The LineNumberTable
attribute is an optional
variable-length attribute in the attributes
table of a
Code
attribute. It may be used by debuggers to
determine which part of the Java Virtual Machine code
array corresponds to a given line number in the original Java source
file. If LineNumberTable
attributes are present in the
attributes
table of a given Code
attribute,
then they may appear in any order. Furthermore, multiple
LineNumberTable
attributes may together represent a
given line of a Java source file; that is,
LineNumberTable
attributes need not be one-to-one with
source lines.
