#include <expressions.hpp>
This struct holds static arrays of pointers to sample values. The arrays are used with helper class Calculus to denote accepted "function signatures" when* initializing column FunctionEntry::Signature of table Calculus::Functions.
Each static field of this class represents a permutation of function arguments. Note, that only those permutations which are needed and used by the built-in compiler plugins ( Arithmetics, Math, Strings and DateAndTime ) are contained here.
Custom compiler plug-ins may use the argument signatures given here, if a fitting signature is already included. Otherwise a custom signature array has to be defined, initialized and provided to the function definition table.
