Class LocalVariableGen
- public final class LocalVariableGen
- implements Constants
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 slot, String name, ClassGenType type, InstructionHandle start, InstructionHandle end)
- Generate a local variable that with index `slot'. Note that double and long
variables need two slots. Slot indices have to be provided by the user.
- Parameters:
- slot - index of local variable
- name - its name
- type - its type
- start - from where the instruction is valid (null means from the start)
- end - until where the instruction is valid (null means to the end)
getEnd
public InstructionHandle getEnd()
getLocalVariable
public LocalVariable getLocalVariable(InstructionList il, ConstantPoolGen cp)
- Get LocalVariable object. If `start' is null it is set to the start of the method,
accordingly `end' points to the end of the instruction list if it was null.
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.
- Parameters:
- il - instruction list (byte code) which this variable belongs to
- cp - constant pool
