Detailed Description

defines a bidirectional (many to many) mapping between TObjects in DataStore and their visual representation.

This is used to allow retrieving the original objects for a given TEveElement (to show additional info), and vice versa.

Member Function Documentation

add()

void add	(	const TObject *	dataStoreObject,
		TEveElement *	visualRepresentation
	)

Generic function to keep track of which objects have which visual representation.

Should be called by functions adding TEveElements to the event scene (Hits are currently excluded).

Does not take ownership of given objects, just stores mapping between pointers.

Definition at line 134 of file VisualRepMap.cc.

{
  if (!dataStoreObject) {
    B2ERROR("Trying to insert NULL for object represented by " << visualRepresentation->GetElementName());
    return;
  }
  auto ret = m_dataStoreEveElementMap->insert(DataStoreEveElementMap::value_type(dataStoreObject, visualRepresentation));
  if (!ret.second) {
    B2DEBUG(100, "Failed to insert object represented by " << visualRepresentation->GetElementName() << "! Duplicate?");
  }
}

clear()

void clear

(

void

)

Remove all contents in map.

(call this after each event)

Definition at line 46 of file VisualRepMap.cc.

getDataStoreObject()

const TObject * getDataStoreObject

(

TEveElement *

elem

)

const

Get object represented by given visual representation.

(elem is pretty much const, but boost refuses to search for it then. )

Definition at line 56 of file VisualRepMap.cc.

isCurrentlySelecting()

bool isCurrentlySelecting ( ) const

inline

are we currently in a select() call?

Call this in your selection handler and abort if true. (otherwise we end up recursively calling ourselves).

Definition at line 50 of file VisualRepMap.h.

{ return m_currentlySelecting; }
