Class VfsUtils

java.lang.Object

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
