Constructor & Destructor Documentation

pat::DiObjectProxy::DiObjectProxy ( )

inline

Default constructor, requested by ROOT. NEVER use a default constructed item!

Definition at line 23 of file PATDiObjectProxy.h.

: cand1_(nullptr), cand2_(nullptr), type1_(nullptr), type2_(nullptr), totalP4ok_(false), totalP4_()  {}

pat::DiObjectProxy::DiObjectProxy ( const reco::Candidate &  c1, const reco::Candidate &  c2  )

inline

Constructor of the pair from two Candidates Note: the Proxy MUST NOT outlive the Candidates, otherwise you get dangling pointers
