Detailed Description

template<class SMR>
class SmrNode< SMR >

Node in a simplicial mesh that stores iterators to all incident cells.

Parameters:

Mesh

is the simplicial mesh.

The base class has the vertex, an iterator to itself, and an identifier. This class stores iterators to all incident cells.

Member Function Documentation

template<class SMR >

int SmrNode< SMR >::getIdentifier

(

)

const [inline]

Return the identifier of this node.

Typically, the identifier is in the range [0...num_vertices). and a value of -1 indicates that the identifier has not been calculated.

Referenced by SmrNode< SMR >::put().

template<class SMR >

bool SmrNode< SMR >::isOnBoundary

(

)

const [inline]

Return true if the node is on the boundary.

The node is on the boundary if there are any incident boundary faces. To determine this, we examine each of the incident cells.

References SmrNode< SMR >::getSelf().

template<class SMR >

void SmrNode< SMR >::replace

(

NodeIterator

node

)

[inline]

Replace this node with the specified one.

This amounts to changing the simplex-vertex incidences.

template<class SMR >

void SmrNode< SMR >::setIdentifier

(

const int

identifier

)

const [inline]

Set the identifier.

Note:

This member function is const because the identifier is mutable. It is intended to be modified as the mesh changes.
