From 23f10a989aca2146ba1f2782fa92fdca4fd7d280 Mon Sep 17 00:00:00 2001 From: Kent Williams Date: Wed, 29 Jun 2011 13:34:19 -0500 Subject: [PATCH] ENH: FEM refactoring as contracted for ITKv4 This commit makes the FEM framework more ITK like. There is now a FEMObject to define the finite element problem and the Solver derives from ProcessObject. Substantially more testing is performed on this code. Much of this work was contributed by Kiran Shivanna. UPD: All tests now pass except itkFEMC0TriangularElement-Quadratic. This result needs to be revied for numerical differences between Solvers UPD: Currently disable FEM registration test. This needs to be refoctored UPD: Updated regression tests. Removed FEM Registration tests UPD: Replaced explicit New() with itkSimpleNewMacro() UPD: Added the itkFEMRegistrationFilter and updated tests UPD: Fixed a bug in the FEM Registration filter test UPD: Added landmarks to regiatration BUG: Added Landmark points back into loading ENH: Added test data to suite of FEM tools. Test data added to FEM toolkit for supporting new refactored framework. COMP: Fix circular dependency issue btw FEM and SpatialObjects COMP: Compile errors COMP: Commented out Examples to allow building. Worked with Brad King to fix bugs in the DATA{} upload mechanism ENH: Decoupled reading of FEM objects. BUG: Fixed failing tests and documentation STYLE: Removed unnecessary files from build tree. COMP: Rebased to current ITK, to pick up new MetaIO for FEM COMP: cppcheck static analysis FEM specific code from SpatialObjects was extracted to the FEM module, and a generic registration interface was added to Spatial Object to allow runtime additions of supported objects that conform to the SpatialObject interface.

-}; - -/** - * \class VisitorDispatcher - * \brief This class provides the functionality needed to apply the correct - * visitor function to object of some class. The specific visitor - * function is choosen, based on a given pointer to some object. - * - * A visitor function is a function, that can perform various operations on - * objects of various classes. Usually we want this operation applied on - * any of the polymorphic derived classes. The specific operation is - * defined in visitor functions. - * - * For example: calculating the area of Shape objects. In this case the - * function that calculates the area of a specific shape, is called the - * visitor function. A specific version of this function must be defined - * for each class, on which you want the perform the operation (Area(Circle*); - * Area(Square*); ...). - * - * Now suppose that you want different operations performed on the shape - * objects. Which operation will be performed is specified by the class of - * the Visitor object. If the Visitor object is of class Area, then the - * area of objects will be calculated. If the visitor is object of class - * Circumference, then the circumference of the shapes will be calculated... - * - * In order to be able to do that and provide the framework to easily add - * new Visitor as well as Visited classes, we create the VisitorDispatcher - * class. It is implemented as a singelton. It stores pointers to Visitor - * functions together with the information about which Visitor function must - * be called in order to perform an operation specified by Visitor class on - * objects of Visited class. - * - * To make a specific base class and all its derived classes visitable, you - * must make the following changes to your code: - * - * 1. Declare the folowing virtual member function in the base class: - * - * class BaseVisitable - * { - * ... - * virtual ReturnType AcceptVisitor( VisitorBase* ) = 0; - * ... - * }; - * - * 2. Implement this function in ALL derived classes like this: - * - * class MyVisitableClass : public BaseVisitable - * { - * ... - * virtual ReturnType AcceptVisitor( VisitorBase* l ) - * { - * return VisitorDispatcher::Visit( ); - * } - * ... - * }; - * - * Since this code is the same for all derived element classes, you should - * probably put it in the macro. - * - * 3. Register each visitor class with the VisitorDispatcher class before it - * is called. This is done by calling the member function RegisterVisitor - * of the VisitorDispatcher class and providing the pointer to the Visitor - * function that performs the required task. The visitor function must be - * declared according to the VisitFunctionPointerType template parameter. - * - * ReturnType MyVisitor_Function( ... ); - * - * - * Once all this is done, you can perform various operations on objects of - * all derived classes by simply calling the Visit function on the pointer - * to base class and providing a pointer to the specific Visitor object: - * - * object->AcceptVisitor(visitor); - * - * - * The Visitor class is templated over several classes that make its use - * generic and simple. - * - * - TVisitedClass Class of objects that will be visited. - * - * - TVisitorBase Base class of Visitor objects.
