Public Member Functions
virtual void	generate_model (std::vector< double > parameters)=0
	A user-supplied one-time generate function that permits model construction prior to calling the visibility_amplitude for each datum. Takes a vector of parameters.
virtual size_t	size () const =0
	A user-supplied function that returns the number of the parameters the model expects.
virtual double	visibility_amplitude (datum_visibility_amplitude &d, double accuracy)=0
	A user-supplied function that returns the visibility amplitude in Jy. Takes a datum_visibility_amplitude to provide access to the various accoutrements. While this provides access to the actual data value, the two could be separated if necessary. Also takes an accuracy parameter with the same units as the data, indicating the accuracy with which the model must generate a comparison value.
virtual void	set_mpi_communicator (MPI_Comm comm)
	Defines a set of processors provided to the model for parallel computation via an MPI communicator. Only facilitates code parallelization if the model computation is parallelized via MPI.

Protected Attributes
MPI_Comm	_comm

Detailed Description

To facilitate model-data comparisons, here a fixed interface that may be assumed by likelihoods, etc., for generating model visibility amplitude data is defined. All models that produce visibility amplitude data should be child classes of model_visibility_amplitude, thereby inheriting this interface. The key function is visibility_amplitude which takes a datum_visibility_amplitude, providing access to all of the relevant accoutrements of a data point, and an accuracy parameter, and returns the model visibility amplitude.

Warning

This class contains multiple purely virtual functions, making it impossible to generate an explicit instantiation.
