Modifier and Type | Method | Description |
---|---|---|
<T extends java.lang.annotation.Annotation> |
getAnnotation(java.lang.Class<T> annotation) |
Return the
T annotation object from this field if it exist; otherwise returns
null . |
java.util.Collection<java.lang.annotation.Annotation> |
getAnnotations() |
Return the annotations that are present on this field.
|
java.lang.Class<?> |
getDeclaredClass() |
Returns the
Class object that was declared for this field. |
java.lang.reflect.Type |
getDeclaredType() |
For example, assume the following class definition:
|
java.lang.Class<?> |
getDeclaringClass() |
|
java.lang.String |
getName() |
|
boolean |
hasModifier(int modifier) |
Returns
true if the field is defined with the modifier . |
public FieldAttributes(java.lang.reflect.Field f)
f
.f
- the field to pull attributes frompublic java.lang.Class<?> getDeclaringClass()
public java.lang.String getName()
public java.lang.reflect.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 java.lang.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 java.lang.annotation.Annotation> T getAnnotation(java.lang.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 java.util.Collection<java.lang.annotation.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);
