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 interface Variable

Overrides:

getSyntax in class OctetString

Returns:

an integer value < 128 for regular SMI objects and a value >= 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 a Variable to an OutputStream.

Specified by:

encodeBER in interface BERSerializable

Overrides:

encodeBER in class OctetString

Parameters:

outputStream - an OutputStream.

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 a Variable from an InputStream.

Specified by:

decodeBER in interface BERSerializable

Overrides:

decodeBER in class OctetString

Parameters:

inputStream - an InputStream 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: AbstractVariable

Gets a string representation of the variable.

Specified by:

toString in interface Variable

Overrides:

toString in class OctetString

Returns:

a string representation of the variable's value.

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 interface Variable

Overrides:

clone in class OctetString

Returns:

a new instance of this Variable with the same value.
