Detailed Description

create an instance of any VTK class from its name.

vtkInstantiator provides an interface to create an instance of any VTK class from its name. Instances are created through registered pointers to functions returning the objects. New classes can also be registered with the creator. VTK libraries automatically register their classes with the creator when they are loaded. Instances are created using the static New() method, so the normal vtkObjectFactory mechanism is still invoked.

When using this class from language wrappers (Tcl, Python, or Java), the vtkInstantiator should be able to create any class from any kit that has been loaded.

In C++ code, one should include the header for each kit from which one wishes to create instances through vtkInstantiator. This is necessary to ensure proper linking when building static libraries. Be careful, though, because including each kit's header means every class from that kit will be linked into your executable whether or not the class is used. The headers are:

vtkCommon - vtkCommonInstantiator.h vtkFiltering - vtkFilteringInstantiator.h vtkIO - vtkIOInstantiator.h vtkImaging - vtkImagingInstantiator.h vtkGraphics - vtkGraphicsInstantiator.h vtkRendering - vtkRenderingInstantiator.h vtkVolumeRendering - vtkVolumeRenderingInstantiator.h vtkHybrid - vtkHybridInstantiator.h vtkParallel - vtkParallelInstantiator.h

The VTK_MAKE_INSTANTIATOR() command in CMake is used to automatically generate the creator registration for each VTK library. It can also be used to create registration code for VTK-style user libraries that are linked to vtkCommon. After using this command to register classes from a new library, the generated header must be included.

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObjectBase.

static vtkObject* vtkInstantiator::CreateInstance ( const char *  className)
static

Create an instance of the class whose name is given.

If creation fails, a nullptr pointer is returned.

static void vtkInstantiator::RegisterInstantiator ( const char *  className,
CreateFunction  createFunction 
)
static

Register a function to create instances of the class whose name is given.

This allows more than one create function to be registered for the same class. The first one registered is used until it is unregistered.

static void vtkInstantiator::UnRegisterInstantiator ( const char *  className,
CreateFunction  createFunction 
)
static

Unregister the instance creation of the class whose name is given.

This will unregister the function given, but any other function registered for the same class will be left untouched.
