Class SnmpInt32

java.lang.Object
  org.opennms.protocols.snmp.SnmpInt32

All Implemented Interfaces:

Serializable, Cloneable, SnmpSyntax

public class SnmpInt32
extends Object
implements SnmpSyntax, Cloneable, Serializable

This class defines the SNMP 32-bit signed integer used by the SNMP SMI. This class also serves as a base class for any additional SNMP SMI types that exits now or may be defined in the future.

Constructor Detail

SnmpInt32

public SnmpInt32()

Default constructor. Builds a SnmpInt32 objeect with a value of zero.

SnmpInt32

public SnmpInt32(int value)

Constructs a SnmpInt32 object with the passed value.

Parameters:

value - The 32-bit signed integer value for the object.

SnmpInt32

public SnmpInt32(Integer value)

Constructs a SnmpInt32 object with the specified value.

Parameters:

value - An Integer object containing the 32-bte value.

SnmpInt32

public SnmpInt32(SnmpInt32 second)

Class copy constructor. Constructs a new object with the same value as the passed SnmpInt32 object.

Parameters:

second - The object to get the value from.

SnmpInt32

public SnmpInt32(String value)

Simple class constructor that attempts to parse the passed string into a valid integer value. If the String argument cannot be parse because it is either invalid or malformed then an exception is generated.

Parameters:

value - The integer value represented as a String

Throws:

NumberFormatException - Thrown if the passed value cannot be turned into a valid integer.

NullPointerException - Thrown if the passed string is a null reference.

Method Detail

getValue

public int getValue()

Used to access the internal 32-bit signed quantity.

Returns:

The 32-bit value

setValue

public void setValue(int value)

Used to set the 32-bit signed quantity

Parameters:

value - The new value for the object.

setValue

public void setValue(Integer value)

Used to set the 32-bit signed quantity

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 SnmpInt32

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 duplicate of the current object.

Specified by:

duplicate in interface SnmpSyntax

Returns:

A newly allocated duplicate object.

clone

public Object clone()

Returns a duplicate of the current object.

Overrides:

clone in class Object

Returns:

A newly allocated duplicate object.

toString

public String toString()

Returns the string representation of the object.

Overrides:

toString in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toInteger

public static Integer toInteger(SnmpInt32 val)
