All Implemented Interfaces:

DeepCompare

public class LoggedNetworkTopology
extends Object
implements DeepCompare

A LoggedNetworkTopology represents a tree that in turn represents a hierarchy of hosts. The current version requires the tree to have all leaves at the same level. All of the public methods are simply accessors for the instance variables we want to write out in the JSON files.

deepCompare

public void deepCompare(DeepCompare comparand,
                        TreePath loc)
                 throws DeepInequalityException

Specified by:

deepCompare in interface DeepCompare

Parameters:

comparand - the other comparand that's being compared to me

loc - the path that got to me. In the root, myLocation is null. To process the scalar foo field of the root we will make a recursive call with a TreePath whose fieldName is "bar" and whose index is -1 and whose parent is null. To process the plural bar field of the root we will make a recursive call with a TreePath whose fieldName is "foo" and whose index is -1 and whose parent is also null.

Throws:

DeepInequalityException
