  org.fest.reflect.beanproperty.PropertyName

public final class PropertyName
extends Object

Understands the name of a property to access using Bean Introspection.

The following is an example of proper usage of this class:

   // Retrieves the value of the property "name"
   String name = property("name").ofType(String.class).in(person).get();

   // Sets the value of the property "name" to "Yoda"
   property("name").ofType(String.class).in(person).set("Yoda");

   // Retrieves the value of the property "powers"
   List<String> powers = property("powers").ofType(new TypeRef<List<String>>() {}).in(jedi).get();

   // Sets the value of the property "powers"
   List<String> powers = new ArrayList<String>();
   powers.add("heal");
   property("powers").ofType(new TypeRef<List<String>>() {}).in(jedi).set(powers);

public static PropertyName startPropertyAccess(String name)

Creates a new PropertyName: the starting point of the fluent interface for accessing properties using Bean Introspection.

Parameters:

name - the name of the property to access using Bean Introspection.

Returns:

the created PropertyName.

Throws:

NullPointerException - if the given name is null.

IllegalArgumentException - if the given name is empty.

ofType

public <T> PropertyType<T> ofType(Class<T> type)

Sets the type of the property to access.

NullPointerException - if the given type is null.

ofType

public <T> PropertyTypeRef<T> ofType(TypeRef<T> type)

Sets the type reference of the property to access. This method reduces casting when the type of the property to access uses generics.

For example:

   List<String> powers = property("powers").ofType(new TypeRef<List<String>>() {}).in(jedi).get();
 

Type Parameters:

T - the generic type of the property type.

Parameters:

type - the type of the property to access.
