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.

Constructor Index

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

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()

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(short name_index,
                        int length,
                        LineNumber line_number_table[],
                        ConstantPool constant_pool)

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
