org.autoplot.cdf.CdfDataSource

CDF data source based on Nand Lal's pure-Java CDF reader. CDF, or Common Data Format, is a NASA data format.

CdfDataSource( java.net.URI uri )

timer

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.

checkCdf

checkCdf( java.io.File cdfFile ) → void

check if the file really is a CDF, and throw IllegalArgumentException if it is not. NetCDF files occasionally use the extension .cdf.

Parameters

cdfFile - a CDF file (or not)

Returns:

void (returns nothing)

getCdfFile

getCdfFile( String fileName ) → gov.nasa.gsfc.spdf.cdfj.CDFReader

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.

Parameters

fileName - a String

Returns:

the CDF reference used to access the file
