Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.
Here are a couple additional methods for the FieldImpl class. They accomplish the same result as a call to "extract" followed by a call to "getValues". However, by eliminating the creation of a new Field (like "extract" does), they run significantly faster. I implemented them as a new class that extends FieldImpl, but if you like them, you could add them into FieldImpl itself. These are based on the VisAD version with a doc/DATE of Thu Nov 1 09:21:01 CST 2001. (Is that the right way to identify a VisAD version?) <<FieldImplExtended.java>>
