Hi,
May be you can do something even more direct if you put the
featureCollection in an indexed list
ArrayList list = new ArrayList(featureCollection.getFeatures())
Then use the sample in JTable javadoc to build the model :
TableModel dataModel = new AbstractTableModel() {
public int getColumnCount() { return 10; } // FeatureSchema column
count
public int getRowCount() { return 10;} // list.size()
public Object getValueAt(int row, int col) { return new
Integer(row*col); } // list.get(row).getAttribute(col)
};
But if it is to be used in OpenJUMP, there is probably some benefits to
use AttributeTable

hey Peppe,
looks proper. performancewise i would no convert Lists to Arrays, but iterate
them directly. always keep in mind that datasets might get huge.

Hi Ede
I checked. It looks complicate for me to load a featurecollection into a JTable.
I found a quick way from Sextante gui, that I modified.
It generates a loop to fill all JTable records with feature values.
I post the code below.
public static TableModel setTableModelFromFeatureCollection(
FeatureCollection featureCollection) {
final DefaultTableModel model = new DefaultTableModel();
String[] fields;
int iCount;
iCount = featureCollection.getFeatures().size();
FeatureSchema schema = featureCollection.getFeatureSchema();
ArrayList<String> ar = new ArrayList<String>();
String name;
for (int j = 0; j < schema.getAttributeNames().size(); j++) {
name = schema.getAttributeName(j).toString();
ar.add(name);
}
fields = ar.toArray(new String[0]);
final String[][] data = new String[iCount][fields.length];
Feature[] featArray = featureCollection.getFeatures().toArray(
new Feature[0]);
for (int i = 0; i < featArray.length; i++) {
Feature feat = featArray[i];
for (int j = 0; j < schema.getAttributeCount(); j++) {
data[i][j] = feat.getAttribute(j).toString();
}
}
model.setDataVector(data, fields);
return model;
}

Peppe,
did you check the AttributeTable plugin? if there is, it will probably be
in use there?
