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 and accessing JBoss VFS in the classpath.

As of Spring 4.0, this class supports VFS 3.x on JBoss AS 6+ (package org.jboss.vfs) and is in particular compatible with JBoss AS 7 and WildFly 8.

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
