  // As in the case of 'CbmTofHit' a separate matching branch exists,
  // its member variable 'fMatch' never points to a valid 'CbmMatch' object.
  // For this reason, NOT calling the 'CbmHit' destructor (wherein a valid
  // 'fMatch' would be deleted) through 'TClonesArray::Delete' does NOT cause
  // a memory leak upon constructing new 'CbmTofHit' objects in the output
  // array performing a placement new operation on the 'TClonesArray'.
  // On the contrary, digi-to-point links are (currently) not stored in a
  // separate matching branch but streamed with the 'CbmDigi' object.
  // If the digis which are read from the input 'TTree' do contain valid
  // 'fMatch' pointers, copy-constructing them in the "TofCalDigi" output
  // array will be accompanied with memory allocation. Without calling the
  // destructors of objects in "TofCalDigi" through 'TClonesArray::Delete'
