Methods Summary
public voidvisit(int version, int access, java.lang.String name, java.lang.String superName, java.lang.String[] interfaces, java.lang.String sourceFile)
Visits the header of the class.

param
version the class version.
param
access the class's access flags (see {@link Constants}). This parameter also indicates if the class is deprecated.
param
name the internal name of the class (see {@link Type#getInternalName() getInternalName}).
param
superName the internal of name of the super class (see {@link Type#getInternalName() getInternalName}). For interfaces, the super class is {@link Object}. May be null, but only for the {@link Object java.lang.Object} class.
param
interfaces the internal names of the class's interfaces (see {@link Type#getInternalName() getInternalName}). May be null.
param
sourceFile the name of the source file from which this class was compiled. May be null.

public voidvisitAttribute(Attribute attr)
Visits a non standard attribute of the class. This method must visit only the first attribute in the given attribute list.

param
attr a non standard class attribute. Must not be null.

public voidvisitEnd()
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.

public voidvisitField(int access, java.lang.String name, java.lang.String desc, java.lang.Object value, Attribute attrs)
Visits a field of the class.

param
access the field's access flags (see {@link Constants}). This parameter also indicates if the field is synthetic and/or deprecated.
param
name the field's name.
param
desc the field's descriptor (see {@link Type Type}).
param
value the field's initial value. This parameter, which may be null if the field does not have an initial value, must be an {@link java.lang.Integer Integer}, a {@link java.lang.Float Float}, a {@link java.lang.Long Long}, a {@link java.lang.Double Double} or a {@link String 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.
param
attrs the non standard method attributes, linked together by their next field. May be null.

public voidvisitInnerClass(java.lang.String name, java.lang.String outerName, java.lang.String innerName, int access)
Visits information about an inner class. This inner class is not necessarily a member of the class being visited.

param
name the internal name of an inner class (see {@link Type#getInternalName() getInternalName}).
param
outerName the internal name of the class to which the inner class belongs (see {@link Type#getInternalName() getInternalName}). May be null.
param
innerName the (simple) name of the inner class inside its enclosing class. May be null for anonymous inner classes.
param
access the access flags of the inner class as originally declared in the enclosing class.

public CodeVisitorvisitMethod(int access, java.lang.String name, java.lang.String desc, java.lang.String[] exceptions, Attribute attrs)
Visits a method of the class. This method must return a new {@link CodeVisitor CodeVisitor} instance (or null) each time it is called, i.e., it should not return a previously returned visitor.

param
access the method's access flags (see {@link Constants}). This parameter also indicates if the method is synthetic and/or deprecated.
param
name the method's name.
param
desc the method's descriptor (see {@link Type Type}).
param
exceptions the internal names of the method's exception classes (see {@link Type#getInternalName() getInternalName}). May be null.
param
attrs the non standard method attributes, linked together by their next field. May be null.
return
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.
