An AlgoPosPart (or Algorithmic Positioning Part) is used to repeatedly position a LogicalPart somewhere inside it's parent. So, an AlgoPosPart needs two rLogicalParts (self and parent) on which to operate, an Algorithm and it's parameters.

Member Function Documentation

void DDLAlgoPosPart::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.

Reimplemented from DDXMLElement.
