Graph::Node Class Reference

Detailed Description

This is the base type of each node iterator, thus each kind of node iterator converts to this. More precisely each kind of node iterator should be inherited from the trivial node iterator.

Constructor & Destructor Documentation

Node

(

)

[inline]

Warning:

The default constructor sets the iterator to an undefined value.

Node

(

const Node &

)

[inline]

Copy constructor.

Node

(

Invalid

)

[inline]

This constructor initializes the iterator to be invalid.

See also:

Invalid for more details.

Member Function Documentation

bool operator==

(

Node

)

const [inline]

Two iterators are equal if and only if they point to the same object or both are invalid.

bool operator!=

(

Node

)

const [inline]

See also:

operator==(Node n)

bool operator<

(

Node

)

const [inline]

To allow the use of graph descriptors as key type in std::map or similar associative container we require this.

Note:

This operator only have to define some strict ordering of the items; this order has nothing to do with the iteration ordering of the items.
