# Class LocalVariableTable

java.lang.Object
org.apache.bcel.classfile.Attribute
org.apache.bcel.classfile.LocalVariableTable

All Implemented Interfaces:
  `Cloneable, Iterable<LocalVariable>, Node`

public class LocalVariableTable extends Attribute implements Iterable<LocalVariable>
This class represents colection of local variables in a method. This attribute is contained in the Code attribute.

  Modifier and Type
  Method
  Description
  `void`
  `accept(Visitor v)`
  Called by objects that are traversing the nodes of the tree implicitly defined by the contents of a Java class.
  `Attribute`
  `copy(ConstantPool constantPool)`
  `final void`
  `dump(DataOutputStream file)`
  Dump local variable table attribute to file stream in binary format.
  `final LocalVariable`
  `getLocalVariable(int index)`
  Deprecated.
  since 5.2 because multiple variables can share the same slot, use getLocalVariable(int index, int pc) instead.

- ## Constructor Details

  - ### LocalVariableTable

    public LocalVariableTable(int nameIndex, int length, LocalVariable[] localVariableTable, ConstantPool constantPool)
    Parameters:
      `nameIndex` - Index in constant pool to 'LocalVariableTable'
      `length` - Content length in bytes
      `localVariableTable` - Table of local variables
      `constantPool` - Array of constants

  - ### LocalVariableTable

    public LocalVariableTable(LocalVariableTable c)
    Initialize from another object. Note that both objects use the same references (shallow copy). Use copy() for a physical copy.
    Parameters:
      `c` - Source to copy.

- ## Method Details

  - ### accept

    public void accept(Visitor v)
    Called by objects that are traversing the nodes of the tree implicitly defined by the contents of a Java class. I.e., the hierarchy of methods, fields, attributes, etc. spawns a tree of objects.
    Specified by:
      `accept` in interface `Node`
    Specified by:
      `accept` in class `Attribute`
    Parameters:
      `v` - Visitor object

  - ### copy

    public Attribute copy(ConstantPool constantPool)
    Specified by:
      `copy` in class `Attribute`
    Parameters:
      `constantPool` - constant pool to save.
    Returns:
      deep copy of this attribute

  - ### dump

    public final void dump(DataOutputStream file) throws IOException
    Dump local variable table attribute to file stream in binary format.
    Overrides:
      `dump` in class `Attribute`
    Parameters:
      `file` - Output file stream
    Throws:
      `IOException` - if an I/O error occurs.

  - ### getLocalVariable

    @Deprecated public final LocalVariable getLocalVariable(int index)
    Deprecated.
    since 5.2 because multiple variables can share the same slot, use getLocalVariable(int index, int pc) instead.
    Parameters:
      `index` - the variable slot
    Returns:
      the first LocalVariable that matches the slot or null if not found

  - ### getLocalVariable

    public final LocalVariable getLocalVariable(int index, int pc)
    Parameters:
      `index` - the variable slot
      `pc` - the current pc that this variable is alive
    Returns:
      the LocalVariable that matches or null if not found

  - ### getLocalVariableTable

    public final LocalVariable[] getLocalVariableTable()
    Returns:
      Array of local variables of method.

  - ### getTableLength

    public final int getTableLength()

  - ### iterator

    public Iterator<LocalVariable> iterator()
    Specified by:
      `iterator` in interface `Iterable<LocalVariable>`

  - ### setLocalVariableTable

    public final void setLocalVariableTable(LocalVariable[] localVariableTable)

  - ### toString

    public final String toString()
    Overrides:
      `toString` in class `Attribute`
    Returns:
      String representation.
