Detailed Description

Integer class. This class is useful as a base class for classes that use integers as keys in dictionaries, and so forth.

Synopsis

#include <rw/rwint.h>
RWInteger i;

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&);

RWInteger::operator int ( ) const

inline

Type conversion to int.

int RWInteger::value ( void  ) const

inline

Returns the value of the RWInteger.

int RWInteger::value ( int  newval )

inline

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

Outputs x to std::ostream o.

RWvostream & operator<< ( RWvostream &  str, const RWInteger &  x  )

Saves the RWInteger x to a virtual stream.

RWFile & operator<< ( RWFile &  file, const RWInteger &  x  )

Saves the RWInteger x to an RWFile.

std::istream& operator>> ( std::istream &  i, RWInteger &  x  )
