Detailed Description

template<typename GUM_SCALAR>
class gum::BayesNetFactory< GUM_SCALAR >

A factory class to ease BayesNet construction.

A BayesNetFactory will never create a BayesNet and works on only one BayesNet.

The only exception of this behaviour is when you create a copy of the factory, it will create a copy of it's BayesNet. This is useful if you want to create two BayesNet sharing a common base.

However be very careful because the copy will not delete it's BayesNet.

Each method will raise an OperationNotAllowed if you call it when the factory is not in a valid state for that call. The error message is "Illegal state.".

Member Enumeration Documentation

factory_state

enum gum::IBayesNetFactory::factory_state : char

stronginherited

The enumeration of states in which the factory can be in.

Every documentation section's name indicates from which state you can call it's methods, and in which state it places the factory.

There is an exception for the delegated CPT definition methods which do not change the state of the factory.

BayesNetFactory() [1/2]

template<typename GUM_SCALAR >

INLINE gum::BayesNetFactory< GUM_SCALAR >::BayesNetFactory ( BayesNet< GUM_SCALAR > *  bn )

explicit

Use this constructor if you want to use an already created BayesNet.

Parameters

bn	A pointer over the BayesNet filled by this factory.

Exceptions

DuplicateElement

Raised if two variables in bn share the same name.

template<typename GUM_SCALAR >

(

Copy constructor.

The copy will have an exact copy of the constructed BayesNet in source.

Warning

You can only copy a factory if its current state is NONE or NETWORK.

Exceptions

OperationNotAllowed

Raised if the state of source is not NONE or NETWORK.

Destructor.

To prevent strange behaviour you should always destroy a BayesNetFactory when it's state equals NONE.

Exceptions

FatalError

Raised if the state of the factory prevents it to die peacefully.

Define a variable's CPT.

You can only call this method if the factory is in the NONE or NETWORK state.

Be careful that table is given to the built BayesNet, so it will be deleted with it, and you should not directly access it after you call this method.

When the redefineParents flag is set to true the constructed BayesNet's DAG is changed to fit with table's definition.

Parameters

varName	The name of the concerned variable.
table	A pointer over the CPT used for var.
redefineParents	If true redefine var's parents to match table's variables set.

Exceptions

INLINE void gum::BayesNetFactory< GUM_SCALAR >::setVariableCPTImplementation ( MultiDimAdressable *  adressable )

finalvirtual

Defines the implementation to use for var's Potential.

Warning

The implementation must be empty.

The pointer is always delegated to var's Potential! No copy of it is made.

Todo:

When copy of a MultiDimImplementation is available use a copy behaviour for this method.

Exceptions

NotFound	Raised if no variable matches var.
OperationNotAllowed	Raised if impl is not empty.
OperationNotAllowed	If an implementation is already defined for the current variable.

template<typename GUM_SCALAR >

INLINE void gum::BayesNetFactory< GUM_SCALAR >::setVariableValuesUnchecked ( const std::vector< float > &  values )

finalvirtual

Gives the values of the variable with respect to precedent parents modality.

If some parents have no modality set, then we apply values for all instantiations of that parent.

This means you can declare a default value for the table by doing

BayesNetFactory factory;
// Do stuff
factory.startVariableDeclaration();
factory.variableName("foo");
factory.endVariableDeclaration();
factory.startParentsDeclaration("foo");
// add parents
factory.endParentsDeclaration();
factory.startFactorizedProbabilityDeclaration("foo");
std::vector<double> seq;
seq.insert(0.4); // if foo true
seq.insert(O.6); // if foo false
factory.setVariableValues(seq); // fills the table with a default value
// finish your stuff
factory.endFactorizedProbabilityDeclaration();

as for rawProba, if value's size is different than the number of modalities of the current variable, we don't use the supplementary values and we fill by 0 the missing values.
