JAVA.CLASS.VIS.SFIELD : Static Field Too Visible (Java)

Summary

Visibility for a static, non-final field is too permissive. In consequence, the internal implementation of objects is accessible and modifiable from outside their class.

Only fields whose visibility is equal to, or more permissive than, the value specified for configuration parameter JAVA_ANALYSIS_FIELD_VISIBILITY are included in checks for this class. Fields whose visibility is more restrictive than the specified value cannot trigger warnings of this class.

Properties

Example

public class C {
  private int f1;
  protected int f2;
  int f3;
  public int f4;
  private final int f5 = 5;;
  protected final int f6 = 6;
  final int f7 = 7;
  public final int f8 = 8;
  private static int f9;
  protected static int f10;             /* "Static Field Too Visible" warning issued here
                                         * when JAVA_ANALYSIS_FIELD_VISIBILITY=PRIVATE
                                         */ 
  static int f11;                       /* "Static Field Too Visible" warning issued here
                                         * when JAVA_ANALYSIS_FIELD_VISIBILITY=PRIVATE
                                         */ 
  public static int f12;                /* "Static Field Too Visible" warning issued here
                                         * when JAVA_ANALYSIS_FIELD_VISIBILITY=PROTECTED (the default) or JAVA_ANALYSIS_FIELD_VISIBILITY=PRIVATE
                                         */
