public class BitString
extends OctetString

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. This type is provided for compatibility only and should not be used for new applications.

Since:

1.7.4

Constructor Details

BitString

public BitString()

Deprecated.

The BIT STRING type has been temporarily defined in RFC 1442 and obsoleted by RFC 2578. Use OctetString (i.e. BITS syntax) instead.

Creates a BIT STRING value.

Method Details

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 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(OutputStream outputStream)
               throws 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:

IOException - if an error occurs while writing to the stream.

decodeBER

public void decodeBER(BERInputStream inputStream)
               throws IOException

Description copied from class: AbstractVariable

Decodes a Variable from an BERInputStream.

Specified by:

decodeBER in interface BERSerializable

Overrides:

decodeBER in class OctetString

Parameters:

inputStream - an BERInputStream containing a BER encoded byte stream.

Throws:

IOException - if the stream could not be decoded by using BER rules.

clone

public 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.
