libdap::DDS * get_dds()
error object created from libdap error objects and can handle those errors
Definition: BESDapError.h:59
Structure storing information used by the BES to handle the request.
std::map< std::string, std::string > data
the map of string data that will be required for the current request.
void first_container()
set the container pointer to the first container in the containers list
Abstract exception class for the BES with basic string message.
Definition: BESError.h:58
exception thrown if an internal error is found and is fatal to the BES
Abstract base class representing a specific set of information in response to a request to the BES.
The service registry allows modules to register services with the BES that they provide.
virtual bool service_available(const std::string &name, const std::string &cmd="", const std::string &format="")
Determines if a service and, optionally, a command and a return format, is available.
container for a DAS and DDS needed to write out the usage information for a dataset.
