Detailed Description

RWCollectableAssociation inherits class RWCollectable. Used internally to associate a key with a value in the Essential Tools Module "dictionary" collection classes. Comparison and equality testing are forwarded to the key part of the association.

Synopsis

#include <rw/collass.h>

See also

The dictionary containers RWBTreeDictionary, RWHashDictionary, and RWIdentityDictionary make use of RWCollectableAssociation. When any of their content is dealt with as an RWCollectable, such as when operator+=() or asBag() is used, the RWCollectableAssociation is exposed.

Member Function Documentation

binaryStoreSize()

virtual RWspace RWCollectableAssociation::binaryStoreSize ( ) const

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.

classIsA()

static RWClassID RWCollectableAssociation::classIsA ( )

static

Returns the RWClassID of this class.

compareTo()

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

virtual

Returns the results of calling RWCollectable::compareTo().

Reimplemented from RWCollectable.

copy()

virtual RWCollectable * RWCollectableAssociation::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 RWCollectableAssociation::hash ( ) const

virtual

Returns the results of calling key()->hash().

Reimplemented from RWCollectable.

isA()

virtual RWClassID RWCollectableAssociation::isA ( ) const

virtual

Returns the unique ID for RWCollectableAssociation.

Reimplemented from RWCollectable.

isEqual()

virtual bool RWCollectableAssociation::isEqual ( const RWCollectable * c ) const

virtual

Returns the results of calling RWCollectable::isEqual().

Reimplemented from RWCollectable.

key()

RWCollectable * RWCollectableAssociation::key ( ) const

inline

Returns the key part of the association.

newSpecies()

virtual RWCollectable * RWCollectableAssociation::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 RWCollectableAssociation::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 RWCollectableAssociation::restoreGuts ( RWvistream & )

virtual

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

Reimplemented from RWCollectable.

saveGuts() [1/2]

virtual void RWCollectableAssociation::saveGuts ( RWFile & ) const

virtual

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

Reimplemented from RWCollectable.

saveGuts() [2/2]

virtual void RWCollectableAssociation::saveGuts ( RWvostream & ) const

virtual

Writes an object's state to an output stream.

Reimplemented from RWCollectable.

value() [1/2]

RWCollectable * RWCollectableAssociation::value ( ) const

inline

Returns the value part of the association.

value() [2/2]

RWCollectable * RWCollectableAssociation::value

(

RWCollectable *

ct

)

Sets the value to ct and returns the old value.
