Stuart Smith updated MAHOUT-948:
--------------------------------
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>)

> Key: MAHOUT-948
> URL: https://issues.apache.org/jira/browse/MAHOUT-948
> Project: Mahout
> Issue Type: Improvement
> Components: Integration
> Environment: I just pulled the latest from SVN today (01/17/2012)
> Reporter: Stuart Smith
> Priority: Trivial
> Labels: patch
> Attachments: MapBackedARFFModel.java
>
> Original Estimate: 0h
> Remaining Estimate: 0h

> 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>
