Hello all,
Having a problem using the example (taken from this glorious list) returning
a collection of features
for the current layer. Basically it always returns a collection of size 0.
Here is the method I'm using :
public FeatureCollection getFeaturesSelectedOnLayer ()
{
net.refractions.udig.project.internal.Map currentMap =
ApplicationGISInternal.getActiveMap();
Layer layer =
currentMap.getEditManagerInternal().getSelectedLayer();
Query query = new DefaultQuery(layer.getSchema().getTypeName(),
layer.getFilter(),new String[]{"the_geom"});
FeatureIterator featureIterator = null;
FeatureCollection features = null;
try{
IProgressMonitor monitor = new NullProgressMonitor();
FeatureSource featureSource =
layer.getResource(FeatureSource.class, monitor);
features = featureSource.getFeatures(query);
featureIterator = features.features();
aLogger.info("features selected are : " + features.size() +
"type
name is " + layer.getSchema().getTypeName() + "..is selectable? " +
layer.isSelectable());
while(featureIterator.hasNext() )
{
Feature feature = featureIterator.next();
aLogger.info("Feature selected is : " +
feature.getAttribute("the_geom").toString());
}
}
catch (Exception e)
{
e.printStackTrace();
}
finally
{
if (featureIterator != null)
{
featureIterator.close();
}
}
return features;
}
If I just call the getFeatures() method - without the query, all the
features on that layer are returned correctly. Any idea what I am doing
wrong?
Thanks again for taking the time to read this.
