public class LocalVariableTable
extends Attribute
This class is derived from Attribute and represents colection of local variables in a method. This attribute is used by the Code attribute.

Version:
970922
Author:
M. Dahm
See Also:
Code, LocalVariable

Constructor Index

 o LocalVariableTable()
Empty constructor, all attributes have to be defined via `setXXX' methods.
 o LocalVariableTable(LocalVariableTable)
Initialize from another object.
 o LocalVariableTable(short, int, LocalVariable[], ConstantPool)

Method Index

 o accept(Visitor)
Called by objects that are traversing the nodes of the tree implicitely defined by the contents of a Java class.
 o dump(DataOutputStream)
Dump local variable table attribute to file stream in binary format.
 o getConstantPool()
 o getLocalVariableTable()
 o setConstantPool(ConstantPool)
 o setLocalVariableTable(LocalVariable[])
 o toString()

Constructors

 o LocalVariableTable
 public LocalVariableTable()
Empty constructor, all attributes have to be defined via `setXXX' methods. Use at your own risk.

 o LocalVariableTable
 public LocalVariableTable(LocalVariableTable c)
Initialize from another object. Note that both objects use the same references (shallow copy). Use clone() for a physical copy.

 o LocalVariableTable
 public LocalVariableTable(short name_index,
                           int length,
                           LocalVariable local_variable_table[],
                           ConstantPool constant_pool)
Parameters:
name_index - Index in constant pool
length - Content length in bytes
local_variable_table - Table of local variables
constant_pool - Array of constants

Methods

 o 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
Overrides:
accept in class Attribute
 o dump
 public final void dump(DataOutputStream file) throws IOException
Dump local variable table attribute to file stream in binary format.

Parameters:
file - Output file stream
Overrides:
dump in class Attribute
 o getConstantPool
 public final ConstantPool getConstantPool()
Returns:
Constant pool used by this object.
See Also:
ConstantPool
 o getLocalVariableTable
 public final LocalVariable[] getLocalVariableTable()
Returns:
Array of local variables of method.
 o setConstantPool
 public final void setConstantPool(ConstantPool constant_pool)
Parameters:
constant_pool - Constant pool to be used for this object.
See Also:
ConstantPool
 o setLocalVariableTable
 public final void setLocalVariableTable(LocalVariable local_variable_table[])
 o toString
 public final String toString()
Returns:
String representation.
Overrides:
toString in class Object
