This class represents one constraint in an AffineConstraints object.
Definition at line 1571 of file affine_constraints.h.
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.
Definition at line 1577 of file affine_constraints.h.
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 godgiven order relation.
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.
std::size_t AffineConstraints< number >::ConstraintLine::memory_consumption  (  )  const 
Determine an estimate for the memory consumption (in bytes) of this object.

inline 
Write and read the data of this object from a stream for the purpose of serialization using the BOOST serialization library.
Definition at line 1632 of file affine_constraints.h.
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 1584 of file affine_constraints.h.
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 1593 of file affine_constraints.h.
number AffineConstraints< number >::ConstraintLine::inhomogeneity 
Value of the inhomogeneity.
