                  java.lang.String signature,
                  java.lang.String superName,
                  java.lang.String[] interfaces)

Description copied from class: ClassVisitor

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 Type.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 Type.getInternalName()). May be null.

visitModule

public ModuleVisitor visitModule(java.lang.String name,
                                 int access,

visitNestHost

public void visitNestHost(java.lang.String nestHost)

Description copied from class: ClassVisitor

Visits the nest host class of the class. A nest is a set of classes of the same package that share access to their private members. One of these classes, called the host, lists the other members of the nest, which in turn should link to the host of their nest. This method must be called only once and only if the visited class is a non-host member of a nest. A class is implicitly its own nest, so it's invalid to call this method with the visited class name as argument.

Overrides:

visitNestHost in class ClassVisitor

Parameters:

nestHost - the internal name of the host class of the nest.

visitOuterClass

public void visitOuterClass(java.lang.String owner,
                            java.lang.String name,
                            java.lang.String descriptor)

Description copied from class: ClassVisitor

Visits the enclosing class of the class. This method must be called only if the class has an enclosing class.

Overrides:

visitOuterClass in class ClassVisitor

Parameters:

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.

descriptor - the descriptor of the method that contains the class, or null if the class is not enclosed in a method of its enclosing class.

visitAnnotation

public AnnotationVisitor visitAnnotation(java.lang.String descriptor,
                                         boolean visible)

Description copied from class: ClassVisitor

Visits an annotation of the class.

Overrides:

visitAnnotation in class ClassVisitor

Parameters:

visible - true if the annotation is visible at runtime.

Returns:

a visitor to visit the annotation values, or null if this visitor is not interested in visiting this annotation.

visitTypeAnnotation

public AnnotationVisitor visitTypeAnnotation(int typeRef,
                                             TypePath typePath,
                                             java.lang.String descriptor,
                                             boolean visible)

Description copied from class: ClassVisitor

Visits an annotation on a type in the class signature.

Overrides:

visitTypeAnnotation in class ClassVisitor

Parameters:

typeRef - a reference to the annotated type. The sort of this type reference must be TypeReference.CLASS_TYPE_PARAMETER, TypeReference.CLASS_TYPE_PARAMETER_BOUND or TypeReference.CLASS_EXTENDS. See TypeReference.

typePath - the path to the annotated type argument, wildcard bound, array element type, or static inner type within 'typeRef'. May be null if the annotation targets 'typeRef' as a whole.

descriptor - the class descriptor of the annotation class.

visible - true if the annotation is visible at runtime.

Returns:

a visitor to visit the annotation values, or null if this visitor is not interested in visiting this annotation.

visitAttribute

public void visitAttribute(Attribute attribute)

Description copied from class: ClassVisitor

Visits a non standard attribute of the class.

Overrides:

visitAttribute in class ClassVisitor

Parameters:

attribute - an attribute.

visitNestMember

public void visitNestMember(java.lang.String nestMember)

Description copied from class: ClassVisitor

Visits a member of the nest. A nest is a set of classes of the same package that share access to their private members. One of these classes, called the host, lists the other members of the nest, which in turn should link to the host of their nest. This method must be called only if the visited class is the host of a nest. A nest host is implicitly a member of its own nest, so it's invalid to call this method with the visited class name as argument.

Parameters:

nestMember - the internal name of a nest member.

visitPermittedSubclass

                            int access)

Description copied from class: ClassVisitor

Visits information about an inner class. This inner class is not necessarily a member of the class being visited.

Overrides:

public RecordComponentVisitor visitRecordComponent(java.lang.String name,
                                                   java.lang.String descriptor,
                                                   java.lang.String signature)
