Enumeration Type Documentation

◆ EType

enum EType

Type of geometry shown.

Enumerator
c_Full	Full geometry converted from Geant4 (use this for non-standard Belle II setups!).
c_Simplified	a simplified Belle II geometry.

                {

Function Documentation

◆ removeChildrenByRegExp()

void removeChildrenByRegExp	(	TEveElement *	parent,
		const std::string &	pattern
	)

Recursive removal of volumes based on regular expression pattern.

Leading '#' switches to removal of daughter only.

Definition at line 106 of file EveGeometry.cc.

 {
   TPRegexp reAll(".*");
   bool onlyChildren = false;
   std::string regexp = pattern;
  
   // For patterns with leading '#', do delete only
   // children elements (and remove the '#' for regexp)
   if (pattern.substr(0, 1) == std::string("#")) {
     regexp = pattern.substr(1);
     onlyChildren = true;
   }
  
   TPRegexp reMatch(regexp.c_str());
  
   std::list<TEveElement*> children;
   parent->FindChildren(children, reAll);
  
   for (TEveElement* child : children) {
     if (reMatch.MatchB(child->GetElementName())) {
       if (onlyChildren) {
         B2INFO("Removing children of " << child->GetElementName());
         child->DestroyElements();
       } else {
         B2INFO("Removing " << child->GetElementName());
         child->Destroy();
       }
     } else {
       removeChildrenByRegExp(child, pattern);
     }
   }
 }

◆ saveExtract()

void saveExtract ( )

Save a geometry extract from the current state of the TGeo geometry.

To actually create a reasonably sized extract, one needs to delete all objects in Top_1 that one doesn't want to save. Selecting them via their name and deleting them in a function should work, but really just crashes. This is all quite horrible, really.

Definition at line 202 of file EveGeometry.cc.

◆ setDeleteVolumes()

void setDeleteVolumes ( const std::vector< std::string > & volumes )

List of volumes to be removed.

The volume and all its daughters will be deleted. Leading '#' switches to removal of daughter only.

Definition at line 228 of file EveGeometry.cc.

◆ setHideVolumes()

void setHideVolumes ( const std::vector< std::string > & volumes )

List of volumes to be hidden (can be re-enabled in Eve panel / Geometry scene.

The volume and all its daughters will be hidden.

Definition at line 223 of file EveGeometry.cc.
