All Implemented Interfaces:

java.lang.Cloneable, Node, Constants
```
public final class LocalVariable
extends java.lang.Object
implements java.lang.Cloneable, Node, Constants
```
This class represents a local variable within a method. It contains its scope, name, signature and index on the method's frame. It is used both to represent an element of the LocalVariableTable as well as an element of the LocalVariableTypeTable. The nomenclature used here may be a bit confusing; while the two items have the same layout in a class file, a LocalVariableTable attribute contains a descriptor_index, not a signatureIndex. The LocalVariableTypeTable attribute does have a signatureIndex.
