public class LocalVariableGen
extends Object
implements InstructionTargeter, Cloneable, Serializable
This class represents a local variable within a method. It contains its scope, name and type. The generated LocalVariable object
can be obtained with getLocalVariable which needs the instruction list and the constant pool as parameters.

LocalVariableGen
public LocalVariableGen(int index, String name, Type type, InstructionHandle start, InstructionHandle end) Generate a local variable that with index `index'. Note that double and long variables need two indexs. Index indices have to be provided by the user.- Parameter:
index- index of local variablename- its nametype- its typestart- from where the instruction is valid (null means from the start)end- until where the instruction is valid (null means to the end)

getLocalVariable
Get LocalVariable object. This relies on that the instruction list has already been dumped to byte code or or that the `setPositions' methods has been called for the instruction list. Note that for local variables whose scope end at the last instruction of the method's code, the JVM specification is ambiguous: both a start_pc+length ending at the last instruction and start_pc+length ending at first index beyond the end of the code are valid.- Parameter:
cp- constant poolil- instruction list (byte code) which this variable belongs to
