Examples of com.vaadin.data.util.PropertyFormatter

com.vaadin.data.util.PropertyFormatter
Formatting proxy for a {@link Property}.
This class can be used to implement formatting for any type of Property datasources. The idea is to connect this as proxy between UI component and the original datasource.

For example
```
textfield.setPropertyDataSource(new PropertyFormatter(property) { public String format(Object value) { return ((Double) value).toString() + "000000000"; } public Object parse(String formattedValue) throws Exception { return Double.parseDouble(formattedValue); } });
```
adds formatter for Double-typed property that extends standard "1.0" notation with more zeroes.
@param T type of the underlying property (a PropertyFormatter is always a Property<String>) @deprecated As of 7.0, replaced by {@link Converter} @author Vaadin Ltd. @since 5.3.0

            public Field createField(Item item, Object propertyId,
                    Component uiContext) {
                AbstractField f = (AbstractField) DefaultFieldFactory.get()
                        .createField(item, propertyId, uiContext);
                if (propertyId.equals("age")) {
                    f.setPropertyDataSource(new PropertyFormatter() {


                        @Override
                        public Object parse(String formattedValue)
                                throws Exception {
                            String str = formattedValue.replaceAll("[^0-9.]",
