Detailed Description

template<typename number = double>
struct AffineConstraints< number >::ConstraintLine

This class represents one constraint in an AffineConstraints object.

Entries

template<typename number = double>

using AffineConstraints< number >::ConstraintLine::Entries = std::vector<std::pair<size_type, number> >

A data type in which we store the list of entries that make up the homogeneous part of a constraint.

Member Function Documentation

operator<()

template<typename number = double>

bool AffineConstraints< number >::ConstraintLine::operator<

(

const ConstraintLine &

)

const

This operator is a bit weird and unintuitive: it compares the line numbers of two lines. We need this to sort the lines; in fact we could do this using a comparison predicate. However, this way, it is easier, albeit unintuitive since two lines really have no god-given order relation.

operator==()

template<typename number = double>

bool AffineConstraints< number >::ConstraintLine::operator==

(

const ConstraintLine &

)

const

This operator is likewise weird: it checks whether the line indices of the two operands are equal, irrespective of the fact that the contents of the line may be different.

memory_consumption()

template<typename number = double>

std::size_t AffineConstraints< number >::ConstraintLine::memory_consumption

(

)

const

Determine an estimate for the memory consumption (in bytes) of this object.

serialize()

template<typename number = double>

template<class Archive >

void AffineConstraints< number >::ConstraintLine::serialize ( Archive &  ar, const unsigned int    )

inline

Support for boost:serialization.

Member Data Documentation

index

template<typename number = double>

size_type AffineConstraints< number >::ConstraintLine::index

Global DoF index of this line. Since only very few lines are stored, we can not assume a specific order and have to store the index explicitly.

Definition at line 1223 of file affine_constraints.h.

entries

template<typename number = double>

Entries AffineConstraints< number >::ConstraintLine::entries

Row numbers and values of the entries in this line.

For the reason why we use a vector instead of a map and the consequences thereof, the same applies as what is said for AffineConstraints::lines.

Definition at line 1232 of file affine_constraints.h.

inhomogeneity

template<typename number = double>

number AffineConstraints< number >::ConstraintLine::inhomogeneity

Value of the inhomogeneity.
