public java.nio.file.FileSystem getFileSystem(java.net.URI uri)

getPath

public java.nio.file.Path getPath(java.net.URI uri)

Meta Details

Although this is a meta FS, and the URIs are essentially symbolic, we still enforce that the logical nesting of a filesystem URI and a path URI will determine when this method will return a valid value. In other words, a path will not be returned for a meta file system wherein the URI of that file system does not logical contain the inner path. This should maintain important semantics about usage and filtering that developers may take for granted.

Overrides:

getPath in class MetaFSProvider
