Package io.virtdata.docsys.metafs.fs.renderfs.fs

Class RenderFS

java.lang.Object

java.nio.file.FileSystem

io.virtdata.docsys.metafs.core.MetaFS

io.virtdata.docsys.metafs.fs.virtual.VirtFS

io.virtdata.docsys.metafs.fs.renderfs.fs.RenderFS

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public class RenderFS
extends VirtFS

The RenderFS filesystem will pretend that a rendered form of some file types already exist in the filesystem, so long as the necessary input file type and rendererTypes are present. Directory listings, file access, and everything else that would normally work for these files will work. RenderFS will create in-memory versions of these files as needed. The rendered version of files automatically take on all the attributes of their upstream file format, except for file size and file data.
