Class SNMPInteger

java.lang.Object
  snmp.SNMPObject
      snmp.SNMPInteger

Direct Known Subclasses:

SNMPCounter32, SNMPCounter64, SNMPGauge32, SNMPTimeTicks, SNMPUInteger32

public class SNMPInteger

extends SNMPObject

Defines an arbitrarily-sized integer value; there is no limit on size due to the use of Java.lang.BigInteger to store the value internally. For an indicator which "pegs" at its maximum value if initialized with a larger value, use SNMPGauge32; for a counter which wraps, use SNMPCounter32 or SNMPCounter64.

SNMPCounter32, SNMPGauge32, SNMPCounter64

Field Summary

protected byte	tag
protected java.math.BigInteger	value

Constructor Summary

	SNMPInteger() Initialize value to 0.
	SNMPInteger(java.math.BigInteger value)
protected	SNMPInteger(byte[] enc) Used to initialize from the BER encoding, usually received in a response from an SNMP device responding to an SNMPGetRequest.
	SNMPInteger(long value)

Method Summary

void	extractValueFromBEREncoding(byte[] enc) Used to extract a value from the BER encoding of the value.
protected byte[]	getBEREncoding() Returns the full BER encoding (type, length, value) of the SNMPInteger subclass.
java.lang.Object	getValue() Returns a java.lang.BigInteger object with the current value.
void	setValue(java.lang.Object newValue) Used to set the value with an instance of java.lang.Integer or java.lang.BigInteger.
java.lang.String	toString() Should return an appropriate human-readable representation of the stored value.
java.lang.String	toString(int radix)

Constructor Detail

SNMPInteger

public SNMPInteger()

Initialize value to 0.

SNMPInteger

public SNMPInteger(long value)

SNMPInteger

public SNMPInteger(java.math.BigInteger value)

SNMPInteger

protected SNMPInteger(byte[] enc)
               throws SNMPBadValueException

Used to initialize from the BER encoding, usually received in a response from an SNMP device responding to an SNMPGetRequest.

Throws:

SNMPBadValueException - Indicates an invalid BER encoding supplied. Shouldn't occur in normal operation, i.e., when valid responses are received from devices.

Method Detail

getValue

public java.lang.Object getValue()

Returns a java.lang.BigInteger object with the current value.

Specified by:

getValue in class SNMPObject

setValue

public void setValue(java.lang.Object newValue)
              throws SNMPBadValueException

Used to set the value with an instance of java.lang.Integer or java.lang.BigInteger.

Specified by:

setValue in class SNMPObject

Throws:

SNMPBadValueException - Indicates an incorrect object type supplied.

getBEREncoding

protected byte[] getBEREncoding()

Returns the full BER encoding (type, length, value) of the SNMPInteger subclass.

Specified by:

getBEREncoding in class SNMPObject

extractValueFromBEREncoding

public void extractValueFromBEREncoding(byte[] enc)
                                 throws SNMPBadValueException

Used to extract a value from the BER encoding of the value. Called in constructors for SNMPInteger subclasses.

Throws:

SNMPBadValueException - Indicates an invalid BER encoding supplied. Shouldn't occur in normal operation, i.e., when valid responses are received from devices.

toString

public java.lang.String toString()

Description copied from class: SNMPObject

Should return an appropriate human-readable representation of the stored value.

Specified by:

toString in class SNMPObject

toString

public java.lang.String toString(int radix)
