template<class T >

void Mantid::DataHandling::DefaultEventLoader::makeMapToEventLists ( std::vector< std::vector< T > > & vectors )

private

Map detector IDs to event lists.

Generate a look-up table where the index = the pixel ID of an event and the value = a pointer to the EventList in the workspace.

Parameters

vectors :: the array to create the map on
