This API returns the end of file status set by the most recent file operation. It can determine whether the last call to display.grid.readChanged() found more changed records.
Return Value
A boolean value is returned. True indicates no more changed records were found. False indicates a changed record was found.
Example
pjs.defineDisplay("display", "subfiled.json", { rrnFields: { sfl: 'RRN' } });
// Load subfile grid data here
display.ctl.execute(); // display control record
// Now process all subfile grid records changed by the user
display.sfl.readChanged();
while (!pjs.endOfData()) {
// Process changed subfile records here
display.sfl.readChanged();
}
