Hi all... I need to search an AreaShapeLayer's dbf file. I've tried the
following:
However.. I get a NullPointerException whennever I tried to access any
record related methods like getRecord(int i) or even itr.next() on the
iterator from getRecords. I've chcked over and over.. the "model" is not
null either. The app successfully prints out the number of records.
public static void search(ShapeLayer sLayer, String query, int column){
Properties layerProps = sLayer.getProperties(null);
String prefix = sLayer.getPropertyPrefix() + ".";
String dbfFileLocation = layerProps.getProperty(prefix +
"shapeFile");
dbfFileLocation = dbfFileLocation.replaceAll(".shp", ".dbf");
// <-- this is a hack... we can't access the dbfFile property... openmap
deletes it on shp layer load... dunno y
// we assume that the dbf file has the same name
DbfTableModel model = DbfFile.getDbfTableModel(dbfFileLocation);
System.out.println(model.getColumnCount() + " columns");
if(model != null){
Iterator itr = model.getRecords();
while(itr.hasNext()){
Object obj = itr.next();
}
}
}
