Detailed Description

DDLLogicalPart processes LogicalPart elements.

DDLLogicalPart.h - description ------------------- begin: Tue Oct 31 2001 email: case@ucdhep.ucdavis.edu

LogicalPart elements simply have the name attribute. However, they also contain elements rSolid and rMaterial. These come together in implementation, but as an XML element the only relevant information to the DDCore is the name attribute. Optionally, they can have instead any Solid or Material elements. To handle the fact that those elements must "stand alone" and also work within LogicalParts, each of those must create a reference (rMaterial or rSolid) to the most recently processed such element.

Member Function Documentation

void DDLLogicalPart::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.

{
  myRegistry_->getElement( "rMaterial" )->clear();
  myRegistry_->getElement( "rSolid" )->clear();
}

void DDLLogicalPart::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.
