Pds::Epics Namespace Reference.
EPICS (Experimental Physics and Industrial Control System) is used for hardware control and readout of hardware status, values etc. These are called process variables (PV). pdsdata contains a package that holds the epics classes needed to read the process variables from the xtc file. This is not even a complete documentation of these classes, as it would be unneccesarily detailed. Here we aim just to include the main ingredients and what the user need to know to extract the data.
