org.springframework.core.io
Class VfsUtils

java.lang.Object
  extended by org.springframework.core.io.VfsUtils
Direct Known Subclasses:
VfsPatternUtils
public abstract class VfsUtils
extends java.lang.Object

Utility for detecting the JBoss VFS version available in the classpath. JBoss AS 5+ uses VFS 2.x (package org.jboss.virtual) while JBoss AS 6+ uses VFS 3.x (package org.jboss.vfs).

Thanks go to Marius Bogoevici for the initial patch. Note: This is an internal class and should not be used outside the framework.

Since:
3.0.3
