Include files for libdap

Guidelines for including headers

In our code that uses libdap, we should make sure to prefix the libdap headers that are included with

libdap/

like this:

   #include <libdap/BaseType>

This is because some of the names used by the libdap headers are also used by C++ or the STL or are close enough to those names to cause problems with various software development tools.

It's best to use double quotes for headers from within a project and angle brackets for those from outside the project. So, use angle brackets with libdap headers in the BES code; use double quotes for BES headers in the BES code.

Group headers like this:

• First include "config.h"
• Then system headers
• Then C/C++ library headers
• Then libraries (like libdap)
• Then BES headers

Never include

config.h

in a header that will be installed (which is essentially every header).

Minimise headers included in other headers.

Never put

using namespace xxx

in a header - it's a great way to cut down on the wordiness of an implementation (.cc) but in a header it will introduce that using statement to all of the code that directly or indirectly includes the header.
