Class StaticFieldName

java.lang.Object
  org.fest.reflect.field.StaticFieldName

public final class StaticFieldName
extends Object

Understands the name of a static field to access using Java Reflection.

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

   // Retrieves the value of the static field "count"
   int count = staticField("count").ofType(int.class).in(Person.class).get();

   // Sets the value of the static field "count" to 3
   staticField("count").ofType(int.class).in(Person.class).set(3);

   // Retrieves the value of the static field "commonPowers"
   List<String> commmonPowers = staticField("commonPowers").ofType(new TypeRef<List<String>>() {}).in(Jedi.class).get();

   // Sets the value of the static field "commonPowers"
   List<String> commonPowers = new ArrayList<String>();
   commonPowers.add("jump");
   staticField("commonPowers").ofType(new TypeRef<List<String>>() {}).in(Jedi.class).set(commonPowers);

Method Detail

beginStaticFieldAccess

public static StaticFieldName beginStaticFieldAccess(String name)

Creates a new StaticFieldName: the starting point of the fluent interface for accessing static fields using Java Reflection.

Parameters:

name - the name of the field to access using Java Reflection.

Returns:

the created StaticFieldName.

Throws:

NullPointerException - if the given name is null.

IllegalArgumentException - if the given name is empty.

ofType

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

Sets the type of the field to access.

Type Parameters:

T - the generic type of the field type.

Parameters:

type - the type of the field to access.

Returns:

a recipient for the field type.

Throws:

NullPointerException - if the given type is null.

ofType

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

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

For example:

   List<String> commmonPowers = staticField("commonPowers").ofType(new TypeRef<List<String>>() {}).in(Jedi.class).get();
 

Type Parameters:

T - the generic type of the field type.

Parameters:

type - the type of the field to access.

Returns:

a recipient for the field type.

Throws:

NullPointerException - if the given type reference is null.
