void visit(int version, int access, java.lang.String name, java.lang.String superName, java.lang.String[] interfaces, java.lang.String sourceFile)
version
- the class version.access
- the class's access flags (see Constants
). This
parameter also indicates if the class is deprecated.name
- the internal name of the class (see getInternalName
).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 java.lang.Object
class.interfaces
- the internal names of the class's interfaces (see getInternalName
). May be null.sourceFile
- the name of the source file from which this class was
compiled. May be null.void visitInnerClass(java.lang.String name, java.lang.String outerName, java.lang.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.void visitField(int access, java.lang.String name, java.lang.String desc, java.lang.Object value, Attribute attrs)
access
- the field's access flags (see Constants
). This
parameter also indicates if the field is synthetic and/or deprecated.name
- the field's name.desc
- the field's descriptor (see Type
).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.attrs
- the non standard method attributes, linked together by their
next field. May be null.CodeVisitor visitMethod(int access, java.lang.String name, java.lang.String desc, java.lang.String[] exceptions, Attribute attrs)
CodeVisitor
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 Constants
). This
parameter also indicates if the method is synthetic and/or deprecated.name
- the method's name.desc
- the method's descriptor (see Type
).exceptions
- the internal names of the method's exception
classes (see getInternalName
). May be
null.attrs
- the non standard method attributes, linked together by their
next field. May be null.

- a non standard class attribute. Must not be null.void visitEnd()
