Field Detail

m_value

private BigInteger m_value

The internal 64-bit unsigned quantity implemented as a 64-bit signed quantity

ASNTYPE

public static final byte ASNTYPE

The ASN.1 value for an unsigned integer value. BEWARE this value will conflict with the SnmpSMI.SMI_COUNTER32 value. This object should not be dynamically registered with the SNMP library

Constructor Detail

SnmpCounter64

public SnmpCounter64()

Default class constructor. Constructs the object with a value of zero(0).

SnmpCounter64

public SnmpCounter64(long value)

Constructs a SnmpCounter64 object with the specified value.

Parameters:

value - The new 64-bit value.

SnmpCounter64

public SnmpCounter64(BigInteger value)

Constructs a SnmpCounter64 object with the specified value.

Parameters:

value - The new 64-bit value.

SnmpCounter64

public SnmpCounter64(SnmpCounter64 second)

Class copy constructor. Constructs a new object with the same value as the passed object.

Parameters:

second - The object to copy the value from.

Method Detail

getValue

public BigInteger getValue()

Used to retreive the 64-bit unsigned value.

Returns:

The internal 64-bit value.

setValue

public void setValue(BigInteger value)

Used to set the 64-bit unsigned quantity. If the value exceeds 64-bit then the upper 64-bits will be silently truncated from the value.

Parameters:

value - The new value for the object

typeId

public byte typeId()

Used to retreive the ASN.1 type for this object.

Specified by:

typeId in interface SnmpSyntax

Returns:

The ASN.1 value for the SnmpCounter64

encodeASN

public int encodeASN(byte[] buf,
                     int offset,
                     AsnEncoder encoder)
              throws AsnEncodingException

Used to encode the integer value into an ASN.1 buffer. The passed encoder defines the method for encoding the data.

Specified by:

encodeASN in interface SnmpSyntax

Parameters:

buf - The location to write the encoded data

offset - The start of the encoded buffer.

encoder - The ASN.1 encoder object

Returns:

The byte immediantly after the last encoded byte.

Throws:

AsnEncodingException - Thrown if an encoding error occurs

decodeASN

public int decodeASN(byte[] buf,
                     int offset,
                     AsnEncoder encoder)
              throws AsnDecodingException

Used to decode the integer value from the ASN.1 buffer. The passed encoder is used to decode the ASN.1 information and the integer value is stored in the internal object.

Specified by:

decodeASN in interface SnmpSyntax

Parameters:

buf - The encoded ASN.1 data

offset - The offset of the first byte of data

encoder - The ASN.1 decoder object.

Returns:

The byte immediantly after the last decoded byte of information.

Throws:

AsnDecodingException - Thrown if an encoding error occurs

duplicate

public SnmpSyntax duplicate()

Returns a duplicte of the current object

Specified by:

duplicate in interface SnmpSyntax

Returns:

A duplciate copy of the current object

clone

public Object clone()

Returns a duplicte of the current object

Returns:

A duplciate copy of the current object

toString

public String toString()

Returns the string representation of the object.
