    Comment: was deleted

(was: Eh, description didn't respect the code tags:
<code>
  public double getValue(String data, int idx) {
    ARFFType type = typeMap.get(idx);
    data = QUOTE_PATTERN.matcher(data).replaceAll("");
    data = data.trim();
    double result;
    if( type == null ) {
        throw new IllegalStateException( "Attribute type cannot be NULL, attribute index was: " + idx );
    }		
    switch (type) {
      case NUMERIC:
        result = processNumeric(data);
        break;
 </code>)

>             Project: Mahout
>          Issue Type: Improvement
>          Components: Integration
>         Environment: I just pulled the latest from SVN today (01/17/2012)
>            Reporter: Stuart Smith
>            Priority: Trivial

> MapBackedARFFModel throws an NPE when getValue is passed an idx for an attribute that does not exist.
> In short, this:
> <code>
>   public double getValue(String data, int idx) {
>     ARFFType type = typeMap.get(idx);
>     data = QUOTE_PATTERN.matcher(data).replaceAll("");
>     data = data.trim();
>     double result;
>     if( type == null ) {
> 	throw new IllegalStateException( "Attribute type cannot be NULL, attribute index was: " + idx );
>     }		
>     switch (type) {
>       case NUMERIC:
>         result = processNumeric(data);
> </code>
> Is better than this:
> <code>
>   public double getValue(String data, int idx) {
>     ARFFType type = typeMap.get(idx);
>     data = QUOTE_PATTERN.matcher(data).replaceAll("");
>     data = data.trim();
>     double result;
>    switch (type) {
>       case NUMERIC:
>         result = processNumeric(data);
>  </code>
