Detailed Description

template<typename GUM_SCALAR>
class gum::prm::PRMFactory< GUM_SCALAR >

Factory which builds a PRM<GUM_SCALAR>.

The Factory always create one PRM<GUM_SCALAR> which is not deleted with the factory, so be very careful to delete the PRM<GUM_SCALAR> built by this factory.

The factory does not allow any sequence of calls, if you call a method when the factory is in an incoherent state it will raise a FactoryInvalidState exception.

Keep in mind that most methods could raise gum::FatalError if something unexpected happens, since the framework is meant to evolve it is possible.

template<typename GUM_SCALAR >

INLINE PRMType * gum::prm::PRMFactory< GUM_SCALAR >::_retrieveCommonType_ ( const std::vector< PRMClassElement< GUM_SCALAR > * > &  elts )

private

Retrieve the common PRMType of a vector of PRMClassElement<GUM_SCALAR>.

The vector elts must only contains PRMClassElement<GUM_SCALAR> with a PRMType, i.e. PRMAttribute<GUM_SCALAR>, PRMAggregate and PRMSlotChain<GUM_SCALAR>. If not a WrongClassElement is raised.

A common PRMType is PRMType t such as t.isSuperTypeOf(elts[i]) for 0 < i < elts.size(), where elts is a PRMType container.

Parameters

elts	A vector of PRMClassElement<GUM_SCALAR>.

Returns

Returns the common super PRMType of all PRMClassElement<GUM_SCALAR> un elts.

Exceptions

WrongClassElement	Raised if elts contains a PRMClassElement<GUM_SCALAR> without a PRMType.
NotFound	Raised if there exists no common super type of all PRMClassElement<GUM_SCALAR> in elts.

private

Retrieve inputs for an PRMAggregate.

The vector chains contains names of the PRMAggregate inputs. If a name does not match an existing PRMClassElement<GUM_SCALAR> in c, then a call to PRMFactory:: buildSlotChains() is made. Such created PRMSlotChain<GUM_SCALAR> are added to c.

Parameters

c	The class in which the PRMAggregate is defined.
chains	Vector of the PRMAggregate inputs names.
inputs	Vector filled with the PRMClassElement<GUM_SCALAR> matching the names in chains.

Returns

true if there was at least one slotchain in chains.

Exceptions

NotFound

Raised if a name in chains does not match a legal PRMSlotChain<GUM_SCALAR> or an existing PRMClassElement<GUM_SCALAR> in c.

INLINE PRMType * gum::prm::PRMFactory< GUM_SCALAR >::_retrieveType_ ( const std::string &  name ) const

Returns a pointer on a PRMType given it's name. Since the type can be given either with it's local name (without the prefix), full name (with the prefix) or can come from an import unit, or maybe one day with a using declaration we need some processing to find it.

The following precedences on finding the name is used:

• name
• prefix.name
• import_1.name
• import_2.name
• ...
• import_N.name In the case a local name is used multiple time, it's preferable to use it's full name.

  Exceptions

  OperationNotAllowed

  If the type is undeclared.

This used by PRMFactory:: retrieveCommonType. This returns 0 if t does not have a super type.

Parameters

t	The PRMType for which we compute its depth.

Returns

Returns the depth of t.

addAggregator()

template<typename GUM_SCALAR >

INLINE void gum::prm::PRMFactory< GUM_SCALAR >::addAggregator ( const std::string &  name, const std::string &  agg_type, const std::vector< std::string > &  chains, const std::vector< std::string > &  params, std::string  type = ""  )

overridevirtual

Add an aggregator in the current declared class.

If at least one parent of an aggregator is a PRMSlotChain<GUM_SCALAR>, then all of it's parents must be PRMSlotChain<GUM_SCALAR>. When an aggregator parents are only composed of PRMAttribute<GUM_SCALAR> and PRMAggregate, then it is directly added as an PRMAttribute<GUM_SCALAR> to it's Class<GUM_SCALAR>.

Parameters

name	The name of this aggregator.
agg_type	The name of the aggregator type of this aggregator.
chains	The set of chains on which this aggregate applies.
params	The list of parameters for this aggregator.
type	Some aggregators have a user defined type, use this parameter to define it.

Exceptions

OperationNotAllowed	Raised if one or more parameters misses or are not correct.
TypeError	Raised if the aggregator's type or one or more of the chains are not of the good type.

template<typename GUM_SCALAR >

INLINE void gum::prm::PRMFactory< GUM_SCALAR >::addAttribute ( PRMAttribute< GUM_SCALAR > *  attr )

virtual

Add an already created attribute to the current class.

Use this method when you must add functions, such as Noisy-Or.

Use this method when you need to add functions, such as Noisy-Or. The attribute CPT is checked for parents and arcs will be added using the DiscreteVariable pointers, thus be careful to use those of the attributes, aggregates and slotchains of the current class. gum::prm::Class<GUM_SCALAR>::insertArc() will be called for each found parent of attr, so you should overload gum::prm::PRMAttribute<GUM_SCALAR>::addParent() to prevent duplication errors. Such class exists: gum::prm::PRMFuncAttribute .

The pointer is given to the class, so do not worry about deleting it.

Parameters

attr	The attribute added to the current class.

Exceptions

NotFound

Raised if one of the DiscreteVariable in attr CPT does not match any PRMClassElement<GUM_SCALAR> in this.

addImport()

template<typename GUM_SCALAR >

INLINE void gum::prm::PRMFactory< GUM_SCALAR >::addImport ( const std::string &  name )

overridevirtual

Add an import for namespace lookup.

When loading a module, you should push all import declarations using this method. The order in which you add imports will impact name resolution (first found, first used).

Imports are sync with packages: when you push a new package a new empty list of imports is added. When you pop a package the current list of imports is discarded and the previous one is restored.

Parameters

name	The name of the package for all further objects.

Add a compound noisy-or as an PRMAttribute<GUM_SCALAR> to the current Class<GUM_SCALAR>.

The type of a noisy-or must be a boolean.

Parameters

name	the name of the PRMAttribute<GUM_SCALAR> added as a noisy-or.
chains	the list of parents of the noisy-or.
numbers	the list of weights for each parent. Can consist of only one value which will be applied to all the parents.
leak	the leak
label	the label on which the noisy-or applies, can be an empty string (the noisy-or will behave as if chains are all booleans).

Exceptions

NotFound	Raised if one of the chains or the label is not found.
FactoryInvalidState	Raised if a Class<GUM_SCALAR> is not the current declared PRMObject.
OperationNotAllowed	Raised if for some reasons the parameters are invalid.

The creation of the CPF is left to the factory because we do not know what level of complexity for CPF implementation can be handled by the PRM<GUM_SCALAR> implementation.

How to fill a CPT? If you want to fill the CPT of P(A|B,C) with A, B and C boolean variables ( {f, t}, the order is important), then the following array is valid:

[0.20, 0.80, // P(f|f, f) = 0.20 and P(t|f, f) = 0.80
 0.50, 0.50, // P(f|t, f) = 0.50 and P(t|t, f) = 0.50
 0.70, 0.30, // P(f|f, t) = 0.70 and P(t|f, t) = 0.30
 0.01, 0.99] // P(f|t, t) = 0.01 and P(t|t, t) = 0.99
