(2c) optionally override createTableModel() to provide specify custom cell formatters / comparators. The following example sets both a formatter and a comparator for the "code" column:
...
(2d) implement populateTable() by adding to add rows to the supplied table model:
| Code Block | ||
|---|---|---|
| ||
@Override
protected void populateTable(TableModel tm, ObjectNode payload) {
// ...
// fake data for demonstration purposes...
List<Item> items = getItems();
for (Item item: items) {
populateRow(tm.addRow(), item);
}
}
private void populateRow(TableModel.Row row, Item item) {
row.cell(ID, item.id())
.cell(LABEL, item.label())
.cell(CODE, item.code());
} |
The example sample template uses fake data for demonstration purposes. A more realistic implementation would use one or more services to obtain the required data. For exampleThe device table, for example, has an implementation something like this:
| Code Block | ||
|---|---|---|
| ||
@Override
protected void populateTable(TableModel tm, ObjectNode payload) {
DeviceService ds = get(DeviceService.class);
MastershipService ms = get(MastershipService.class);
for (Device dev : ds.getDevices()) {
populateRow(tm.addRow(), dev, ds, ms);
}
}
private void populateRow(TableModel.Row row, Device dev,
DeviceService ds, MastershipService ms) {
DeviceId id = dev.id();
String protocol = dev.annotations().value(PROTOCOL);
row.cell(ID, id)
.cell(MFR, dev.manufacturer())
.cell(HW, dev.hwVersion())
.cell(SW, dev.swVersion())
.cell(PROTOCOL, protocol != null ? protocol : "")
.cell(NUM_PORTS, ds.getPorts(id).size())
.cell(MASTER_ID, ms.getMasterFor(id));
}
