Detailed Description

DDLPolyGenerator processes DDL XML Polycone and DDL XML Polyhedra elements.

The PolyGenerator element uses RZPoint elements. The DDLRZPoint can return the r and z std::vectors with the points needed to form the polycone. The RZPoint "accumulator" is also used by the Polyhedra and Polycone elements, and could be used anywhere a pair of std::vectors of r and z values are needed.

Member Function Documentation

void DDLPolyGenerator::preProcessElement ( const std::string &  name, const std::string &  nmspace, DDCompactView &  cpv  )

virtual

Called by loadAttributes AFTER attributes are loaded.

The preProcessElement method can assume that the attributes are loaded and perform any code that is necessary at the start of an element.

This would allow users to call their own code to setup anything necessary for the continued processing of the child elements.

Reimplemented from DDXMLElement.

Definition at line 30 of file DDLPolyGenerator.cc.

References DDXMLElement::clear(), DDLElementRegistry::getElement(), and DDXMLElement::myRegistry_.

  myRegistry_->getElement("RZPoint")->clear();

}

void DDLPolyGenerator::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.
