An example * of how to use this class is: * *
* TableColumn<Person,String> firstNameCol = new TableColumn<Person,String>("First Name");
* firstNameCol.setCellValueFactory(new PropertyValueFactory<Person,String>("firstName"));
*
*
* In this example, the "firstName" string is used as a reference to an assumed
* firstNameProperty()
method in the Person
class type
* (which is the class type of the TableView
* {@link TableView#itemsProperty() items} list). Additionally, this method must
* return a {@link Property} instance. If a method meeting these requirements
* is found, then the {@link TableCell} is populated with this
* {@literal ObservableValueIf no method matching this pattern exists, there is fall-through support
* for attempting to call get<property>() or is<property>() (that is,
* getFirstName()
or isFirstName()
in the example
* above). If a method matching this pattern exists, the value returned from this method
* is wrapped in a {@link ReadOnlyObjectWrapper} and returned to the TableCell.
* However, in this situation, this means that the TableCell will not be able
* to observe the ObservableValue for changes (as is the case in the first
* approach above).
*
*
For reference (and as noted in the TableColumn * {@link TableColumn#cellValueFactory cell value factory} documentation), the * long form of the code above would be the following: * *
* TableColumn<Person,String> firstNameCol = new TableColumn<Person,String>("First Name");
* firstNameCol.setCellValueFactory(new Callback<CellDataFeatures<Person, String>, ObservableValue<String>>() {
* public ObservableValue<String> call(CellDataFeatures<Person, String> p) {
* // p.getValue() returns the Person instance for a particular TableView row
* return p.getValue().firstNameProperty();
* }
* });
* }
