Detailed Description

Class that stores information required to define a node.

A node can define a point in space and can hold an arbitrary number of coordinates and the DOFs. Since the only classes that use nodes are the elements, the node class is defined within an element base class.

Self::Pointer itk::fem::Node::New void    [inline, static]
 

Object creation in an itk compatible way

Definition at line 139 of file itkFEMElementBase.h.

virtual void itk::fem::Node::Read std::istream &    f,
void *    info
[virtual]
 

Read an object data from input stream. Call this member to initialize the data members in the current object by reading data from provided input stream. Derived classes should first call the the parent's read function, to initialize the data from parent. Note that you must manually create the object of desired type using the FEMObjectFactory before you can call read function (this is pretty obvious). In this class only the global number is read from file. Derived classes may require some additional info in order to perform the reading. Pack this info in an object and pass a pointer to it in the info parameter. If you need runtime typechecking, use a polymorphic class and dynamic_cast operator inside the implementation of Read.

Reimplemented from itk::fem::FEMLightObject.

void itk::fem::Node::SetCoordinates const VectorType   coords [inline]
 

Set coordinates of a node.

Definition at line 188 of file itkFEMElementBase.h.

void itk::fem::Node::SetDegreeOfFreedom unsigned int    i,
DegreeOfFreedomIDType    dof
const [inline]
 

Set DOF IDs associated with this node.

Definition at line 204 of file itkFEMElementBase.h.

virtual void itk::fem::Node::Write std::ostream &    f const [virtual]
 

Write an object to the output stream. Call this member to write the data members in the current object to the output stream. Here we also need to know which derived class we actually are, so that we can write the class name. The class name is obtained by calling the virtual ClassID() member function and passing the result to the FEMObjectFactory.

Implementations of Write member funtion in derived classes should first call the parent's implementation of Write and finaly write whatever they need.

Reimplemented from itk::fem::FEMLightObject.
