// Revision 1.11  2005/04/19 23:16:18  jimg
// Removed client side parts; the client library is now in libnc-dap.
//
// Revision 1.10  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// Removed old 'virtual ctor' functions which have now been replaced by the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 1.9  2005/03/31 00:04:51  jimg
// Modified to use the factory class in libdap++ 3.5.
//
// Revision 1.8  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 1.7  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 1.6  2004/09/08 22:08:22  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  2004/03/08 19:13:06  jimg
// Removed unnecessary read() method implementation.
//
// Revision 1.4  2003/12/08 18:06:37  edavis
// Merge release-3-4 into trunk
//
// Revision 1.3  2003/09/25 23:09:36  jimg
// Meerged from 3.4.1.
//
// Revision 1.2.8.1  2003/09/06 23:33:14  jimg
// I modified the read() method implementations so that they test the new
// in_selection property. If it is true, the methods will read values
// even if the send_p property is not true. This is so that variables used
// in the selection part of the CE, or as function arguments, will be read.
// See bug 657.
//
// Revision 1.2  2000/10/06 01:22:03  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 00:22:45  jimg
// Added
//
// Revision 1.7  1999/05/07 23:45:33  jimg
// String --> string fixes
//
// Revision 1.6  1998/08/06 16:33:26  jimg
// Fixed misuse of the read(...) member function. Return true if more data
// is to be read, false is if not and error if an error is detected
//
// Revision 1.5  1996/09/17 17:06:45  jimg
// Merge the release-2-0 tagged files (which were off on a branch) back into
// the trunk revision.
//
// Revision 1.4.4.3  1996/09/17 00:26:33  jimg
// Merged changes from a side branch which contained various changes from
// Reza and Charles.
// Removed ncdump and netexec since ncdump is now in its own directory and
// netexec is no longer used.
//
// Revision 1.4.4.2  1996/07/10 21:44:28  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 1.4.4.1  1996/06/25 22:04:48  jimg
// Version 2.0 from Reza.
//
// Revision 1.4  1995/07/09  21:33:53  jimg
// Added copyright notice.
//
// Revision 1.3  1995/06/28  20:22:41  jimg
// Replaced malloc calls with calls to new (and calls to free with calls to
// delete).
//
// Revision 1.2  1995/03/16  16:56:48  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  04:57:58  reza
// Added read and read_val functions.
