Interface AnnotationVisitor
- AnnotationNode, ASMifierAnnotationVisitor, CheckAnnotationAdapter, EmptyVisitor, RemappingAnnotationAdapter, SAXAnnotationAdapter, TraceAnnotationVisitor
public interface AnnotationVisitor
A visitor to visit a Java annotation. The methods of this interface must be
called in the following order: (visit | visitEnum |
visitAnnotation | visitArray)* visitEnd.
- Eric Bruneton
- Eugene Kuleshov
void | visit(String name, Object value) - Visits a primitive value of the annotation.
|
AnnotationVisitor | visitAnnotation(String name, String desc) - Visits a nested annotation value of the annotation.
|
AnnotationVisitor | visitArray(String name) - Visits an array value of the annotation.
|
void | visitEnd() - Visits the end of the annotation.
|
void | visitEnum(String name, String desc, String value) - Visits an enumeration value of the annotation.

visit
public void visit(String name,
Object value)
Visits a primitive value of the annotation.
name
- the value name.value
- the actual value, whose type must be Byte
,
Boolean
, Character
, Short
,
Integer
, Long
, Float
, Double
,
String
or Type
. This value can also be an array
of byte, boolean, short, char, int, long, float or double values
(this is equivalent to using visitArray
and
visiting each array element in turn, but is more convenient).
visitAnnotation
public AnnotationVisitor visitAnnotation(String name,
String desc)
Visits a nested annotation value of the annotation.
name
- the value name.desc
- the class descriptor of the nested annotation class.
- a visitor to visit the actual nested annotation value, or
null if this visitor is not interested in visiting
this nested annotation. The nested annotation value must be
fully visited before calling other methods on this annotation
visitor.
visitArray
public AnnotationVisitor visitArray(String name)
Visits an array value of the annotation. Note that arrays of primitive
types (such as byte, boolean, short, char, int, long, float or double)
can be passed as value to
visit
. This is what
ClassReader
does.
- a visitor to visit the actual array value elements, or
null if this visitor is not interested in visiting
these values. The 'name' parameters passed to the methods of this
visitor are ignored. All the array values must be visited
before calling other methods on this annotation visitor.
visitEnd
public void visitEnd()
Visits the end of the annotation.
visitEnum
public void visitEnum(String name,
String desc,
String value)
Visits an enumeration value of the annotation.
name
- the value name.desc
- the class descriptor of the enumeration class.value
- the actual enumeration value.
