create TableModel and populate jTable dynamically
- by Julia
Hi all!
I want to store the results of reading lucene index into jTable, so that I can make it sortable by different columns. From index I am reading terms with different measures of their frequencies.
Table columns are these :
[string term][int absFrequency][int docFrequency][double invFrequency]
So i in AbstractTableModel I can define column names, but i dont know how to get the Object[][]data with results from the following method:
public static void FrequencyMap(Directory indexDir) throws Exception
{
List<Object>redoviLista = new ArrayList<Object>();
//final Map<String,TermRow> map = new TreeMap<String,TermRow>();
List<String>termList = new ArrayList<String>();
IndexReader iReader = IndexReader.open(indexDir);
FilterIndexReader fReader = new FilterIndexReader(iReader);
int numOfDocs = fReader.numDocs();
TermEnum terms = fReader.terms();
while (terms.next()){
Term term = terms.term();
String termText = term.text();
termList.add(termText);
//Calculating the frequencies
int df = iReader.docFreq(term);
double idf = 0.0F;
idf = Math.log10((double) numOfDocs / df);
double tfidf = (df*idf);
//Here comes important part
Object oneTableRow[] = {termText, df, idf, tfidf};
redoviLista.add(jedanRed); // So i thaught to store them into list, and then later to copy into table, but didnt manage
}
iReader.close();
// So I need something like this, and i Neeed this array to be stored out of this method
Object[][]data = new Object[redoviLista.size()][];
for (int i = 0; i < data.length; i++) {
data[i][0] = redoviLista.get(i);
}
So I am kindda stuck here to proceed to implement AbstractTableModel and populate and display this table .... :/
Please help!
