ITK: itk::fem::Load Class Reference

Duplicates the currect object. This function must be implemented by every derived class to create an exact copy of an object. The function returns a pointer to a base class.

Implemented in itk::fem::FiniteDifferenceFunctionLoad< TMoving, TFixed >, itk::fem::Element2DC1Beam, itk::fem::Element::Node, itk::fem::ImageMetricLoad< TMoving, TFixed >, itk::fem::LoadBC, itk::fem::LoadBCMFC, itk::fem::LoadEdge, itk::fem::LoadElement, itk::fem::LoadGravConst, itk::fem::LoadLandmark, itk::fem::LoadNode, itk::fem::LoadPoint, itk::fem::LoadTest< TClass >, and itk::fem::MaterialLinearElasticity.

static FEMLightObject::Pointer itk::fem::FEMLightObject::CreateFromStream	(	std::istream &	f,
		void *	info
	)			`[static, inherited]`

Read object of any derived type from stream.

This static function creates an object of a class, which is derived from FEMLightObject. The class of object is first determined from the stream, then the object of that class is constructed using the FEMObjectFactory. Finally the data for this object is read from the stream, by calling the Read() member function.

virtual Solution::ConstPointer itk::fem::Load::GetSolution ( ) [inline, virtual]

Reimplemented in itk::fem::FiniteDifferenceFunctionLoad< TMoving, TFixed >, itk::fem::ImageMetricLoad< TMoving, TFixed >, and itk::fem::LoadLandmark.

virtual void itk::fem::FEMLightObject::Read	(	std::istream &	f,
		void *	info
	)			`[virtual, inherited]`

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.

virtual void itk::fem::Load::SetSolution ( Solution::ConstPointer ) [inline, virtual]

Sets the pointer to solution vector. This function is automatically called by the Solver class on every load object.

Some types of external Loads may need access to previous values of solution vector. If a derived class needs that, it should implement this function, and store the passed pointer accordingly. If the result vector is not required, the functionn should be left unimplemented, so that only the dummy implementation in base class is called.

Parameters:

ptr

Pointer to the object of Solution class.

static void itk::fem::FEMLightObject::SkipWhiteSpace ( std::istream & f ) [static, inherited]

Helper function that skips all the whitespace and comments in an input stream.

virtual void itk::fem::FEMLightObject::Write ( std::ostream & f ) const [virtual, inherited]

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.

int itk::fem::FEMLightObject::GN [inherited]

Global number of an object (ID of an object) In general the ID's are required to be unique only within a specific type of derived classes (Elements, Nodes, ...) If the GN is not required, it can be ignored. (normally you need the GN when writing or reading objects to/from stream.

const std::string itk::fem::FEMLightObject::whitespaces [static, inherited]

Const string of all whitespace characters. This string is used by SkipWhiteSpace function.
