Detailed Description

A node belongs to either a directed or undirected graph.

Directed graphs are composed of DNode objects, while an undirected graph is composed of UNode objects.

Attention

A node can only be created by an AbstractGraph derived object or from a Nodes container.

Member Function Documentation

attr() [1/2]

const Value & evoplex::BaseNode::attr ( int  id ) const

inline

Gets the value of the attribute at id.

Parameters

id	The attribute's id.

Exceptions

std::out_of_range

if the id is not present.

attr() [2/2]

Value evoplex::BaseNode::attr ( const QString &  name, Value  defaultValue = Value()  ) const

inline

Gets the value corresponding to name.

Parameters

name	The attribute's name.
defaultValue	A Value to be returned if name is not present.

randNeighbour()

Node evoplex::BaseNode::randNeighbour

(

PRG *

prg

)

const

Gets a random neighbour.

Returns an invalid/empty Node if the node has no neighbours.

setAttr()

void evoplex::BaseNode::setAttr ( int  id, const Value &  value  )

inline

Sets the value at id.

Parameters

id	The attribute's id.
value	The new attribute's value.

Exceptions

std::out_of_range

if the id is not present.
