___version=13.1.2_dev http://chemapps.stolaf.edu/jmol/Jmol-13.zip
new feature: (JmolViewer) public void cacheFile(String fileName, byte[]
bytes)
-- allows a mechanism for applets or embedding apps to deliver file
content as bytes
-- for applets, first getPropertyAsJavaObject("Viewer")
So this should be a general way to deliver a byte array to Jmol. Basically
what it does is to cache the bytes in memory. Then any later script
reference to fileName will instead get those bytes. If you use null for
fileName, then the cache will be cleared. Or, better, the cache will be
cleared with the script command
reset cache
or
cache remove all
Basically, then, if you need to load binary data:
1) find a way to get that data using AJAX.
2) use Jmol.getPropertyAsJavaObject(jmol,
"JmolViewer").cacheFile("url_of_your_data", data)
3) then just send a script to Jmol -- LOAD "url_of_your_data;cache remove
all"
Example is attached.
