Class NodeDefParser

java.lang.Object
  edu.cmu.emulator.world.NodeDefParser

public class NodeDefParser
extends Object

The parser for parsing the NodeDef tag in the config file. After parsing the tag and its child nodes, this class creates an array of EmuNode objects and populates them based on the information extracted from the tags.

Method Detail

parseUserDef

public EmuNode[] parseUserDef(EmuNode[] emuNodes,
                              Element nodeDef)

This method parses the NodeDef contained in the user's config file. It is assumed that the NodeDef in the emulab config file has already been parsed and the list of emuNodes has been created.

parse

public EmuNode[] parse(Element nodeDef)

This method takes as input the DOM element representing the NodeDef tag and parses through its subtree. Also performs error checking to see if all tags are defined properly, and generates RunTimeException if the definition of a reqiured tag is missing.

Parameters:

nodeDef - The DOM element which represents the NodeDef tag subtree.

Returns:

The array of EmuNode object instances.

parseWiredNICDef

private String parseWiredNICDef(Element node)

parseNICDef

private EmuNIC[] parseNICDef(EmuNode emuNode,
                             Element node)

parseAntennaDef

private Antenna[] parseAntennaDef(EmuNIC emuNIC,
                                  Element nic)

print

public void print()

This method prints the data extracted from the NodeDef tag.
