public interface ClassVisitor
A visitor to visit a Java class. The methods of this interface must be called in the following order: visit [ visitSource ] [ visitOuterClass ] ( visitAnnotation | visitAttribute )* (visitInnerClass | visitField | visitMethod )* visitEnd.

void visit(int version, int access, String name, String signature, String superName, String[] interfaces)
version
- the class version.access
- the class's access flags (see Opcodes
). This
parameter also indicates if the class is deprecated.name
- the internal name of the class (see
getInternalName
).signature
- the signature of this class. May be null if the
class is not a generic one, and does not extend or implement generic
classes or interfaces.superName
- the internal of name of the super class (see
getInternalName
). For interfaces, the
super class is Object
. May be null, but only for the
Object
class.interfaces
- the internal names of the class's interfaces (see
getInternalName
). May be null.void visitSource(String source, String debug)
source
- the name of the source file from which the class was
compiled. May be null.debug
- additional debug information to compute the correspondance
between source and compiled elements of the class. May be
null.void visitOuterClass(String owner, String name, String desc)
owner
- internal name of the enclosing class of the class.name
- the name of the method that contains the class, or
null if the class is not enclosed in a method of its
enclosing class.desc
- the descriptor of the method that contains the class, or
null if the class is not enclosed in a method of its
enclosing class.AnnotationVisitor visitAnnotation(String desc, boolean visible)
desc
- the class descriptor of the annotation class.visible
- true if the annotation is visible at runtime.
void visitAttribute(Attribute attr)
attr
- an attribute.void visitInnerClass(String name, String outerName, String innerName, int access)
name
- the internal name of an inner class (see
getInternalName
).outerName
- the internal name of the class to which the inner class
belongs (see getInternalName
). May be
null.innerName
- the (simple) name of the inner class inside its enclosing
class. May be null for anonymous inner classes.access
- the access flags of the inner class as originally declared
in the enclosing class.FieldVisitor visitField(int access, String name, String desc, String signature, Object value)
access
- the field's access flags (see Opcodes
). This
parameter also indicates if the field is synthetic and/or deprecated.name
- the field's name.desc
- the field's descriptor (see Type
).signature
- the field's signature. May be null if the field's
type does not use generic types.value
- the field's initial value. This parameter, which may be
null if the field does not have an initial value, must be an
Integer
, a Float
, a Long
, a Double
or
a String
(for int, float, long
or String fields respectively). This parameter is only
used for static fields. Its value is ignored for non static
fields, which must be initialized through bytecode instructions in
constructors or methods.
MethodVisitor visitMethod(int access, String name, String desc, String signature, String[] exceptions)
MethodVisitor
instance (or null) each time it
is called, i.e., it should not return a previously returned visitor.
access
- the method's access flags (see Opcodes
). This
parameter also indicates if the method is synthetic and/or deprecated.name
- the method's name.desc
- the method's descriptor (see Type
).signature
- the method's signature. May be null if the method
parameters, return type and exceptions do not use generic types.exceptions
- the internal names of the method's exception
classes (see getInternalName
). May be
null.
void visitEnd()
