Detailed Description

Collectable integers. Inherits from classes RWInteger and RWCollectable. This class is useful when integers are used as keys in the "dictionary" collection classes, or if integers are stored and retrieved as RWCollectable instances.

The virtual functions of the base class RWCollectable have been redefined.

Synopsis

typedef RWCollectableInt Integer;  // Smalltalk typedef

Constructor & Destructor Documentation

RWCollectableInt() [1/2]

RWCollectableInt::RWCollectableInt

(

)

Calls the appropriate base class constructor. See RWInteger::RWInteger().

RWCollectableInt() [2/2]

RWCollectableInt::RWCollectableInt ( int j )

inline

Calls the appropriate base class constructor. See RWInteger::RWInteger(int).

~RWCollectableInt()

virtual RWCollectableInt::~RWCollectableInt ( )

virtual

Empty destructor.

Member Function Documentation

binaryStoreSize()

virtual RWspace RWCollectableInt::binaryStoreSize ( ) const

inlinevirtual

Returns the number of bytes used by the virtual function saveGuts(RWFile&) to store an object. Typically, this involves adding up the space required to store all primitives, plus the results of calling recursiveStoreSize() for all objects inheriting from RWCollectable. See the Essential Tools Module User's Guide for details.

Reimplemented from RWCollectable.

classIsA()

static RWClassID RWCollectableInt::classIsA ( )

static

Returns the RWClassID of this class.

compareTo()

virtual int RWCollectableInt::compareTo ( const RWCollectable * c ) const

virtual

If c is an RWCollectableInt, returns the difference between self and c, otherwise returns a nonzero value based on the type of c.

Reimplemented from RWCollectable.

copy()

virtual RWCollectable * RWCollectableInt::copy ( ) const

virtual

Returns a new, copy-constructed object of the same type as self. The caller is responsible for deleting the object.

Reimplemented from RWCollectable.

hash()

virtual unsigned RWCollectableInt::hash ( ) const

virtual

Returns the value of RWCollectableInt as an unsigned, to be used as a hash value.

Reimplemented from RWCollectable.

isA()

virtual RWClassID RWCollectableInt::isA ( ) const

virtual

Returns the unique ID for RWCollectableInt.

Reimplemented from RWCollectable.

isEqual()

virtual bool RWCollectableInt::isEqual ( const RWCollectable * t ) const

virtual

Behaves as if compareTo(t) was invoked, returning true if the result equals 0, false otherwise.

Reimplemented from RWCollectable.

newSpecies()

virtual RWCollectable * RWCollectableInt::newSpecies ( ) const

virtual

Returns a new, default-constructed object of the same type as self. The caller is responsible for deleting the object.

Reimplemented from RWCollectable.

restoreGuts() [1/2]

virtual void RWCollectableInt::restoreGuts ( RWFile & )

virtual

Reads an object's state from a binary file, using class RWFile, replacing the previous state.

Reimplemented from RWCollectable.

restoreGuts() [2/2]

virtual void RWCollectableInt::restoreGuts ( RWvistream & )

virtual

Reads an object's state from an input stream, replacing the previous state.

Reimplemented from RWCollectable.

saveGuts() [1/2]

virtual void RWCollectableInt::saveGuts ( RWFile & ) const

virtual

Writes an object's state to a binary file, using class RWFile.

Reimplemented from RWCollectable.

saveGuts() [2/2]

virtual void RWCollectableInt::saveGuts ( RWvostream & ) const

virtual

Writes an object's state to an output stream.

Reimplemented from RWCollectable.
