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.
Overrides:
accept in class Attribute
Parameters:
v - Visitor object

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

getLocalVariableTable

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

getLocalVariable

public final LocalVariable getLocalVariable(int index)
Returns:
first matching variable using index

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)
Overrides:
copy in class Attribute
Returns:
deep copy of this attribute

getTableLength

public final int getTableLength()
