 RWInteger i;

Persistence

Isomorphic

Constructor & Destructor Documentation

RWInteger::RWInteger

(

int

i = 0

)

[inline]

Constructs an RWInteger with value i. Serves as a type conversion from int.

Note:

If no argument is supplied, the value defaults to zero (0).

Member Function Documentation

RWspace RWInteger::binaryStoreSize

(

)

const [inline]

Returns the number of bytes necessary to store the object using the global function:

RWFile& operator<<(RWFile&, const RWInteger&);

Reimplemented in RWCollectableInt.

RWInteger::operator int

(

)

const [inline]

Type conversion to int.

int RWInteger::value

(

int

newval

)

[inline]

Changes the value of the RWInteger to newval and returns the old value.

int RWInteger::value

(

void

)

const [inline]

Returns the value of the RWInteger.

RWFile & operator<<	(	RWFile &	file,
		const RWInteger &	x
	)			[related]

Saves the RWInteger x to an RWFile.

RWvostream & operator<<	(	RWvostream &	str,
		const RWInteger &	x
	)			[related]

Saves the RWInteger x to a virtual stream.

std::ostream & operator<<	(	std::ostream &	o,
