Method Details

expand

public File expand()

Description copied from interface: File

Expands this file to a file with a more precise type.

During expansion, record types may get new fields, never lose them.

This file object may or may not be mutable. If this file is immutable and is expanded, returns the new file. If this file is mutable, returns this file regardless of whether expansion occurred; the caller cannot discern whether expansion occurred.

Specified by:

expand in interface File

Overrides:

expand in class Files.UnknownFile
