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

Description copied from interface: ClassVisitor

Visits the header of the class.

Specified by:

visit in interface ClassVisitor

Overrides:

visit in class ClassAdapter

Parameters:

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.

visitEnd

public void visitEnd()

Description copied from interface: ClassVisitor

Visits the end of the class. This method, which is the last one to be called, is used to inform the visitor that all the fields and methods of the class have been visited.

Specified by:

visitEnd in interface ClassVisitor

Overrides:

visitEnd in class ClassAdapter

visitField

public void visitField(int access,
                       java.lang.String name,
                       java.lang.String desc,
                       java.lang.Object value,
                       Attribute attrs)

Description copied from interface: ClassVisitor

Visits a field of the class.

Specified by:

visitField in interface ClassVisitor

Overrides:

visitField in class ClassAdapter

Parameters:

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. 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.

visitMethod

public CodeVisitor visitMethod(int access,
                               java.lang.String name,
                               java.lang.String desc,
                               java.lang.String[] exceptions,
                               Attribute attrs)

Description copied from interface: ClassVisitor

Visits a method of the class. This method must return a new CodeVisitor instance (or null) each time it is called, i.e., it should not return a previously returned visitor.

Specified by:

visitMethod in interface ClassVisitor

Overrides:

visitMethod in class ClassAdapter

Parameters:

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.

Returns:

an object to visit the byte code of the method, or null if this class visitor is not interested in visiting the code of this method.

visitAttribute

public void visitAttribute(Attribute attrs)

Description copied from interface: ClassVisitor

Visits a non standard attribute of the class. This method must visit only the first attribute in the given attribute list.

Specified by:

visitAttribute in interface ClassVisitor

Overrides:

visitAttribute in class ClassAdapter

Parameters:

attrs - a non standard class attribute. Must not be null.
