Detailed Description

DDLMap handles Map container.

Author:: Michael Case

DDLMap.h - description ------------------- begin: Fri Nov 28, 2003 email: case@ucdhep.ucdavis.edu

This is the Map container. It is a c++ stye std::map <std::string, double> and has a name associated with the Map for the DDD name-reference system.

void DDLMap::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 76 of file DDLMap.cc.

References pDouble, pMap, pName, and pNameSpace.

{
  pName = "";
  pMap.clear() ;
  //pMapMap.clear(); only the DDLAlgorithm is allowed to clear this guy!
  pDouble = 0.0;
  pNameSpace = nmspace;
}

void DDLMap::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.
