Detailed Description

The edge struct represents an edge in a Graph object.

This structure only contains an identifier, and a function to check if the edge is valid. A edge is considered invalid when its id has the UINT_MAX value.

Most operations performed on an edge (getting the source, target, etc) are available into the tlp::Graph object.

Constructor & Destructor Documentation

tlp::edge::edge

(

)

[inline]

edge creates an invalid edge.

Definition at line 48 of file Edge.h.

tlp::edge::edge

(

unsigned int

j

)

[inline, explicit]

edge Create an edge of given identifier. It is your responsibility to make sure an edge of this ID exists when you create the edge. If you want to make sure this edge exists, use Graph::isElement(), as isValid() will only tell is the edge was correctly initialized.

Parameters:

j	the identifier this edge will use.

Member Function Documentation

bool tlp::edge::isValid

(

)

const [inline]

isValid checks if the edge is valid. An invalid edge is an edge whose id is UINT_MAX.

Returns:

whether the edge is valid or not.

Definition at line 90 of file Edge.h.

tlp::edge::operator unsigned int

(

)

const [inline]

operator unsigned int A convenience function to get the id of an edge.

Definition at line 62 of file Edge.h.

bool tlp::edge::operator!=

(

const edge

e

)

const [inline]

operator != Compares two edges, checking that they are identical.

Parameters:

n	The other edge to compare this one to.

Returns:

Whether or not the two edges are the same.

Definition at line 80 of file Edge.h.

bool tlp::edge::operator==

(

const edge

e

)

const [inline]

operator != Compares two edges, checking that they are different..

Parameters:

n	The other edge to compare this one to.

Returns:

Whether or not the two edges are different.
