Type Mapping

大体決まってこんな感じ。

UNO	Ruby	C++	UNO Type Description
void	nil	void	Empty type, used only as method return type and in any.
boolean	TrueClass, FalseClass	sal_Bool	Can be true or false.
byte	Fixnum	sal_Int8	Signed 8-bit integer type (ranging from −128 to 127, inclusive).
short	Fixnum	sal_Int16	Signed 16-bit integer type (ranging from −32768 to 32767, inclusive).
unsigned short	Fixnum	sal_uInt16	Unsigned 16-bit integer type (deprecated).
long	Bignum	sal_Int32	Signed 32-bit integer type (ranging from −2147483648 to 2147483647, inclusive).
unsigned long	Bignum	sal_uInt32	Unsigned 32-bit integer type (deprecated).
hyper	Bignum	sal_Int64	Signed 64-bit integer type (ranging from −9223372036854775808 to 9223372036854775807, inclusive).

char	Runo::Char	sal_Unicode	Represents individual Unicode characters (more precisely: individual UTF-16 code units).
string	String	rtl::OUString	Represents Unicode strings (more precisely: strings of Unicode scalar values).
type	Runo::Type	com::sun::star ::uno::Type	Meta type that describes all UNO types.
any	Runo::Any	com::sun::star ::uno::Any	Special type that can represent values of all other types.
