Subject [jira] Commented: (OPENJPA-885) Support clear methods on EntityManager, including new CascadeType.CLEAR
Date Wed, 18 Mar 2009 05:35:50 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12682920#action_12682920

Pinaki Poddar commented on OPENJPA-885:
---------------------------------------

    /**
     * Whether openjpa will always cascade on detach, regardless of the
     * cascade setting.
     * 
     * @return true if cascade will always occur, false if cascade will only
     * occur if it is specified in metadata
     * 
     * @since 2.0.0
     */
    public boolean getCascadeWithDetach() {
        return _cascadeWithDetach;
    }


1. What does this new option mean?
2. What will a detached graph of x will look like when this option is set to true? Or false?
What will be the difference?
3. How does this option differ from three existing option of 'loaded', 'fetch-group' and 'all'?
4. Why is this option in Compatibility? What previous behavior that has now changed so that
user can fall back upon to access old behavior?
