All Superinterfaces:

Comparable<Location>, Location
```
public interface Label
extends Location
```
A label is used to manipulate a branch instruction's branch location. A label has a location address. Branch instructions have origin addresses, which contain the address of the opcode that performs the conditional or unconditional branch.
Labels are generated by factory methods in the CodeBuilder class. If a label has any origin addresses, its location address must be set by the time the CodeBuilder's class file is output.
