Method Detail

toTagString

public java.lang.String toTagString()

To convert the object to a printable string tagged with Counter:

Overrides:

toTagString in class SnmpUnsignedInt

Returns:

string tagged with Counter:

toValue

public java.lang.Object toValue()

This method will give the SnmpCounter as Long object.

Overrides:

toValue in class SnmpUnsignedInt

Returns:

Long Object value.

Since:

AdventNet SNMP API 4 SP4 ( Release 4.0.4 )

getIncrement

public long getIncrement(SnmpCounter c)

Gets the (positive) increment of this Counter variable over another. Takes care of wraparound by adding the MAX counter value if negative.

getIncrement

public long getIncrement(long lastValue)

Gets the (positive) increment of this Counter variable over a long. Takes care of wraparound by adding the MAX counter value if negative.

encode

int encode(byte[] buff,
           int space)
     throws java.lang.ArrayIndexOutOfBoundsException

ASN encoder

Overrides:

encode in class SnmpUnsignedInt

Parameters:

buff - The buffer into which the value is to be encoded

space - The number of free bytes in the buffer

Returns:

The number of free bytes in the buffer

Throws:

java.lang.ArrayIndexOutOfBoundsException - When there is insufficient space in buffer
