Detailed Description

Base class for dag.

This is the base class for Directed Acyclic Graph : addArc may throw a DirectedCycle if any (directed) cycle is created by this arc.

exemple de code: // creating empty graphs

gum::DAG g1,g2;

// adding nodes and arcs to g1

gum::NodeId i1=g1.addNode();

gum::NodeId i2=g1.addNode();

gum::NodeId i3=g1.addNode();

g1.addArc( i1,i2 );

g1.addArc( i1,i3 );

g1.addArc( i2,i3 );

//throw an InvalidNode

// g1.addArc( i1+i2+i3,i1 );

// throw an InvalidDirectedCycle

// g1.addArc( i3,i1 );

// copying graphs

gum::DAG g3 = g1;

g2 = g1;

gum::DAG g4=g1;

// check if a graph has no node

if ( g1.empty() ) cerr << "graph g1 is empty" << endl;

// remove all the nodes (as well as their adjacent arcs)

g1.clear();

// remove some arc

g4.eraseArc( Arc ( i1,i3 ) );

// remove node

g2.eraseNode( i2 );

// parse a graph

for ( const auto node : g3.nodes() ) // type of node = gum::NodeId

cerr << node << endl;

for ( const auto& arc= g3.arcs()) // type of arc : gum::Arc&

cerr << iter << endl;

for ( const auto node :g3.parents( gum::NodeId(3) ))

cerr << " - "<<*iter;

cerr<<endl;

// remove all the arcs that are parent of a given node

g3.eraseParents( gum::NodeId(2) );

◆ arcsProperty() [1/2]

template<typename VAL>

ArcProperty< VAL > gum::ArcGraphPart::arcsProperty	(	const VAL &	a,

inherited

a method to create a hashMap of VAL from a set of arcs (using for every arc, say x, the VAL a)

Parameters

a	the default value assigned to each arc in the returned Property
size	an optional parameter enabling to fine-tune the returned Property. Roughly speaking, it is a good practice to have a size equal to half the number of arcs. If you do not specify this parameter, the method will assign it for you.

◆ arcsProperty() [2/2]

template<typename VAL>

ArcProperty< VAL > gum::ArcGraphPart::arcsProperty	(	VAL(*	f )(const Arc &),
		Size	size = 0 ) const

inherited

a method to create a hashMap of VAL from a set of arcs (using for every arc, say x, the VAL f(x))

Parameters

f	a function assigning a VAL to any arc
size	an optional parameter enabling to fine-tune the returned Property. Roughly speaking, it is a good practice to have a size equal to half the number of arcs. If you do not specify this parameter, the method will assign it for you.

◆ asNodeSet()

INLINE NodeSet gum::NodeGraphPart::asNodeSet ( ) const

inherited

returns a copy of the set of nodes represented by the NodeGraphPart

Warning: this function is o(n) where n is the number of nodes. In space and in time. Usually, when you need to parse the nodes of a NodeGraphPart, prefer using
for(const auto n : nodes())

rather than
for(const auto n : asNodeSet())

gum::NodeGraphPart::asNodeSet
NodeSet asNodeSet() const
returns a copy of the set of nodes represented by the NodeGraphPart
Definition nodeGraphPart_inl.h:367
