInputStream
containing a BER encoded byte stream.- Throws:
java.io.IOException
- if the stream could not be decoded by using BER rules.
-
setValue
public void setValue(OctetString value)
-
toString
public java.lang.String toString()
Description copied from class:OctetString
Returns a String representation of thisOctetString
. If theOctetString
contains non-printable characters, a hex-string representation is returned unlessSNMP4JSettings.getDefaultNonPrintableEscapeCharacter()
returns a non-null
character that is then used to replace all non-printable characters in the output.- Specified by:
toString
in interfaceVariable
- Overrides:
toString
in classOctetString
- Returns:
- a String representation of this
OctetString
.
-
clone
public java.lang.Object clone()
Description copied from interface:Variable
Clones this variable. Cloning can be used by the SNMP4J API to better support concurrency by creating a clone for internal processing. The content of this object is independent to the content of the clone. Thus, changes to the clone will have no effect to this object.- Specified by:
clone
in interfaceVariable
- Overrides:
clone
in classOctetString
- Returns:
- a new instance of this
Variable
with the same value.
