Detailed Description

iterator used to traverse points

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

Typical use is:

vtkGenericDataSet *dataset;
vtkGenericPointIterator *it = dataset->NewPointIterator();
for (it->Begin(); !it->IsAtEnd(); it->Next());
  {
  x=it->GetPosition();
  }

Member Function Documentation

◆ IsTypeOf()

static int vtkGenericPointIterator::IsTypeOf ( const char * type )

static

◆ IsA()

virtual int vtkGenericPointIterator::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 vtkBridgePointIteratorOne, vtkBridgePointIteratorOnDataSet, vtkBridgePointIteratorOnCell, and vtkBridgePointIterator.

◆ SafeDownCast()

static vtkGenericPointIterator* vtkGenericPointIterator::SafeDownCast ( vtkObjectBase * o )

static

◆ NewInstanceInternal()

virtual vtkObjectBase* vtkGenericPointIterator::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkObject.

Reimplemented in vtkBridgePointIteratorOne, vtkBridgePointIteratorOnDataSet, vtkBridgePointIteratorOnCell, and vtkBridgePointIterator.

◆ NewInstance()

vtkGenericPointIterator* vtkGenericPointIterator::NewInstance ( ) const

◆ PrintSelf()

void vtkGenericPointIterator::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 vtkBridgePointIteratorOne, vtkBridgePointIteratorOnDataSet, vtkBridgePointIteratorOnCell, and vtkBridgePointIterator.

◆ Begin()

virtual void vtkGenericPointIterator::Begin ( )

pure virtual

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

Implemented in vtkBridgePointIteratorOne, vtkBridgePointIteratorOnDataSet, vtkBridgePointIteratorOnCell, and vtkBridgePointIterator.

◆ IsAtEnd()

virtual int vtkGenericPointIterator::IsAtEnd ( )

pure virtual

Is the iterator at the end of traversal?

Implemented in vtkBridgePointIteratorOne, vtkBridgePointIteratorOnDataSet, vtkBridgePointIteratorOnCell, and vtkBridgePointIterator.

◆ Next()

virtual void vtkGenericPointIterator::Next ( )

pure virtual

Move the iterator to the next position in the list.

Precondition: not_off: !IsAtEnd()

Implemented in vtkBridgePointIteratorOne, vtkBridgePointIteratorOnDataSet, vtkBridgePointIteratorOnCell, and vtkBridgePointIterator.

◆ GetPosition() [1/2]

virtual double* vtkGenericPointIterator::GetPosition ( )

pure virtual

Get the coordinates of the point at the current iterator position.

Precondition: not_off: !IsAtEnd()

Postcondition: result_exists: result!=0

Implemented in vtkBridgePointIteratorOne, vtkBridgePointIteratorOnDataSet, vtkBridgePointIteratorOnCell, and vtkBridgePointIterator.

◆ GetPosition() [2/2]

virtual void vtkGenericPointIterator::GetPosition ( double x[3] )

pure virtual

Get the coordinates of the point at the current iterator position.

Precondition: not_off: !IsAtEnd(); x_exists: x!=0

Implemented in vtkBridgePointIteratorOne, vtkBridgePointIteratorOnDataSet, vtkBridgePointIteratorOnCell, and vtkBridgePointIterator.

◆ GetId()

virtual vtkIdType vtkGenericPointIterator::GetId ( )

pure virtual

Return the unique identifier for the point, could be non-contiguous.

Precondition: not_off: !IsAtEnd()

Implemented in vtkBridgePointIteratorOne, vtkBridgePointIteratorOnDataSet, vtkBridgePointIteratorOnCell, and vtkBridgePointIterator.
