Basic Property Example 1

This is a simple property example. It demonstrates three properties:

• name: a simple read-write, non-bound string property
• phone: a simple read-write, bound string property
• friend: a read-write List of Person objects

package sample;
 
import com.javadude.annotation.Bean;
import com.javadude.annotation.Property;
import com.javadude.annotation.PropertyKind;
 
@Bean(properties={
    @Property(name="name"),
    @Property(name="phone", bound=true),
    @Property(name="friend", type=Person.class, kind=PropertyKind.LIST)
}) 
public class Person extends PersonGen {
}

will generate the following code. The following methods are created for each property:

name

• String getName()
• void setName(String value)

phone

• String getPhone()
• void setPhone(String value)

friend

• Person getFriend(int i)
• List

  <person>

  getFriends()
• boolean friendsContains(Person value)
• void addFriend(Person value)
• void addFriend(int i, Person value)
• void clearFriends()

Because at least one of the properties is bound, the following methods are generated:

• PropertyChangeSupport getPropertyChangeSupport()
• void addPropertyChangeListener(PropertyChangeListener listener)
• void addPropertyChangeListener(String propertyName, PropertyChangeListener listener)
• void removePropertyChangeListener(PropertyChangeListener listener)
• void removePropertyChangeListener(String propertyName, PropertyChangeListener listener)

A toString() method is generated that reports the values of all three properties.
