Class Node

java.lang.Object
  com.reades.mapthing.Node

All Implemented Interfaces:

Serializable

public class Node
extends Object
implements Serializable

A simple node class that holds references to a position and an identifier. You would usually want to extend this class to do something more clever, but this is also used internally to hold the transformed coordinates within a Polygons/Lines/Points object.

The idea here is that we take our complex geographic coordinates from the data source and turn them into simple objects that are easy to draw in Processing as this will be faster and it will also be simpler to move them around and do things like zoom and pan.

Method Summary

int	getId() Get the (preferably) unique identifier
String	getName() Get the (preferably) unique name
double	getValue() A better way to get a value that is distinct from some z-value such as an altitude.
float	getX() The x-position of the node
float	getY() The y-position of the node
float	getZ() The z-position of the node -- you can overload this as the value of the node if you like since it doesn't have to be a geographical z-axis.

Method Detail

getId

public int getId()

Get the (preferably) unique identifier

Returns:

A (preferably) unique identifying integer

getName

public String getName()

Get the (preferably) unique name

Returns:

A (preferably) unique identifying name

getX

public float getX()

The x-position of the node

Returns:

A float representing the node's x-position

getY

public float getY()

The y-position of the node

Returns:

A float representing the node's y-position

getZ

public float getZ()

The z-position of the node -- you can overload this as the value of the node if you like since it doesn't have to be a geographical z-axis.

Returns:

A float representing the node's z-position or value

getValue

public double getValue()

A better way to get a value that is distinct from some z-value such as an altitude.

Returns:

A double representing the node's 'value' on an arbitrary scale
