Class LocalVariable
- public final class LocalVariable
- implements Constants
This class represents a local variable within a method. It contains its
scope, name, signature and index on the method's frame.

LocalVariable
public LocalVariable()
- Empty constructor, all attributes have to be defined via `setXXX'
methods. Use at your own risk.
LocalVariable
public LocalVariable(LocalVariable c)
- Initialize from another object. Note that both objects use the same
references (shallow copy). Use clone() for a physical copy.
LocalVariable
LocalVariable(DataInputStream file, ConstantPool constant_pool)
throws java.io.IOException
- Construct object from file stream.
- Parameters:
- file - Input stream
- throw IOException
LocalVariable
public LocalVariable(int start_pc, int length, int name_index, int signature_index, int slot, ConstantPool constant_pool)
- Parameters:
- start_pc - Range in which the variable
- length - ... is valid
- name_index - Index in constant pool of variable name
- signature_index - Index of variable's signature
- slot - Variable is `slot'th local variable on the method's frame
- constant_pool - Array of constants
accept
public void accept(Visitor v)
- Called by objects that are traversing the nodes of the tree implicitely
defined by the contents of a Java class. I.e., the hierarchy of methods,
fields, attributes, etc. spawns a tree of objects.
- Parameters:
- v - Visitor object
dump
public final void dump(DataOutputStream file)
throws java.io.IOException
- Dump local variable to file stream in binary format.
- Parameters:
- file - Output file stream
- throw IOException

getSlot
public final int getSlot()
- Returns: Variable is `getSlot()'th local variable on this method's frame.
getStartPC
public final int getStartPC()
- Returns: Start of range where he variable is valid

setSlot
public final void setSlot(int slot)
- Parameters:
- slot.
setStartPC
public final void setStartPC(int start_pc)
- Parameters:
