Detailed Description

A projection class that does exactly what we need when generating projections when testing a generator.

This is initialized containing nothing and can iteratively return projections by calling next(). This first goes a through a list of sequential projections and then gives a list of projections with non sequential indices.

When iterating through this object, it returns LatticeTester::Coordinates objects. These contain coordinates starting from 0 to be used when accessing elements in vectors. Take care, some of the functions in this objects take integers starting at 1 that are transformed by the object.

Constructor & Destructor Documentation

Projections()

LatMRG::Projections::Projections	(	int	dimProj,
		int	minDim,
		std::vector< int > &	projDim
	)

Creates a Projections set.

It is necessary that dimProj == length(projDim).

This set will contain projections with sequential indices in dimensions minDim to projDim[0]+1. That means the projections will include sets {0, ..., minDim-1} through {0, ..., projDim[0]}.

When the length of projDim is greater than 1, this set will contain non sequential projections in dimensions 2 through dimProj. Projections in dimension i use i indices in the range [0, projDim[i-1]] with at least one of them at least minDim-1.

Member Function Documentation

end()

bool LatMRG::Projections::end

(

int

dim = 0

)

If dim==0 this will return true if this calling next will not get a new projection.

If dim==1 this will return true if the current projection dimension is over.

getDim()

int LatMRG::Projections::getDim

(

)

Returns the dimension of the current projections.

This does not return the value of m_currentDim

getProj()

LatticeTester::Coordinates LatMRG::Projections::getProj

(

)

Returns the current projection the object is at.

maxDim()

int LatMRG::Projections::maxDim ( )

inline

minDim()

int LatMRG::Projections::minDim ( )

inline

next()

LatticeTester::Coordinates LatMRG::Projections::next

(

)

This returns the next projection for this set of projections.

If this object is not initialized, this fills it with the first projection with indices from 0 to m_minDim-1. It then adds coordinates up to m_projDim[0]. It then returns coordinates

numProj()

int LatMRG::Projections::numProj ( )

inline

operator++()

LatticeTester::Coordinates LatMRG::Projections::operator++

(

)

Returns the result of next().

This is for convenience.

projDim()

std::vector<int>& LatMRG::Projections::projDim ( )

inline

resetDim()

void LatMRG::Projections::resetDim

(

int

dim = 0

)

toString()

std::string LatMRG::Projections::toString

(

)

Returns a string describing this object of the form.

Sequential: minDim to m_projDim[0]+1
Projections Dimension                  i
            Coordinates m_projDim[i-1]+1
