RWInteger(3C++)

Name
     RWInteger - Rogue Wave library class

Synopsis
              #include <rw/rwint.h>



              RWInteger i;




Description
     Integer class.  This class is useful as a base class for classes that use
     integers as keys in dictionaries, etc.

Persistence
     Isomorphic

Public Constructors
              RWInteger();


     Construct an RWInteger with value zero (0).

              RWInteger(int i);


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

Type Conversion
              operator
          int();


     Type conversion to int.

Public Member Functions
              RWspace
          binaryStoreSize() const;


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

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


     Returns the value of the RWInteger.

              int
          value(int newval);


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

Related Global Operators
              ostream&
          operator<<(ostream& o, const RWInteger& x);


     Output x to ostream o.

              istream&
          operator>>(istream& i, RWInteger& x);


     Input x from istream i.

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


     Saves the RWInteger x to a virtual stream or RWFile, respectively.

              RWvistream&
          operator>>(RWvistream&, RWInteger& x);
          RWFile&
          operator>>(RWFile&,     RWInteger& x);


     Restores an RWInteger into x from a virtual stream or RWFile,
     respectively, replacing the previous contents of x.
