Examples of SpoolFile

org.exoplatform.services.jcr.impl.util.io.SpoolFile
Created by The eXo Platform SAS Author : Peter Nedonosko peter.nedonosko@exoplatform.com.ua 05.10.2007 For use in TransienValueData (may be shared in the Workspace cache with another Sessions). Spool files used in ValueData for incoming values managed by SpoolFile class. Spool file may be created with constructor or be obtained from static method createTempFile(String, String, File), which itself create physical file using File.createTempFile(prefix, suffix, directory) call. Spool file may be acquired for usage by any object (SpoolFile.acquire(Object)). Till this object will call release (SpoolFile.release(Object)) or will be garbage collected it's impossible to delete the spool file (by File.delete() method). Spool file will be created in TransientValueData during a source stream spool operation (caused by getAsBytes() or getAsStream()). This file is a own of this ValueData, which itself contains in Property and Session. After the save this file (as part of ValueData) will become a part of workspace cache and may be shared with other sessions. After the JCR core restart (JVM restart) ValueData will use file/BLOB from workspace storage. @author Peter Nedonosko @version $Id: SpoolFile.java 11907 2008-03-13 15:36:21Z ksm $
