Digraph::Node Class Reference

Detailed Description

This class identifies a node of the digraph. It also serves as a base class of the node iterators, thus they will convert to this type.

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 digraph 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.
