Class GMLNode

java.lang.Object
  cytoscape.data.readers.GMLNode

All Implemented Interfaces:

Comparator

public class GMLNode
extends Object
implements Comparator

This class represents a GMLNode. A GMLNode can be either a GML terminal, or contain a mapping from string keys to other GMLNodes

Field Summary

boolean

terminal True if this node is a terminal.

Constructor Summary

GMLNode()
This constructor creates a non-terminal GMLNode.

GMLNode(String string_value)
This constructor create a terminal GMLNode.

Method Summary

void	addMapping(String key, GMLNode node) Add a mapping from key to node
int	compare(Object o1, Object o2)
Double	doubleValue() Get the value of this node as a Double
Vector	getMapping(String key) Return the data mapped by this key
Integer	integerValue() Get the value of this node as an Integer
String	stringValue() Get the value of this node as a String
String	toString() Return the string representation of this GMLNode.

Field Detail

terminal

public boolean terminal

True if this node is a terminal. (A terminal node is one that just contains a piece of data (string,double,int) and not further mapping to GMLNodes

Constructor Detail

GMLNode

public GMLNode(String string_value)

This constructor create a terminal GMLNode.

Parameters:

string_value - The terminal value of the GMLNode

GMLNode

public GMLNode()

This constructor creates a non-terminal GMLNode. The mapping is initially empty. Mappings are added using addMapping

Method Detail

toString

public String toString()

Return the string representation of this GMLNode. This will recursively print out all mapped subGMLNodes if present.

Overrides:

toString in class Object

compare

public int compare(Object o1,
                   Object o2)

Specified by:

compare in interface Comparator

doubleValue

public Double doubleValue()

Get the value of this node as a Double

Returns:

The value of this node as a double

Throws:

RuntimeException - if the value of this node cannot be interpreted as a Double

integerValue

public Integer integerValue()

Get the value of this node as an Integer

Returns:

The value of this node as an Integer

Throws:

RuntimeException - if the value of this node cannot be interpreted as an Integer

stringValue

public String stringValue()

Get the value of this node as a String

Returns:

The value of this node as a String

addMapping

public void addMapping(String key,
                       GMLNode node)

Add a mapping from key to node

Parameters:

key - The key for the mapping

node - The node which will map to the key

getMapping

public Vector getMapping(String key)

Return the data mapped by this key

Parameters:

key - The key to look up

Returns:

A vector of GMLNodes (may be null)
