updateFilenameSlots.Raster

This is intended for internal use, though it is exported because other packages
use this. This function exists because when copying file-backed rasters, the
usual mechanism of <code>writeRaster</code> can be very slow. This function allows
for a user to optionally create a hard link to the old file, give it a new
name, then update the filename slot(s) in the <code>Raster*</code> class object. This
can be 100s of times faster for large rasters.

Collection of high-level, machine- and OS-independent tools
for making deeply reproducible and reusable content in R.
The two workhorse functions are Cache and prepInputs;
these allow for: nested caching, robust to environments, and objects with
environments (like functions); and data retrieval and processing
in continuous workflow environments. In all cases,
efforts are made to make the first and subsequent calls of functions have
the same result, but vastly faster at subsequent times by way of checksums
and digesting. Several features are still under active development, including
cloud storage of cached objects, allowing for sharing between users. Several
advanced options are available, see ?reproducibleOptions.

updateFilenameSlots function

<dl><dt>obj</dt>
<dd>An object. This function only has useful methods for <code>Raster*</code>,
with all other classes being simply a pass-through</dd>
<dt>curFilenames</dt>
<dd>An optional character vector of filenames currently existing
and that are pointed to in the obj. If omitted, will take from the <code>obj</code>
using <code>Filenames(obj)</code></dd>
<dt>newFilenames</dt>
<dd>An optional character vector of filenames to use instead of
the curFilenames. This can also be a single directory, in which case the
renaming will be given:
<code>file.path(newFilenames, basename(Filenames(obj, allowMultiple = FALSE)))</code></dd></dl>
