◆ fastPrototype()

template<typename GUM_SCALAR >

InfluenceDiagram< GUM_SCALAR > gum::InfluenceDiagram< GUM_SCALAR >::fastPrototype	(	const std::string &	dotlike,
		Size	domainSize = `2`
	)

static

Create an Influence Diagram with a dot-like syntax which specifies:

the structure "a->*b->$c;b->d<-*e;".
the prefix of a variable can be :
- nothing : chance node (a,d)
- * : decision node (*b)
- $ : utility node ($c) *
the type of the chance or decision variables with different syntax:
- by default, a variable is a gum::RangeVariable using the default domainSize (second argument)
- with "a[10]", the variable is a gum::RangeVariable using 10 as domainSize (from 0 to 9)
- with "a[3,7]", the variable is a gum::RangeVariable using a domainSize from 3 to 7
- with "a[1,3.14,5,6.2]", the variable is a gum::DiscretizedVariable using the given ticks (at least 3 values)
- with "a{top|middle|bottom}", the variable is a gum::LabelizedVariable using the given labels.

Note that if the dot-like string contains such a specification more than once for a variable, the first specification will be used.

Parameters

dotlike	the string containing the specification
domainSize	the default domain size for chance and decision variables

Returns: the resulting influence diagram
