template<typename T>
T getParam(const std::string &key, dd4hep::DetElement &elt)¶ Helper function to extract a parameter value from a dd4hep detector element from VariantParameters.
- Template Parameters
T – The value type
- Parameters
key – The key of the value to extract
elt – The detector element instance
- Returns
A copy of the value contained in the params instance
-
template<typename T>
T getParamOr(const std::string &key, const dd4hep::DetElement &elt, T alternative)¶ Get a parameter value or an alternative value if either the VariantParameters extension isn’t set, or it doesn’t contain the demanded key.
- Template Parameters
T – The value type
- Parameters
key – The key of the value to extract
elt – The detector element instance
alternative – The value to return if no params are set of the key doesn’t exist
- Returns
The value behind key, or
alternative
-
inline dd4hep::rec::VariantParameters &getParams(dd4hep::DetElement &elt)¶
Helper function to extract a VariantParameters instance.
- Parameters
elt – The detector element instance
- Returns
The VariantParameters instance
-
inline const dd4hep::rec::VariantParameters &getParams(const dd4hep::DetElement &elt)¶
Helper function to extract a VariantParameters instance, const version.
- Parameters
elt – The detector element instance
- Returns
The VariantParameters instance
-
inline bool hasParam(const std::string &key, dd4hep::DetElement &elt)¶
Check if a detector element has a key set in its VariantParameters.
- Parameters
key – The key to check existance for
elt – The detector element instance
- Returns
True if the element has VariantParameters and the key exists, false if either of these is not true
