GLOBAL.DPPF

Declare "public"/"protected" fields as inaccessible as possible

Description

This rule flags any "public"/"protected" field that is more accessible than necessary.

Using Global Static Analysis, Jtest can detect if non-"private" fields/methods/classes can be made less accessible.

Making the fields/methods/classes as inaccessible as possible makes the code much more object-oriented and it is much easier to understand code dependencies.

Example

See examples/static/GLOBAL/too-accessible.

Repair

Change the field's accessibility or document the reason for the excessive accessibility.
