Typedef Documentation

typedef MUP_BYTECODE_TYPE mu::bytecode_type

The bytecode type used by the parser.

The bytecode type depends on the value_type.

typedef string_type::value_type mu::char_type

The character type used by the parser.

Depends on wether UNICODE is used or not.

typedef value_type*(* mu::facfun_type)(const char_type *, void *)

Callback used for variable creation factory functions.

typedef value_type(* mu::fun_type0)()

Callback type used for functions without arguments.

typedef value_type(* mu::fun_type1)(value_type)

Callback type used for functions with a single arguments.

typedef value_type(* mu::fun_type2)(value_type, value_type)

Callback type used for functions with two arguments.

typedef value_type(* mu::fun_type3)(value_type, value_type, value_type)

Callback type used for functions with three arguments.

typedef value_type(* mu::fun_type4)(value_type, value_type, value_type, value_type)

Callback type used for functions with four arguments.

typedef value_type(* mu::fun_type5)(value_type, value_type, value_type, value_type, value_type)

Callback type used for functions with five arguments.

typedef std::map<string_type, ParserCallback> mu::funmap_type

Container for Callback objects.

typedef int(* mu::identfun_type)(const char_type *sExpr, int *nPos, value_type *fVal)

Callback used for functions that identify values in a string.

typedef char mu::MAP_TYPE_CANT_BE_UNSIGNED[sizeof(STATIC_ASSERTION_FAILURE< bytecode_type(-1)< 0 >)]

This is a static typecheck.

If you get a compiler error here you tried to use an unsigned bytecode map type!

typedef value_type(* mu::multfun_type)(const value_type *, int)

Callback type used for functions with a variable argument list.

typedef value_type(* mu::strfun_type1)(const char_type *)

Callback type used for functions taking a string as an argument.

typedef value_type(* mu::strfun_type2)(const char_type *, value_type)

Callback type used for functions taking a string and a value as arguments.

typedef value_type(* mu::strfun_type3)(const char_type *, value_type, value_type)

Callback type used for functions taking a string and two values as arguments.

typedef MUP_STRING_TYPE mu::string_type

The stringtype used by the parser.

Depends on wether UNICODE is used or not.

typedef std::basic_stringstream<char_type, std::char_traits<char_type>, std::allocator<char_type> > mu::stringstream_type

Typedef for easily using stringstream that respect the parser stringtype.

typedef std::map<string_type, std::size_t> mu::strmap_type

Type for assigning a string name to an index in the internal string table.

typedef std::map<string_type, value_type> mu::valmap_type

Type used for storing constants.

typedef MUP_BASETYPE mu::value_type

The numeric datatype used by the parser.

Normally this is a floating point type either single or double precision.

typedef std::map<string_type, value_type*> mu::varmap_type

Type used for storing variables.
