/*
* $Log: NCArray.h,v $
* Revision 1.16 2005/04/19 23:16:18 jimg
* Removed client side parts; the client library is now in libnc-dap.
*
* Revision 1.15 2005/04/11 18:38:20 jimg
* Fixed a problem with NCSequence where nested sequences were not flagged
* but instead were translated. The extract_values software cannot process a
* nested sequence yet. Now the code inserts an attribute that notes that a
* nested sequence has been elided.
*
* Revision 1.14 2005/04/08 17:08:47 jimg
* Removed old 'virtual ctor' functions which have now been replaced by the
* factory class code in libdap++.
*
* Revision 1.13 2005/03/31 00:04:51 jimg
* Modified to use the factory class in libdap++ 3.5.
*
* Revision 1.12 2005/02/26 00:43:20 jimg
* Check point: This version of the CL can now translate strings from the
* server into char arrays. This is controlled by two things: First a
* compile-time directive STRING_AS_ARRAY can be used to remove/include
* this feature. When included in the code, only Strings associated with
* variables created by the translation process will be turned into char
* arrays. Other String variables are assumed to be single character strings
* (although there may be a bug with the way these are handled, see
* NCAccess::extract_values()).
*
* Revision 1.11 2005/02/17 23:44:13 jimg
* Modifications for processing of command line projections combined
* with the limit stuff and projection info passed in from the API. I also
* consolodated some of the code by moving d_source from various
* classes to NCAccess. This may it so that DODvario() could be simplified
* as could build_constraint() and store_projection() in NCArray.
*
* Revision 1.10 2005/01/26 23:25:51 jimg
* Implemented a fix for Sequence access by row number when talking to a
* 3.4 or earlier server (which contains a bug in is_end_of_rows()).
*
* Revision 1.9 2004/11/30 22:11:35 jimg
* I replaced the flatten_*() functions with a flatten() method in
* NCAccess. The default version of this method is in NCAccess and works
* for the atomic types; constructors must provide a specialization.
* Then I removed the code that copied the variables from vectors to
* lists. The translation code in NCConnect was modified to use the
* new method.
*
* Revision 1.8 2004/10/28 16:38:19 jimg
* Added support for error handling to ClientParams. Added use of
* ClientParams to NCConnect, although that's not complete yet. NCConnect
* now has an instance of ClientParams. The instance is first built and
* then passed into NCConnect's ctor which stores a const reference to the CP
* object.
*
* Revision 1.7 2004/10/22 21:51:34 jimg
* More massive changes: Translation of Sequences now works so long as the
* Sequence contains only atomic types.
*
* Revision 1.6 2004/09/08 22:08:21 jimg
* More Massive changes: Code moved from the files that clone the netCDF
* function calls into NCConnect, NCAccess or nc_util.cc. Much of the
* translation functions are now methods. The netCDF type classes now
* inherit from NCAccess in addition to the DAP type classes.
*
* Revision 1.5 2003/12/08 18:06:37 edavis
* Merge release-3-4 into trunk
*
* Revision 1.4 2003/09/25 23:09:36 jimg
* Meerged from 3.4.1.
*
* Revision 1.3.4.2 2003/06/24 11:36:32 rmorris
* Removed #pragma interface directives for the OS X.
*
* Revision 1.3.4.1 2003/06/07 22:02:32 reza
* Fixed char vs. byte and long vs. nclong error checks.
*
* Revision 1.3 2002/05/03 00:01:52 jimg
* Merged with release-3-2-7.
*
* Revision 1.2.4.1 2001/12/26 03:32:24 rmorris
* Removed redundant default args. VC++ only allows them to be specified
* a single time.
*
* Revision 1.2 2000/10/06 01:22:02 jimg
* Moved the CVS Log entries to the ends of files.
* Modified the read() methods to match the new definition in the dap library.
* Added exception handlers in various places to catch exceptions thrown
* by the dap library.
*
* Revision 1.1 1999/07/28 00:22:42 jimg
* Added
*
* Revision 1.5 1999/05/07 23:45:31 jimg
* String --> string fixes
*
* Revision 1.4 1996/09/17 17:06:17 jimg
* Merge the release-2-0 tagged files (which were off on a branch) back into
* the trunk revision.
*
* Revision 1.3.4.2 1996/07/10 21:43:55 jimg
* Changes for version 2.06. These fixed lingering problems from the migration
* from version 1.x to version 2.x.
* Removed some (but not all) warning generated with gcc's -Wall option.
*
* Revision 1.3.4.1 1996/06/25 22:04:19 jimg
* Version 2.0 from Reza.
*
* Revision 1.3 1995/03/21 20:58:16 jimg
* Resolved conflicts between my (jhrg) files and those checked in by Reza.
*
* Revision 1.2 1995/03/16 16:56:26 reza
* Updated for the new DAP. All the read_val mfunc. and their memory management
* are now moved to their parent class.
* Data transfers are now in binary while DAS and DDS are still sent in ASCII.
*
* Revision 1.1 1995/02/10 04:57:15 reza
* Added read and read_val functions.
