Method Detail

compareTo

public int compareTo(Object o)

Compare to the passed object. Uses compare() from the underlying snmp-library

Specified by:

compareTo in interface Comparable

Parameters:

o - Object to compare with (Usually a ComparableSnmpObjectId)

Returns:

-1, if no SnmpObjectId passed in, the result of the underlying compare otherwise.

See Also:

SnmpObjectId.compare()

isLeaf

public boolean isLeaf()

This object is a leaf if the last part of the oid parts is a 0 (Zero)

Returns:

true if the oid ends in 0

removeLastPart

public ComparableSnmpObjectId removeLastPart()

Removes the last oid-component. Example .1.2.3.4.0 as input yields .1.2.3.4 as output

Returns:

an oid with the last part removed.

getNextArc

public ComparableSnmpObjectId getNextArc()

Build an oid where the second last component (after removing a .0 of a leaf) is increased by 1. The last component is removed, to the result actually forms the root of a subtree, that is adjacent to the subtree this object is in. Example .1.2.3.4.0 -> .1.2.4 Example .1.2.3.4.5 -> .1.2.4

Returns:
