Detailed Description

Abstract superclass to iterate over elements in an vtkAbstractArray.

vtkArrayIterator is used to iterate over elements in any vtkAbstractArray subclass. The vtkArrayIteratorTemplateMacro is used to centralize the set of types supported by Execute methods. It also avoids duplication of long switch statement case lists.

Note that in this macro VTK_TT is defined to be the type of the iterator for the given type of array. One must include the vtkArrayIteratorIncludes.h header file to provide for extending of this macro by addition of new iterators.

Example usage:

vtkArrayIter* iter = array->NewIterator();
switch(array->GetDataType())
{
vtkArrayIteratorTemplateMacro(myFunc(static_cast<VTK_TT*>(iter), arg2));
}
iter->Delete();

Constructor & Destructor Documentation

vtkArrayIterator::vtkArrayIterator ( )
protected

Get the data type from the underlying array. Returns 0 if no underlying array is present.

vtkArrayIterator::~vtkArrayIterator ( )
protected

Get the data type from the underlying array. Returns 0 if no underlying array is present.

Member Function Documentation

virtual const char* vtkArrayIterator::GetClassName ( )
virtual

Reimplemented from vtkObject.

Reimplemented in vtkBitArrayIterator.

static int vtkArrayIterator::IsTypeOf ( const char *  type)
static
virtual int vtkArrayIterator::IsA ( const char *  name)
virtual

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.

Reimplemented from vtkObject.

Reimplemented in vtkBitArrayIterator.

static vtkArrayIterator* vtkArrayIterator::SafeDownCast ( vtkObject o)
static
void vtkArrayIterator::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
virtual

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 vtkObject.

Reimplemented in vtkArrayIteratorTemplate< T >, and vtkBitArrayIterator.

virtual void vtkArrayIterator::Initialize ( vtkAbstractArray array)
pure virtual

Set the array this iterator will iterate over. After Initialize() has been called, the iterator is valid so long as the Array has not been modified (except using the iterator itself). If the array is modified, the iterator must be re-intialized.

Implemented in vtkArrayIteratorTemplate< T >, and vtkBitArrayIterator.

virtual int vtkArrayIterator::GetDataType ( )
pure virtual

Get the data type from the underlying array. Returns 0 if no underlying array is present.

Implemented in vtkArrayIteratorTemplate< T >, and vtkBitArrayIterator.
