# Enum Class ClassFile.LineNumbersOption

java.lang.Object
java.lang.Enum<ClassFile.LineNumbersOption>
java.lang.classfile.ClassFile.LineNumbersOption

All Implemented Interfaces:
  `Serializable`, `ClassFile.Option`, `Comparable<ClassFile.LineNumbersOption>`, `Constable`

Enclosing interface:
  `ClassFile`

public static enum ClassFile.LineNumbersOption extends Enum<ClassFile.LineNumbersOption> implements ClassFile.Option
The option describing whether to process or discard `LineNumber`s in the traversal of a `CodeModel` or a `CodeBuilder`. The default is `PASS_LINE_NUMBERS` to process all line number entries as all other `CodeElement`.

Discarding line numbers may reduce the overhead of parsing or transforming `class` files and has no impact on the run-time behavior.
