'source' and 'target' will always be non-null. The 'variant' will be non-null only if a non-empty variant was parsed.
'sawSource' is true if there was an explicit source in the parsed id. If there was no explicit source, then an implied source of ANY is returned and 'sawSource' is set to false.
'filter' is the parsed filter pattern, or null if there was no filter.
