FilterFileSystem

public FilterFileSystem(FilterFileSystemProvider parent,
                        java.nio.file.FileSystem delegate)

Construct a FilterFileSystem based on the specified base filesystem.

Note that base filesystem is closed if this filesystem is closed, however the default filesystem provider will never be closed, it doesn't support that.

Parameters:

delegate - specified base channel.
