Constructor & Destructor Documentation

MutableTrackContainerHandlesHelper()

template<class PropOwner>

ActsTrk::MutableTrackContainerHandlesHelper::MutableTrackContainerHandlesHelper

(

PropOwner *

owner

)

Constructor taking the pointer to the class holding the object used to declare the data dependency from the WriteHandleKeys to the AvalancheScheduler.

The object should be defined in the header like ActsTrk::MutableTrackContainerHandlesHelper m_trackHelper{this};

initialize()

StatusCode ActsTrk::MutableTrackContainerHandlesHelper::initialize

(

const std::string &

prefix

)

Sets up the handles.

• prefix - common prefix for all the names the value would typically be taken from configurable string property

moveToConst() [2/2]

produces ActsTrk::ConstTrackContainer with all backends stored in SG

• tc - MutableTrackContainer the source (will be disassembled after the operation)
• - geoContext - geometry context, needed in surfaces conversion
• evtContext - event context (needed for SG operations)
