This is the processor for CompositeMaterial DDL elements.

The CompositeMaterial is an element that contains other elements. In particular, it contains rMaterial elements which are references either to other Composite or Elementary materials.

Member Function Documentation

void DDLCompositeMaterial::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 33 of file DDLCompositeMaterial.cc.

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

{
  // fyi: no need to clear MaterialFraction because it is cleared at the end of each
  // CompositeMaterial
  myRegistry_->getElement( "rMaterial" )->clear();
}

void DDLCompositeMaterial::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.

  // The parent element CompositeMaterial MUST be in the same namespace as this fraction.
  // additionally, because it is NOT a reference, we do not try to dis-entangle the namespace.

  // the "raw" name attribute.

  // TO DO:  sfractions assumes that the values are "mixture by weight" (I think)
  // we need to retrieve the fraction attributes and then check the method
  // attribute of the CompositeMaterial to determine if the numbers go straight
  // in to the DDCore or if the numbers need to be manipulated so that the 
  // sfractions are really mixtures by weight going into the DDCore.  Otherwise,
  // the DDCore has to know which are which and right now it does not.
