- the field to pull attributes frompublic Class<?> getDeclaringClass()
public String getName()
public Type getDeclaredType()
For example, assume the following class definition:
public class Foo { private String bar; private List<String> red; } Type listParameterizedType = new TypeToken<List<String>>() {}.getType();
This method would return String.class
for the bar
field and
listParameterizedType
for the red
field.
public Class<?> getDeclaredClass()
Class
object that was declared for this field.
For example, assume the following class definition:
public class Foo { private String bar; private List<String> red; }
This method would return String.class
for the bar
field and
List.class
for the red
field.
