Method Detail

checkout

public org.jdom.Document checkout()

Returns a cloned copy of the document.

checkin

public void checkin(org.jdom.Document document)

Accepts the changes from the document. If possible, rewrites the content. Changes are synchronized but not checked; if two concurrent threads make different changes, the last one to call checkin() will win. This effectively gives the process a transaction isolation level equivalent to TRANSACTION_READ_COMMITTED.
