Detailed Description

Helper class which provides logic for matching Source values to Src instances.

This is an abstraction of the set of addresses. Having this set one can ask questions like:

• does a specific address (Pds::Src instance) belong to the set (match() method).
• does other set (another SrcMatch instance) contains this set completely (so that for example one could ask question like "will this set match cspad-only devices")
• check if this is a special "no-source" match (matching only data that do not come from any device)
• check if this is "exact" match (matching only one specific device, or no-source)

Internal representation of this object is Pds::Src instance with some special bit patterns representing special cases. This representation may change if these patterns become unavailable (if DAQ decides to use them for some purpose).
