Description copied from interface: ClassVisitor

Visits the header of the class.

Parameters:: 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.

visitSource

public void visitSource(String source,
                        String debug)

Description copied from interface: ClassVisitor

Visits the source of the class.

Specified by:: visitSource in interface ClassVisitor

Parameters:: 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.

visitOuterClass

Description copied from interface: ClassVisitor

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

Specified by:: visitOuterClass in interface 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.; 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.

May be null for anonymous inner classes.; access - the access flags of the inner class as originally declared in the enclosing class.

visitField

public FieldVisitor visitField(int access,
