# Interface LineNumberTableAttribute

All Superinterfaces:
  `Attribute<LineNumberTableAttribute>, ClassFileElement`

public sealed interface LineNumberTableAttribute extends Attribute<LineNumberTableAttribute>
Models the `LineNumberTable` attribute (JVMS 4.7.12), which records the mapping between indexes into the `code` array and line numbers in the source file. Its entries are delivered as `LineNumber` when traversing the elements of a `CodeModel`, which is toggled by `ClassFile.LineNumbersOption`.

This attribute only appears on `Code` attributes, and permits multiple instances in a `Code` attribute. It has a data dependency on labels.

This attribute cannot be sent to a `CodeBuilder`; its entries can be constructed with `LineNumber`, resulting in at most one attribute instance in the built `Code` attribute.

The attribute was introduced in the Java Platform version 1.0.2, major version 45.
