moab::gs_data::gs_data ( uint  n, const long *  label, const Ulong *  ulabel, uint  maxv, const unsigned int  nlabels, const unsigned int  nulabels, crystal_data *  crystal, ErrorCode &  Init_Result  )

inline

Constructor for moab_gs_data: takes all arguments and initializes moab_gs_data. If needs_reset is false after calling constructor, initialization has failed.

param n number of tuples in tuple list param label pointer to signed labels param ulabel pointer to unsigned labels param maxv max vector size param nlabels number of signed long labels (not including gid) param nulabels number of unsigned long labels param crystal moab_crystal_data contains MPI_Comm and is used for message passing
