Constructor Detail

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.

LocalVariableTable

public LocalVariableTable(int name_index, int length, LocalVariable[] local_variable_table, ConstantPool constant_pool)

Parameters: name_index Index in constant pool to `LocalVariableTable' length Content length in bytes local_variable_table Table of local variables constant_pool Array of constants

Method Detail

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

copy

public Attribute copy(ConstantPool constant_pool)

Returns: deep copy of this attribute

dump

public final void dump(DataOutputStream file)
Dump local variable table attribute to file stream in binary format.

Parameters: file Output file stream

Throws: IOException

getLocalVariable

public final LocalVariable getLocalVariable(int index)

Returns: first matching variable using index

getLocalVariableTable

public final LocalVariable[] getLocalVariableTable()

Returns: Array of local variables of method.

getTableLength

public final int getTableLength()

setLocalVariableTable

public final void setLocalVariableTable(LocalVariable[] local_variable_table)

toString

public final String toString()

Returns: String representation.
