Class VFS

java.lang.Object
com.tccc.kos.commons.core.vfs.AbstractVFSSource
com.tccc.kos.commons.core.vfs.VFS
All Implemented Interfaces:
VFSParent, VFSSource
public class VFS extends AbstractVFSSource implements VFSParent
Allows multiple VFS sources to be virtually mounted to form a virtual read-only filesystem. This is very simple and only allows opening of files but doesn't even include enumeration so mostly useful for serving content and such, where the requester already knows what it's looking for.
