GraphIncIt< GR, Item, Base, sel > Class Template Reference

---

Detailed Description

template<typename GR, typename Item = typename GR::Arc, typename Base = typename GR::Node, char sel = '0'>
class lemon::concepts::GraphIncIt< GR, Item, Base, sel >

This class describes the concept of InArcIt, OutArcIt and IncEdgeIt subtypes of digraph and graph types.

Note:

Since these iterator classes do not inherit from the same base class, there is an additional template parameter (selector) sel. For InArcIt you should instantiate it with character 'i', for OutArcIt with 'o' and for IncEdgeIt with 'e'.

Constructor & Destructor Documentation

GraphIncIt

(

)

[inline]

Default constructor.

Warning:

The default constructor is not required to set the iterator to some well-defined value. So you should consider it as uninitialized.

GraphIncIt

(

const GraphIncIt< GR, Item, Base, sel > &

it

)

[inline]

Copy constructor.

GraphIncIt	(	const GR &	,
		const Base &
	)			[inline, explicit]

Constructor that sets the iterator to the first arc incoming to or outgoing from the given node.

GraphIncIt

(

Invalid

)

[inline]

Constructor for conversion from INVALID. It initializes the iterator to be invalid.

See also:

Invalid for more details.

Member Function Documentation

GraphIncIt& operator=

(

const GraphIncIt< GR, Item, Base, sel > &

)

[inline]

Assignment operator for the iterator.

GraphIncIt& operator++

(

)

[inline]

This operator increments the iterator, i.e. assigns it to the next arc incoming to or outgoing from the given node.

bool operator==

(

const GraphIncIt< GR, Item, Base, sel > &

)

const [inline]

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

bool operator!=

(

const GraphIncIt< GR, Item, Base, sel > &

)

const [inline]

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