Method Summary

protected void	finalize() For debugging
void	initialize(java.util.Hashtable router_table, java.util.Hashtable host_table, java.util.Hashtable link_table) Initialize this Topology Parser.
void	load(java.lang.String filename) Loads file into a char array and ignores commented lines
void	loadElement(java.lang.String line) Public wrapper to parse(line).
private void	parse(java.lang.String line) Parses a single line and creates network objects accordingly.
boolean	prePlugout(java.lang.Object replacement) We don't need to do anything special for cleanup, but we cannot be removed without replacement.

routers

protected java.util.Hashtable routers

hosts

protected java.util.Hashtable hosts

links

protected java.util.Hashtable links

sim

protected Simulator sim

nattedNodes

private java.util.Hashtable nattedNodes

nattedRouters

private java.util.Hashtable nattedRouters

current_line

protected transient int current_line

OTTER_TEMP_FILE

public static final java.lang.String OTTER_TEMP_FILE

See Also:

Constant Field Values

next_link_id

protected int next_link_id

The ID of the next link to create. This needs to be shared between topology parsers so that new links can be added without destroying links in the simulator's hash table after a new topology parser is plugged in.

Method Detail

initialize

public void initialize(java.util.Hashtable router_table,
                       java.util.Hashtable host_table,
                       java.util.Hashtable link_table)

Initialize this Topology Parser.

Specified by:

load

public void load(java.lang.String filename)

Loads file into a char array and ignores commented lines

Specified by:

load in class TopologyParser

Parameters:

filename - name loaded file

loadElement

public void loadElement(java.lang.String line)

Public wrapper to parse(line).

Specified by:

loadElement in class TopologyParser

parse

private void parse(java.lang.String line)

Parses a single line and creates network objects accordingly.

Parameters:

line - parsed line

save

public void save(java.lang.String filename)

Saves the current topology to a file.

Specified by:

save in class TopologyParser

Parameters:

filename - name to save topology to

view

public void view()

Description copied from class: TopologyParser

View the current topology.

Specified by:

view in class TopologyParser

view

public void view(boolean showIPAddresses)

View the current topology using Otter (writing out to a temp file).

Specified by:

view in class TopologyParser

Parameters:

showIPAddresses - whether or not to show the IP addresses of the nodes

prePlugout

public boolean prePlugout(java.lang.Object replacement)

We don't need to do anything special for cleanup, but we cannot be removed without replacement.

Specified by:

prePlugout in interface Pluggable

Returns:

if this object can now be removed (was the operation sucessful)

finalize

protected void finalize()
