Subject: [lang] Using ReflectionToStringBuilder and excluding secure fields

Hello: 

Right now, I use the code below to exclude password fields from output.

    /**
     * Builds a String for a toString method excluding the given field
name.
     * 
     * @param obj
     *            The object to "toString".
     * @param excludeFieldName
     *            The field name to exclude
     * @return The toString String.
     */
    public static String toStringExcluding(Object obj, final String
excludeFieldName) {
        return (new ReflectionToStringBuilder(obj) {
            protected boolean accept(Field f) {
                return super.accept(f) &&
!f.getName().equals(excludeFieldName);
            }
        }).toString();
    }

I could imagine writing my call sites like this instead:

new ReflectionToStringBuilder(obj).setExcludeFields(new
String[]{"password"}).toString();

Which means adding the set/getExcludeFields() feature.

Any thoughts?

Gary
