Class FileCopier

java.lang.Object

org.mmbase.module.builders.vwms.FileCopier

All Implemented Interfaces:

Runnable

public class FileCopier
extends Object
implements Runnable

A background process that starts file copy commands. The process uses a Queue that holds aFile2Copy objects. The copier is started by file transfer VWMs such as PageMaster, who maintain the queue by filling it with information on files to transfer. FileCopier does not copy files itself, instead, it starts a SCPcopy class for each file to be copied.
