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

Member Function Documentation

virtual RWspace RWCollectableInt::binaryStoreSize

(

)

const [inline, virtual]

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.

static RWClassID RWCollectableInt::classIsA

(

)

[static]

Returns the RWClassID of this class.

Reimplemented from RWCollectable.

virtual int RWCollectableInt::compareTo

(

const RWCollectable *

c

)

const [virtual]

Returns the difference between self and the RWCollectableInt pointed to by c.

Reimplemented from RWCollectable.

virtual unsigned RWCollectableInt::hash

(

)

const [virtual]

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

Reimplemented from RWCollectable.

virtual RWClassID RWCollectableInt::isA

(

)

const [virtual]

Returns the unique ID for RWCollectableInt.

Reimplemented from RWCollectable.

virtual bool RWCollectableInt::isEqual

(

const RWCollectable *

c

)

const [virtual]

Returns true if self has the same value as the RWCollectableInt at address c.

Reimplemented from RWCollectable.

virtual RWCollectable* RWCollectableInt::newSpecies

(

)

const [virtual]

Allocates a new object off the heap of the same type as self and returns a pointer to it. You are responsible for deleting the object when done with it.

Reimplemented from RWCollectable.

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.

virtual void RWCollectableInt::restoreGuts

(

RWvistream &

)

[virtual]

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

Reimplemented from RWCollectable.

virtual void RWCollectableInt::saveGuts

(

RWFile &

)

const [virtual]

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

Reimplemented from RWCollectable.

virtual void RWCollectableInt::saveGuts

(

RWvostream &

)

const [virtual]

Writes an object's state to an output stream.

Reimplemented from RWCollectable.
