Member Function Documentation

erase()

template<typename GUM_SCALAR>

void gum::PartialInstantiationRegister4MultiDim< GUM_SCALAR >::erase	(	const std::string &	instantiation_func_name,
		const std::string &	type_multidim )

Removes a given entry from the register.

Removes the function, if any, that performs the instantiation described by instantiation_func_name, and that takes in argument a multiDim of type type_multidim.

Parameters

instantiation_func_name	The name of the instantiation performed by the function to remove.
type_multidim	The real type of the multiDim taken in argument by the function to remove.

exists()

template<typename GUM_SCALAR>

bool gum::PartialInstantiationRegister4MultiDim< GUM_SCALAR >::exists	(	const std::string &	instantiation_func_name,
		const std::string &	type_multidim ) const

Indicates whether a given entry exists in the register.

Indicates if the register contains a function that performs the instantiation described by instantiation_func_name, and that takes in argument a multiDim of type type_multidim.

Parameters

instantiation_func_name	The name of the instantiation performed by the function we look for.
type_multidim	The real type of the multiDim taken in argument by the function we look for.

Returns

Returns true if a given entry exists in the register.

get()

template<typename GUM_SCALAR>

PartialInstantiationPtr gum::PartialInstantiationRegister4MultiDim< GUM_SCALAR >::get	(	const std::string &	instantiation_func_name,
		const std::string &	type_multidim ) const

Returns the specialized partial instantiation operator assigned to a given type of MultiDimImplementation.

Parameters

instantiation_func_name	describes the name of the partial instantiation performed by the function we look for.
type_multidim	the real type of the multiDim taken in argument by the function we look for

Returns

Returns The function, if any, that performs the partial instantiation described by instantiation_name, and that takes in argument a multiDim of type type_multidim.

Exceptions

NotFound

Raised if the operator we look for does not exist within this register.

insert()

template<typename GUM_SCALAR>

void gum::PartialInstantiationRegister4MultiDim< GUM_SCALAR >::insert	(	const std::string &	instantiation_func_name,
		const std::string &	type_multidim,
		PartialInstantiationPtr	newFunction )

Adds a new entry into the register.

This method inserts a new function (newFunction) taking a multiDim of type type_multidim (which actually inherit from MultiDimImplementation) and a hashTable assigning to some variables their values (actually the index of their values) in arguments. This new function's purpose is to achieve the instantiation of the variables of the hashtable within the multiDim. As such, it returns the table without these variables.

Note that although newFunction actually performs an operation on multiDims of type type_multidim, it should be declared as taking in argument two MultiDimImplementations. This constraint is imposed by the C++ typing system.

Parameters

instantiation_func_name	The name of the instantiation function.
type_multidim	The real type of the multiDim taken in argument by function newFunction.
newFunction	A pointer to the new function to register.

Register()

template<typename GUM_SCALAR>

PartialInstantiationRegister4MultiDim & gum::PartialInstantiationRegister4MultiDim< GUM_SCALAR >::Register ( )

static

A named constructor that constructs one and only one Register per data type.

Note that this constructor prevents the famous init order fiasco.

Member Data Documentation

_set_

template<typename GUM_SCALAR>

HashTable< std::string, PartialInstantiationSet* > gum::PartialInstantiationRegister4MultiDim< GUM_SCALAR >::_set_

private

A mapping from the types of MultiDimImplementations to partial instantiation operators.

In this type, the strings represent the very types of the MultiDimImplementations that will be combined. Hence, to a subtype of MultiDimImplementation is associated a function to partially instantiate this subtype of hypermatrix (the PartialInstantiationPtr).
