This element is used to specify parameters for a part in the detector. PartSelector provides a way to associate Parameters with specific parts of the detector.

void DDLSpecPar::processElement ( const std::string &  name, const std::string &  nmspace, DDCompactView &  cpv  )

virtual

Processing the element.

The processElement method completes any necessary work to process the XML element.

For example, this can be used to call the DDCore to make the geometry in memory. There is a default for this so that if not declared in the inheriting class, no processing is done.

08/13/03 doNotEval for Parameter is based on the value of the eval flag. For String it is always false and for Numeric it is always true. But for "legacy" Parameter, remember, we need to check eval. Default is NOT to evaluate.

1. Check eval flag of each level (SpecParSection, SpecPar and Parameter).
2. Default is the closest specified eval attribute with any value other than "false".

Reimplemented from DDXMLElement.
