Typedef Documentation

◆ Cat

typedef QString DynGenPar::Cat

Category type: string or integer depending on DYNGENPAR_INTEGER_CATEGORIES.

If DYNGENPAR_INTEGER_CATEGORIES is defined, this typedef is defined as:

typedef int Cat;

instead.

Definition at line 68 of file dyngenpar.h.

◆ CatArg

typedef const Cat& DynGenPar::CatArg

Category type (string or integer) when passed as an argument.

If DYNGENPAR_INTEGER_CATEGORIES is defined, this typedef is defined as:

typedef int CatArg;

instead.

This typedef is used for maximum efficiency, to pass strings by reference, but integers by value.
