ClassVisitor

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.public void visitSource(String source, String debug)
ClassVisitor
visitSource
in interface ClassVisitor
visitSource
in class ClassAdapter
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.public void visitOuterClass(String owner, String name, String desc)
ClassVisitor
visitOuterClass
in interface ClassVisitor
visitOuterClass
in class RemappingClassAdapter
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.public AnnotationVisitor visitAnnotation(String desc, boolean visible)
ClassVisitor
visitAnnotation
in interface ClassVisitor
visitAnnotation
in class RemappingClassAdapter
desc
- the class descriptor of the annotation class.visible
- true if the annotation is visible at runtime.
public void visitAttribute(Attribute attr)
ClassVisitor
visitAttribute
in interface ClassVisitor
visitAttribute
in class ClassAdapter
attr
- an attribute.public 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 for not member classes.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.public FieldVisitor visitField(int access, String name, String desc, String signature, Object value)
ClassVisitor
visitField
in interface ClassVisitor
visitField
in class RemappingClassAdapter
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.

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.
