vogella.de

Create a package "de.vogella.jface.tableviewer.model".

Create the following class "Person". This class contains the first name, last name, gender and married status for a person and represents the data model for this example.

			
package de.vogella.jface.tableviewer.model;

import java.beans.PropertyChangeListener;
import java.beans.PropertyChangeSupport;

public class Person {
	private String firstName;
	private String lastName;
	private boolean married;
	private String gender;
	private Integer age;
	private PropertyChangeSupport propertyChangeSupport = new PropertyChangeSupport(
			this);

	public Person() {
	}

	public Person(String firstName, String lastName, String gender,
			boolean married) {
		super();
		this.firstName = firstName;
		this.lastName = lastName;
		this.gender = gender;
		this.married = married;
	}

	public void addPropertyChangeListener(String propertyName,
			PropertyChangeListener listener) {
		propertyChangeSupport.addPropertyChangeListener(propertyName, listener);
	}

	public void removePropertyChangeListener(PropertyChangeListener listener) {
		propertyChangeSupport.removePropertyChangeListener(listener);
	}

	public String getFirstName() {
		return firstName;
	}

	public String getGender() {
		return gender;
	}

	public String getLastName() {
		return lastName;
	}

	public boolean isMarried() {
		return married;
	}

	public void setFirstName(String firstName) {
		propertyChangeSupport.firePropertyChange("firstName", this.firstName,
				this.firstName = firstName);
	}

	public void setGender(String gender) {
		propertyChangeSupport.firePropertyChange("gender", this.gender,
				this.gender = gender);
	}

	public void setLastName(String lastName) {
		propertyChangeSupport.firePropertyChange("lastName", this.lastName,
				this.lastName = lastName);
	}

	public void setMarried(boolean isMarried) {
		propertyChangeSupport.firePropertyChange("married", this.married,
				this.married = isMarried);
	}

	public Integer getAge() {
		return age;
	}

	public void setAge(Integer age) {
		propertyChangeSupport.firePropertyChange("age", this.age,
				this.age = age);
	}

	@Override
	public String toString() {
		return firstName + " " + lastName;
	}

}
		

Now create a class, called "ModelProvider". This class will be providing the collection of persons. This class is defined as a Singleton (see The Singleton Pattern for details).

			
package de.vogella.jface.tableviewer.model;

import java.util.ArrayList;
import java.util.List;

public class ModelProvider {

	private static ModelProvider content;
	private List<Person> persons;

	private ModelProvider() {
		persons = new ArrayList<Person>();
		// Image here some fancy database access to read the persons and to
		// put them into the model
		Person person;
		person = new Person("Rainer", "Zufall", "male", true);
		persons.add(person);
		person = new Person("Rainer", "Babbel", "male", true);
		persons.add(person);
		person = new Person("Marie", "Darms", "female", false);
		persons.add(person);
		person = new Person("Holger", "Adams", "male", true);
		persons.add(person);
		person = new Person("Juliane", "Adams", "female", true);
		persons.add(person);

	}

	public static synchronized ModelProvider getInstance() {
		if (content != null) {
			return content;
		}
		content = new ModelProvider();
		return content;
	}

	public List<Person> getPersons() {
		return persons;
	}

}
