IterTres15Java

There isn't a way to get an iterator for the TRE fields in the 1.5 release. However, you can get/set field values. Below is an example that illustrates setting the FILCMT field in a JITCID TRE. (i_3228c.ntf is an example NITF file that contains a JITCID TRE in the FileHeader).

Extensions extendedSection = record.getHeader().getExtendedSection();
Iterable<TRE> tres = extendedSection.getTREsByName("JITCID");
if (tres.iterator().hasNext())
{
    final TRE tre = tres.iterator().next();
    try
    {
        final Field field = tre.getField("FILCMT");
        // let's go ahead and just re-set the field
        field.setData("My comment");
    }
    catch (NoSuchFieldException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
