<h2>org.autoplot.cdf.CdfDataSource</h2><p>CDF data source based on Nand Lal's pure-Java
CDF reader. CDF, or Common Data Format, is a NASA data format.</p>

<p>To resolve bug 1002 we unload the cache after 10 seconds. Joe at Aerospace had a problem where
he couldn't kill a lingering autoplot process and then couldn't get at the file because it held a reference to the
file. Now we automatically unload all the cached files. I did look at just disabling the cache, but the file is
open and closed three times during the load. See http://sourceforge.net/p/autoplot/bugs/1002.</p>

<h2>checkCdf</h2>
checkCdf( <a href='https://docs.oracle.com/javase/8/docs/api/java/io/File.html'>java.io.File</a> cdfFile ) → void
<p>check if the file really is a CDF, and throw IllegalArgumentException if it is not.
NetCDF files occasionally use the extension .cdf.</p>
<h3>Parameters</h3>
cdfFile - a CDF file (or not)
<h3>Returns:</h3>
void (returns nothing)

<p>get the abstract access object to the given CDF file. This provides read-only access to the file, and a cache
is used to limit the number of references managed.
See bug http://sourceforge.net/p/autoplot/bugs/922/
The result returns a CDF object which contains a read-only memory-mapped byte buffer.</p>
<h3>Parameters</h3>
fileName - a String
<h3>Returns:</h3>
the CDF reference used to access the file

<p>get the dataset for svariable from the CDF file, implementing virtual variables if needed. This supports for
svariable:
<ul>
<li> X;Y;Z where each is read and linked together
<li> X[0:100] where the first 100 records are read
<li> X[::5] where every fifth record is read
<li> virtual variables.
