Interface LineNumber

All Superinterfaces:
ClassFileElement, CodeElement, PseudoInstruction
public sealed interface LineNumber extends PseudoInstruction
A pseudo-instruction which indicates the code for a given line number starts after the current position in a Code attribute. This models a single entry in the LineNumberTable attribute. Delivered as a CodeElement during traversal of the elements of a CodeModel, according to the setting of the ClassFile.LineNumbersOption option.

A line number entry is composite: 

LineNumber(int line)

Another model, LineNumberInfo, also models a line number entry; it has no dependency on a CodeModel and represents of bci values as ints instead of order of pseudo-instructions in the elements of a CodeModel, and is used as components of a LineNumberTableAttribute.

API Note:
Line numbers are represented with custom pseudo-instructions to avoid using labels, which usually indicate branching targets for the control flow.
