Constructor & Destructor Documentation

Node

(

)

[inline]

Default constructor.

Warning:

It sets the object to an undefined value.

Node

(

const Node &

)

[inline]

Copy constructor.

Node

(

Invalid

)

[inline]

Initializes the object to be invalid.

See also:

Invalid for more details.

Member Function Documentation

bool operator==

(

Node

)

const [inline]

Equality operator.

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

bool operator!=

(

Node

)

const [inline]

Inequality operator.

bool operator<

(

Node

)

const [inline]

Artificial ordering operator.

Note:

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