checkParameters()

void RIO_OnTrackErrorScaling::checkParameters ( const char * label, unsigned int n_paramter_sets, const char *const * param_names, unsigned int n_paramters ) const

protectedinherited

Convenience function to check whether the number of parameters is correct.

Parameters

label	a label for the error scaling class in case an error is issued.
n_paramter_sets	the number of parameter sets
param_names	the names of the parameter sets
n_paramters	the number of parameters per set.

Definition at line 14 of file RIO_OnTrackErrorScaling.cxx.
