Draft: AthConfigFlags: add hasValue method
Add the hasValue
method that can be used to check if a flag has a
value.
My use-case is to be able to check if the user has set an explicit value for flags.IOVDb.GlobalTag
which is otherwise auto-configured by IOVDbAutoCfgFlags. However, this method doesn't take into account the default settings for the HLT. An alternative could be to add that code directly into IOVDbAutoCfgFlags
.
Would like to hear opinions from e.g. @tbold @tamartin @wlampl @tadej.
