org.jboss.virtual.plugins.vfs.helpers.LazyInputStream
- All Implemented Interfaces:
- java.io.Closeable
public class LazyInputStream
- extends java.io.InputStream
Lazy input stream.
Delaying opening stream from underlying virtual file as long as possible.
Won't be opened if not used at all.
Synchronization is very simplistic, as it's highly unlikely
there will be a lot of concurrent requests.
