Subject [jira] [Commented] (LANG-965) FieldUtils methods leak accessible flags
Date Thu, 16 Oct 2014 06:26:34 GMT

    [ https://issues.apache.org/jira/browse/LANG-965?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14173424#comment-14173424

Benedikt Ritter commented on LANG-965:
--------------------------------------

This needs more thought. There is a fundamental problem with getField, since neither the user
nor we can tell if the accessibility has been changed after we have handed the field out of
the API. My opinion is, to get this right we will have to implement something like:

{code:java}
FieldUtils.doWithField("fieldName", true, new FieldAccessCallback(Field theField) {
   // user can do something with the field here
});
{code}

In doWithField we can restore the accessibility after we have called the callback.

> When various FieldUtils methods are called the accessible is set to true but never reset
to false. This is side-effect should be cleaned up.
> This makes a mess of the object model which represents the class meta data.
