DAP2Exception (OPeNDAP 4.5.4 API)

java.lang.Object
- java.lang.Throwable
- - java.lang.Exception
  - - opendap.dap.DAP2Exception

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

BadURLException, DAP2ServerSideException, DASException, DDSException, InvalidDimensionException
```
public class DAP2Exception
extends Exception
```
Holds an exception thrown by OPeNDAP server to a client.
Unlike the other OPeNDAP exceptions, this one contains extra methods to get the various fields sent by the server, and a parse method to parse the Error sent from the server.
This class will be changing it's name to opendap.dap.DAP2Exception. I expect that it will be deprecated in the next release.
You've been warned.
