protected final int api The ASM API version implemented by this visitor.
protected AnnotationVisitor av The annotation visitor to which this visitor must delegate method calls.
Public Constructors
AnnotationVisitor(int api)
Constructs a new AnnotationVisitor.
AnnotationVisitor(int api, AnnotationVisitor av)
Constructs a new AnnotationVisitor.
Public Methods
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)

Fields

protected final int api

The ASM API version implemented by this visitor. The value of this field must be one of ASM4.

protected AnnotationVisitor av

The annotation visitor to which this visitor must delegate method calls. May be null.

Public Constructors

public AnnotationVisitor (int api)

Constructs a new AnnotationVisitor.

Parameters
api the ASM API version implemented by this visitor. Must be one of ASM4.

public AnnotationVisitor (int api, AnnotationVisitor av)

Constructs a new AnnotationVisitor.

Parameters
api the ASM API version implemented by this visitor. Must be one of ASM4.
av the annotation visitor to which this visitor must delegate method calls. May be null.

Public Methods

public void visit (String name, Object value)

Visits a primitive value of the annotation.

Parameters
name the value name.
value the actual value, whose type must be Byte, Boolean, Character, Short, Integer , Long, Float, Double, String or Type or OBJECT or ARRAY sort. 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).

public AnnotationVisitor visitAnnotation (String name, String desc)

Visits a nested annotation value of the annotation.

Parameters
name the value name.
desc the class descriptor of the nested annotation class.
Returns
  • 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.

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.

Parameters
name the value name.
Returns
  • 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.

public void visitEnd ()

Visits the end of the annotation.

public void visitEnum (String name, String desc, String value)

Visits an enumeration value of the annotation.

Parameters
name the value name.
desc the class descriptor of the enumeration class.
value the actual enumeration value.
