KMLCoordinateTokenizer (NASA WorldWind)

java.lang.Object
- gov.nasa.worldwind.ogc.kml.KMLCoordinateTokenizer

```
public class KMLCoordinateTokenizer
extends java.lang.Object
```
Tokenizer to read coordinate values from KML coordinate string. The components of each coordinate tuple are separated by commas, as defined by the KML spec, coordinate tuples are comma separated, and each tuple is separated from the surrounding tuples by whitespace. For example:
```
 -18.3,23.5,0 -19.3,23.4,1 -20.0,23.5,2
 
```
However, some KML files do not follow the spec and embed white space within the coordinate tuples. This tokenizer attempts to be lenient with whitespace handling. If a tuple ends with a comma, the tokenizer considers the next token in the input stream to be part of the same coordinate, not the start of a new coordinate.
For example:
```
 -18.3,23.56,9     34.9, 56.0, 2     56.9, 19     90.0,23.9,44
 
```
Will be tokenized to four coordinates: (23.56, -18.3, 9), (56.0, 34.9, 2), (56.9, 19, 0), and (90, 23.9, 44).
The tokenizer also handles coordinate strings with no embedded white space. For example:
```
 -18.3,23.56,9,34.9,56.0,2
 
```
Will be tokenized to two coordinates: (23.56, -18.3, 9), (56.0, 34.9, 2)

public KMLCoordinateTokenizer(java.lang.String s)
```
    Create a tokenizer to read coordinates from a string.
    
    Parameters:
    
    s - String to read from.
- Method Detail
  - hasMoreTokens
```
public boolean hasMoreTokens()
```
    Are there more coordinates to read?
    
    Returns:
    
    True if there are more coordinates to read from the string.
  - nextPosition
```
public Position nextPosition()
                      throws java.lang.NumberFormatException
```
    Read the next Position from the coordinate string.
    
    Returns:
    
    Next Position, or null if an error occurs while parsing the position (number format exception, etc).
    
    Throws:
    
    java.lang.NumberFormatException - if the coordinates cannot be parsed to a number.
