Detailed Description

Abstacts a set of iteration quantities for an iterative algorithm.

This object encapsulates a set of iteration quantity access objects. The concrete types of the IterQuantity objects are expected to be subclasses of IterQuantityAccess. It is therefore up the the clients to determine the concrete types of these iteration quantity access objects and to use dynamic_cast<...> (or static_cast<...> if you are sure) to access the IterQuantityAccess<...> object and therefore the iteration quantities themselves. Each iteration quantity (IQ) access object must have a unique name associated with it. IQ objects are given to the state object by clients through the set_iter_quant() method at which point the IQ object will be given a unique id that will never change change until the IQ object is removed using erase_iter_quant(). Memory management is performed using the Teuchos::RCP smart reference counting poiner class. The id of any IQ object (iq_id) can be obtained from its name by calling iq_id = get_iter_quant_id(iq_name). If an IQ object with the name iq_name does not exist then get_iter_quant_id(iq_name) will return DOES_NOT_EXIST. The IQ objects themselves can be accesed in O(log(num_iter_quant())) time using iter_quant(iq_name) or in O(1) time using iter_quant(iq_id). Therefore, the access of IQ objects using iq_id is an optimization for faster access and the client should never have to lookup iq_name given iq_id. The mapping only works from iq_name to iq_id, not the other way around. It is guaranteed that as long as erase_iter_quant(iq_id) is not called that each iq_id that &iter_quant(iq_id) == &iter_quant( get_iter_quant(iq_name) ) will true. For iq_name, if get_iter_quant_id(iq_name) == DOES_NOT_EXIST then iter_quant(iq_name) will throw the exception DoesNotExist.

The next_iteration() operation is called by the algorithm to call next_iteration() on each of the IQ objects.

The dump_iter_quant(out) operation prints out a list of all of the IQ objects of thier iq_name, iq_name and concrete type.

The default copy constructor, and assignment operator functions are allowed since they have the proper semantics.

size_t IterationPack::AlgorithmState::num_iter_quant ( ) const

Return the number of iteration quantities.

AlgorithmState::iq_id_type IterationPack::AlgorithmState::set_iter_quant	(	const std::string &	iq_name,
		const IQ_ptr &	iq
	)

virtual

Inserts the iteration quantity through a RCP<...> object.

Time = O(log(num_iter_quant)), Space = O(1).

If an iteration quantity already exists with the name iq_name then a AlreadyExists exception will be thrown. Otherwise the function will return the iq_id assigned to the inserted interation quantity.

Preconditions:

iq.get() != NULL (thorw std::invalid_argument)
get_iter_quant_id(iq_name) == DOES_NOT_EXIST (throw AlreadyExists)

Definition at line 61 of file IterationPack_AlgorithmState.cpp.

void IterationPack::AlgorithmState::erase_iter_quant ( const std::string & iq_name )

virtual

Removes the iteration quantity with name iq_name.

Time = O(log(num_iter_quant)), Space = O(1).

If get_iter_quant(iq_name).count() == 1 then the IterQuantity object pointed to will be deleted. Subsequently, the iq_id returned from set_iter_quant(...) when iq_name was set is no longer valid.

Preconditions:

get_iter_quant_id(iq_name) != DOES_NOT_EXIST (throw DoesNotExist)

Definition at line 80 of file IterationPack_AlgorithmState.cpp.

AlgorithmState::iq_id_type IterationPack::AlgorithmState::get_iter_quant_id ( const std::string & iq_name ) const

inlinevirtual

Return the iteration quantity id (iq_id) for the iteration quantity.

If an iteration quantity with the name iq_name does not exist, then the value DOES_NOT_EXIST is returned.

Time = O(log(num_iter_quant)), Space = O(1).

Definition at line 323 of file IterationPack_AlgorithmState.hpp.

AlgorithmState::IQ_ptr & IterationPack::AlgorithmState::get_iter_quant ( iq_id_type iq_id )

inlinevirtual

Returns the RCP<...> for the iteration quantiy with iq_id.

If this iq_id does not correspond to a valid iteration quantity object then a DoesNotExist exception will be thrown. If iq_id was returned from get_iter_quant_id(iq_name), this iq_id may become invalid if a client called erase_iter_quant(iq_name) in the mean time.

Time = O(1), Space = O(1).
