Constructor Detail

AbstractLocalVariableTable

public AbstractLocalVariableTable(AbstractLocalVariableTable c)

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

AbstractLocalVariableTable

public AbstractLocalVariableTable(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

dump

public final void dump(java.io.DataOutputStream file)
                throws java.io.IOException

Dump local variable table attribute to file stream in binary format.

Overrides:

dump in class Attribute

Parameters:

file - Output file stream

Throws:

java.io.IOException

getLocalVariableTable

public final LocalVariable[] getLocalVariableTable()

Returns:

Array of local variables of method.

getLocalVariable

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:

first matching variable using index

getLocalVariable

public final LocalVariable getLocalVariable(int index,
                             int pc)

Parameters:

index - the variable slot

pc - the current pc that this variable is alive

Returns:

matching variable using index when variable is used at supplied pc

setLocalVariableTable

public final void setLocalVariableTable(LocalVariable[] local_variable_table)

toString

public final java.lang.String toString()

Overrides:

toString in class Attribute

Returns:

String representation.

copy

public Attribute copy(ConstantPool _constant_pool)

Specified by:

copy in class Attribute

Returns:

deep copy of this attribute

getTableLength

public final int getTableLength()
