java - SWT problems with saving data in the data base -

i trying make editable table using swt, while have trouble save dates modified in database using toplink:

  if (referenceviewid.equalsignorecase(tistableviewpart.id)) {         //todo yuchen : register , save objects in db         system.out.println("test");          final iviewpart viewpart = workbenchpage.findview(tistableviewpart.id);         final tistableviewpart vdv = (tistableviewpart) viewpart;          workingunitmasterdataimpl sessionuow = new workingunitmasterdataimpl();           object test = vdv.getlocalcomposite().gettableviewer().getelementat(1);         sessionuow.registerobject(test);          try {             sessionuow.commitandresume();         } catch (exception e) {             // todo auto-generated catch block             e.printstacktrace();         }   } 

by using

object test = vdv.getlocalcomposite().gettableviewer().getelementat(1); 

i can object of first colomne of table, use

sessionuow.registerobject(test); 

to save change. have idea whole table object in order register , commitresume? in advance.

if using tableviewer set contentprovider, assumed contentprovider holds elements table contains.

try access these elements through getelements() method in case content provider implements istructuredcontentprovider.

object[] elements = tableviever.getcontentprovider().getelements(); 

in case want register object changes, can in method setinput() ofthe contentprovider. indeed javadoc icontentprovider interface suggests method place registering changes.

if need access input @ moment, tableviewer object gives access table input through getinput() method:

object tableinput = tableviewer.getinput(); 

good luck!
