public final class LineNumberTable
extends Attribute
This class is derived from Attribute and represents a table of line numbers for debugging purposes. This attribute is used by the Code attribute. It contains pairs of PCs and line numbers.

See Also:
Code, LineNumber

Variable Index

o constant_pool
o line_number_table
o line_number_table_length

Constructor Index

o LineNumberTable()
Empty constructor, all attributes have to be defined via `setXXX' methods.
o LineNumberTable(int, int, DataInputStream, ConstantPool)
Construct object from file stream.
o LineNumberTable(int, int, LineNumber[], ConstantPool)
o LineNumberTable(LineNumberTable)
Initialize from another object.

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 line number table attribute to file stream in binary format.
o getConstantPool()
o getLineNumberTable()
o setConstantPool(ConstantPool)
o setLineNumberTable(LineNumber[])
o toString()

Variables

o line_number_table_length 
 private int line_number_table_length
o line_number_table 
 private LineNumber line_number_table[]
o constant_pool 
 private ConstantPool constant_pool

Constructors

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

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

o LineNumberTable 
 public LineNumberTable(int name_index,
                        int length,
                        LineNumber line_number_table[],
                        ConstantPool constant_pool)
o LineNumberTable 
 LineNumberTable(int name_index,
                 int length,
                 DataInputStream file,
                 ConstantPool constant_pool) throws IOException
Construct object from file stream.

Parameters:
name_index - Index of name
length - Content length in bytes
file - Input stream
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 line number 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 getLineNumberTable 
 public final LineNumber[] getLineNumberTable()
Returns:
Array of (pc offset, line number) pairs.
o setConstantPool 
 public final void setConstantPool(ConstantPool constant_pool)
Parameters:
constant_pool - Constant pool to be used for this object.
See Also:
ConstantPool
o setLineNumberTable 
 public final void setLineNumberTable(LineNumber line_number_table[])
o toString 
 public final String toString()
Returns:
String representation.
Overrides:
toString in class Object
