Detailed Description

iterator used to traverse cells

This class (and subclasses) are used to iterate over cells. Use it only in conjunction with vtkGenericDataSet (i.e., the adaptor framework).

Typical use is:

vtkGenericDataSet *dataset;
vtkGenericCellIterator *it = dataset->NewCellIterator(2);
for (it->Begin(); !it->IsAtEnd(); it->Next());
  {
  spec=it->GetCell();
  }

◆ IsA()

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 vtkObjectBase.

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.

◆ Begin()

virtual void vtkGenericCellIterator::Begin ( )
pure virtual

Move iterator to first position if any (loop initialization).

◆ IsAtEnd()

virtual vtkTypeBool vtkGenericCellIterator::IsAtEnd ( )
pure virtual

Is the iterator at the end of traversal?

◆ NewCell()

virtual vtkGenericAdaptorCell* vtkGenericCellIterator::NewCell ( )
pure virtual

Create an empty cell.

The user is responsible for deleting it.

Postcondition
result_exists: result!=0

◆ GetCell() [1/2]

virtual void vtkGenericCellIterator::GetCell ( vtkGenericAdaptorCell c)
pure virtual

Get the cell at current position.

The cell should be instantiated with the NewCell() method.

Precondition
not_at_end: !IsAtEnd()
c_exists: c!=0 THREAD SAFE

◆ GetCell() [2/2]

virtual vtkGenericAdaptorCell* vtkGenericCellIterator::GetCell ( )
pure virtual

Get the cell at the current traversal position.

NOT THREAD SAFE

Precondition
not_at_end: !IsAtEnd()
Postcondition
result_exits: result!=0

◆ Next()

virtual void vtkGenericCellIterator::Next ( )
pure virtual

Move the iterator to the next position in the list.

Precondition
not_at_end: !IsAtEnd()
