GLOBAL.UPAF

Avoid globally unused package-private fields

Description

This rule flags any unused package-private field.

Using Global Static Analysis, Jtest can detect if non-"private" fields/methods/classes are not used by any class.

These unused entities usually point to either:

1. Old code that is no longer needed and which makes the class more difficult to understand.
2. A logical flaw if the entity needs to be used, but other classes incorrectly avoid using it.

Example

See examples/static/GLOBAL/unused.

Repair

Remove the unused field/method/class or document the reason for its existence.
