Detailed Description

An iterator class defining basic operations to iterate the Relation objects in a Structure.

This iterator class encapsules the internal form of Relation storage in a Structure. By using this iterator class, which is what you have to do, you are safe from changes in implementation detail as the container used to store Relation objects. Additionally it is the prefered way to make a visit to each Relation in a Structure.

Constructor & Destructor Documentation

Arxx::Structure::const_iterator::const_iterator

(

std::map< std::string, Arxx::Structure::Relation >::const_iterator

iRelation

)

The constructor of a const Relation iterator.

Parameters:

iRelation

The STL iterator from the Structure's aggregated Relation container. The internal representation of the iterator.

This constructor creates a const Relation iterator from an STL iterator.

Arxx::Structure::const_iterator::const_iterator

(

Arxx::Structure::iterator

iRelation

)

The constructor of a const Relation iterator from a non-const Relation iterator.

Parameters:

iRelation

The Relation iterator from the Structure's aggregated Relation container.

This constructor creates a const Relation iterator from a non-const Relation iterator.

Arxx::Structure::const_iterator::~const_iterator

(

void

)

The destructor of a const Relation iterator.

Member Function Documentation

const Arxx::Structure::Relation & Arxx::Structure::const_iterator::operator *

(

void

)

const

This will return the Arxx::Relation that this iterator points to.

This is the const version of the operator*() thus the returned Relation is const as well.

bool Arxx::Structure::const_iterator::operator!=

(

const Arxx::Structure::const_iterator &

iRelation

)

const

Tests two iterators for inequality.

Parameters:

iRelation

The iterator to check against.

Arxx::Structure::const_iterator & Arxx::Structure::const_iterator::operator++

(

void

)

Advances the iterator.

Advances the Relation iterator. It is not defined which will be the next Relation the iterator points to. It is only assured that every Relation in the Structure will be passed once.

const Arxx::Structure::Relation * Arxx::Structure::const_iterator::operator->

(

void

)

The Relation accessor.

bool Arxx::Structure::const_iterator::operator==

(

const Arxx::Structure::const_iterator &

iRelation

)

const

Tests two iterators for equality.

Parameters:

iRelation

The iterator to check against.
