Class StaticFieldReflection

java.lang.Object
  r01f.reflection.fluent.StaticFieldReflection

public final class StaticFieldReflection
extends java.lang.Object

Static field reflection Usage example:

   // Retrieves the value of the static field "count"
   int count = Reflection.staticField("count").ofType(int.class).in(Person.class).get();
 
   // Sets the value of the static field "count" to 3
   Reflection.staticField("count").ofType(int.class).in(Person.class).set(3);
 
   // Retrieves the value of the static field "commonPowers"
   List commmonPowers = Reflection.staticField("commonPowers").ofType(new TypeRef>() {}).in(Jedi.class).get();
 
   // Sets the value of the static field "commonPowers"
   List commonPowers = new ArrayList();
   commonPowers.add("jump");
   Reflection.staticField("commonPowers").ofType(new TypeRef>() {}).in(Jedi.class).set(commonPowers);

Method Detail

startStaticFieldAccess

static StaticFieldReflection startStaticFieldAccess(java.lang.String fieldName)

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

Parameters:

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

Returns:

the created StaticFieldName.

Throws:

java.lang.NullPointerException - if the given name is null.

java.lang.IllegalArgumentException - if the given name is empty.

ofType

public <T> StaticFieldTypes.StaticFieldType<T> ofType(java.lang.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:

java.lang.NullPointerException - if the given type is null.

ofType

public <T> StaticFieldTypes.StaticFieldTypeGenerics<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. Usage example:

   List commmonPowers = Reflection.staticField("commonPowers").ofType(new TypeRef>() {}).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:

java.lang.NullPointerException - if the given type reference is null.
