Detailed Description

The node struct represents a node in a Graph object.

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

Most operations performed on a node (getting out edges etc) are available into the tlp::Graph object.

Constructor & Destructor Documentation

tlp::node::node ( )
inline

node creates an invalid node.

Definition at line 48 of file Node.h.

tlp::node::node ( unsigned int  j)
inlineexplicit

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

Parameters
jthe identifier this node will use.

Definition at line 57 of file Node.h.

Member Function Documentation

bool tlp::node::isValid ( ) const
inline

isValid checks if the node is valid. An invalid node is a node whose id is UINT_MAX.

Returns
whether the node is valid or not.

+ Here is the caller graph for this function:

tlp::node::operator unsigned int ( ) const
inline

operator unsigned int A convenience function to get the id of a node.

Definition at line 62 of file Node.h.

bool tlp::node::operator!= ( const node  n) const
inline

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

Parameters
nThe other node to compare this one to.
Returns
Whether or not the two nodes are different.

Definition at line 71 of file Node.h.

bool tlp::node::operator== ( const node  n) const
inline

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

Parameters
nThe other node to compare this one to.
Returns
Whether or not the two nodes are the same.
