Array class that holds special pointers to the load objects
Definition at line 45 of file itkFEMLoadBase.h.

typedef Self itk::fem::FEMLightObject::Baseclass [inherited]

Store the base class typedef for easy access from derived classes. FEM_CLASS macro also expects this for the FEMOF...
Definition at line 67 of file itkFEMLightObject.h.

typedef const Self* itk::fem::LoadBC::ConstPointer

Const pointer or SmartPointer to an object.
Reimplemented from itk::fem::Load.
Definition at line 36 of file itkFEMLoadBC.h.

typedef Self* itk::fem::LoadBC::Pointer

Pointer or SmartPointer to an object.
Reimplemented from itk::fem::Load.
Definition at line 36 of file itkFEMLoadBC.h.

Constructor & Destructor Documentation

itk::fem::LoadBC::LoadBC ( ) [inline]

Default constructor
Definition at line 61 of file itkFEMLoadBC.h.

Member Function Documentation

virtual int itk::fem::LoadBC::ClassID ( ) const [inline, virtual]

Virtual function to access the class ID
Implements itk::fem::FEMLightObject.
Definition at line 36 of file itkFEMLoadBC.h.

virtual Baseclass::Pointer itk::fem::LoadBC::Clone ( ) const [virtual]

Create a new object from the existing one
Implements itk::fem::FEMLightObject.

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, inherited]

Reimplemented in itk::fem::FiniteDifferenceFunctionLoad< TMoving, TFixed >, itk::fem::ImageMetricLoad< TMoving, TFixed >, itk::fem::LoadLandmark, and itk::fem::FiniteDifferenceFunctionLoad< MovingImageType, FixedImageType >.
Definition at line 60 of file itkFEMLoadBase.h.

static Self::Pointer itk::fem::LoadBC::New ( void ) [inline, static]

Object creation in an itk compatible way
Definition at line 36 of file itkFEMLoadBC.h.

virtual void itk::fem::LoadBC::Read ( std::istream & f,

void * info

) [virtual]

Read a LoadBC object from input stream.
Reimplemented from itk::fem::FEMLightObject.

Reimplemented in itk::fem::FiniteDifferenceFunctionLoad< TMoving, TFixed >, itk::fem::ImageMetricLoad< TMoving, TFixed >, itk::fem::LoadLandmark, and itk::fem::FiniteDifferenceFunctionLoad< MovingImageType, FixedImageType >.
Definition at line 59 of file itkFEMLoadBase.h.

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::LoadBC::Write ( std::ostream & f ) const [virtual]

Write a LoadBC object to the output stream
Reimplemented from itk::fem::FEMLightObject.

Member Data Documentation

const int itk::fem::LoadBC::CLID [static]

Class ID for FEM object factory
Definition at line 36 of file itkFEMLoadBC.h.

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.
Definition at line 168 of file itkFEMLightObject.h.
Referenced by itk::fem::FEMLightObject::FEMLightObject().

unsigned int itk::fem::LoadBC::m_dof

Local DOF number within the Element object.
Definition at line 48 of file itkFEMLoadBC.h.

Element::ConstPointer itk::fem::LoadBC::m_element

Pointer to an element, which holds the DOF that is affected by boundary condition.
Definition at line 43 of file itkFEMLoadBC.h.

vnl_vector<Element::Float> itk::fem::LoadBC::m_value

Value which the DOF is being fixed.

Note:
This is a vector so that implementation of BC on isotropic elements is easy. Which value is applied to the master force vector is defined by optional dim parameter (defaults to 0) in AssembleF function in solver.

Definition at line 58 of file itkFEMLoadBC.h.

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

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