[Geotools-devel] [jira] (GEOT-4191) Java 7 try-with-resource compatibility

Tue, 03 Jul 2012 03:11:08 -0700

Issue Type: Improvement Improvement
Affects Versions: 8.0-RC3
Assignee: Jody Garnett
Components: api
Created: 03/Jul/12 5:09 AM
Description:

reading into the Java 7 pipeline and Juno support for try-with-resource I am even more convinced that this is a necissary change for GeoTools 9.x.

Reading:

I will prepare a change request; it amounts to:

interface FeatureIterator< F extends Feature> implements Closable {
   public void close() throws IOException;
}

It allows the following:



Java 7: try-with-resource




try (FeatureIterator iterator = feastureSource.getFeatures()){
     while( iterator.hasNext() ){
           Feature f = iterator.next();
           System.out.println( f.getIdentifier() );
     }
}




This would finally let us recover for the darn for-each loop. FeatureReader and FeatureWriter should also implement closable.



Java 6: close() would throw IOException




FeatureIterator iterator = featureSource.getFeatures();
try {
     while( iterator.hasNext() ){
           Feature f = iterator.next();
           System.out.println( f.getIdentifier() );
     }    
}
finally {
    if( iterator != null ) iteator.close();
}
// IOException can be thrown from the above
