Modifier and Type | Method | Description |
---|---|---|
<T extends Annotation> |
getAnnotation(Class<T> annotation) |
Return the
T annotation object from this field if it exist; otherwise returns
null . |
Collection<Annotation> |
getAnnotations() |
Return the annotations that are present on this field.
|
Class<?> |
getDeclaredClass() |
Returns the
Class object that was declared for this field. |
Type |
getDeclaredType() |
For example, assume the following class definition:

- 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.
public <T extends Annotation> T getAnnotation(Class<T> annotation)
T
annotation object from this field if it exist; otherwise returns
null
.annotation
- the class of the annotation that will be retrievednull
public Collection<Annotation> getAnnotations()
public boolean hasModifier(int modifier)
true
if the field is defined with the modifier
.
This method is meant to be called as:
boolean hasPublicModifier = fieldAttribute.hasModifier(java.lang.reflect.Modifier.PUBLIC);
