Detailed Description

This contains all the information we want for a node in a DFSTree.

Several rules are used regarding nodes in Pattern::graph. First nodes are added respecting a depth-first search, thus each node is labelled from 1 to n, where n is the number of nodes in Pattern::graph.

Given two nodes id i and j, if i < j then i was discovered before j in the depth first search.

To retrieve the depth first search tree from Pattern::graph simple consider only arcs (u, v) with u < v. The set of arcs { (u,v) | u < v} is called the forward edge set and the set of arcs { (u,v) | u > v} is called the backward edge set.

The orientation in Pattern::graph is only used to differentiate forward edges from backward edges.

arcsProperty() [1/2]

template<typename VAL >

ArcProperty< VAL > gum::ArcGraphPart::arcsProperty ( VAL(*)(const Arc &)  f, 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.

arcsProperty() [2/2]

template<typename VAL >

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

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()) 

as this is faster and consumes much less memory.
