iguana::RCDBReader Class Reference

#include <RCDBReader.h>

Detailed Description

RCDB reader.

This class interfaces to the RCDB. The database connection path is chosen from one of the following, in order:

• The global variable iguana::GlobalRcdbUrl; by default this is not set to any value (its type is iguana::GlobalParam)
• The environment variable RCDB_CONNECTION (which is likely set if you are on ifarm)
• A default URL, which will be printed in a warning; see iguana::RCDBReader::m_default_url

RCDB will automatically use mariadb / mysql or sqlite, depending on the above RCDB database path, and whether you have satisfied the dependencies.
