A class that represents an access to a face in 1d – i.e. to a point. This is not a full fledged access from which you can build an iterator: for example, you can't iterate from one such point to the next. Point also don't have children, and they don't have neighbors.

typedef void TriaAccessor< 0, 1, spacedim >::AccessorData |
Pointer to internal data.
Definition at line 1744 of file tria_accessor.h.
enum TriaAccessor< 0, 1, spacedim >::VertexKind |
Whether the vertex represented here is at the left end of the domain, the right end, or in the interior.
Definition at line 1752 of file tria_accessor.h.

Constructor.
Since there is no mapping from vertices to cells, an accessor object for a point has no way to figure out whether it is at the boundary of the domain or not. Consequently, the second argument must be passed by the object that generates this accessor – e.g. a 1d cell that can figure out whether its left or right vertex are at the boundary.
The third argument is the global index of the vertex we point to.

Constructor. This constructor exists in order to maintain interface compatibility with the other accessor classes. However, it doesn't do anything useful here and so may not actually be called.
Definition at line 2066 of file tria_accessor.templates.h.

inline |
Constructor. Should never be called and thus produces an error.

Copy operator. Since this is only called from iterators, do not return anything, since the iterator will return itself.
This method is protected, since it is only to be called from the iterator class.
Definition at line 2119 of file tria_accessor.templates.h.
|
inlinestatic |
Return the state of the iterator. Since an iterator to points can not be incremented or decremented, its state remains constant, and in particular equal to IteratorState::valid.
Definition at line 2131 of file tria_accessor.templates.h.
|
inlinestatic |
Level of this object. Vertices have no level, so this function always returns zero.
Definition at line 2140 of file tria_accessor.templates.h.
|
inline |
Index of this object. Returns the global index of the vertex this object points to.
Definition at line 2150 of file tria_accessor.templates.h.
|
inline |
This operator advances the iterator to the next element. For points, this operation is not defined, so you can't iterate over point iterators.
Definition at line 2160 of file tria_accessor.templates.h.

inline |
This operator moves the iterator to the previous element. For points, this operation is not defined, so you can't iterate over point iterators.

inlinestatic |
Index of the parent. You can't do this for points.
Definition at line 2209 of file tria_accessor.templates.h.
|
inline |
Return the global index of i-th vertex of the current object. If i is zero, this returns the index of the current point to which this object refers. Otherwise, it throws an exception.
Note that the returned value is only the index of the geometrical vertex. It has nothing to do with possible degrees of freedom associated with it. For this, see the DoFAccessor::vertex_dof_index
functions.
Definition at line 2218 of file tria_accessor.templates.h.
|
inline |
Return a reference to the ith
vertex. If i is zero, this returns a reference to the current point to which this object refers. Otherwise, it throws an exception.
Definition at line 2230 of file tria_accessor.templates.h.
|
inline |
Return the center of this object, which of course co-incides with the location of the vertex this object refers to.
Definition at line 2242 of file tria_accessor.templates.h.
|
inlinestatic |
Pointer to the ith
line bounding this object. Will point to an invalid object.
Definition at line 2252 of file tria_accessor.templates.h.

inlinestatic |
Line index of the ith
line bounding this object.
Implemented only for structdim>1
, otherwise an exception generated.

inlinestatic |
Pointer to the ith
quad bounding this object.
Definition at line 2271 of file tria_accessor.templates.h.
|
inlinestatic |
Quad index of the ith
quad bounding this object.
Implemented only for structdim>2
, otherwise an exception generated.
Definition at line 2281 of file tria_accessor.templates.h.

inline |
Return whether this point is at the boundary of the one-dimensional triangulation we deal with here.
Definition at line 2291 of file tria_accessor.templates.h.
|
inline |
Boundary indicator of this object. The convention for one dimensional triangulations is that left end vertices have boundary indicator zero, and right end vertices have boundary indicator one.
If the return value is the special value numbers::internal_face_boundary_id, then this object is in the interior of the domain.
Definition at line 2300 of file tria_accessor.templates.h.

inlinestatic |
Test whether the object has children. Always false.
Definition at line 2359 of file tria_accessor.templates.h.
|
inlinestatic |
Return the number of immediate children of this object.This is always zero in dimension 0.
Definition at line 2368 of file tria_accessor.templates.h.
|
inlinestatic |
Compute and return the number of active descendants of this objects. Always zero.
Definition at line 2377 of file tria_accessor.templates.h.
|
inlinestatic |
Return the number of times that this object is refined. Always 0.
Definition at line 2386 of file tria_accessor.templates.h.

inlinestatic |
Always return no refinement.
Definition at line 2412 of file tria_accessor.templates.h.

Return whether the vertex pointed to here is used.

Dimension of the space the object represented by this accessor lives in. For example, if this accessor represents a quad that is part of a two-dimensional surface in four-dimensional space, then this value is four.
Definition at line 1716 of file tria_accessor.h.
|
static |
Dimensionality of the object that the thing represented by this accessopr is part of. For example, if this accessor represents a line that is part of a hexahedron, then this value will be three.
Definition at line 1727 of file tria_accessor.h.
|
static |
Dimensionality of the current object represented by this accessor. For example, if it is line (irrespective of whether it is part of a quad or hex, and what dimension we are in), then this value equals 1.
Definition at line 1739 of file tria_accessor.h.

protected |
Pointer to the triangulation we operate on.
Definition at line 2183 of file tria_accessor.h.

Whether this is a left end, right end, or interior vertex. This information is provided by the cell at the time of creation.

The global vertex index of the vertex this object corresponds to.
