◆ afterAlignment()

void AlignmentMonitorTemplate::afterAlignment ( )

overridevirtual

Called after updating AlignableTracker and AlignableMuon (by "endOfLoop()"): may be reimplemented

Reimplemented from AlignmentMonitorBase.

Definition at line 129 of file AlignmentMonitorTemplate.cc.

◆ book()

void AlignmentMonitorTemplate::book ( )

Book or retrieve histograms; MUST be reimplemented.
