overridevirtual

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.

◆ Allocate()

virtual vtkTypeBool vtkPoints2D::Allocate	(	vtkIdType	sz,
		vtkIdType	ext = `1000`
	)

virtual

Allocate initial memory size.

◆ Initialize()

virtual void vtkPoints2D::Initialize ( )

virtual

Return object to instantiated state.

◆ SetData()

virtual void vtkPoints2D::SetData ( vtkDataArray * )

virtual

Set/Get the underlying data array.

This function must be implemented in a concrete subclass to check for consistency. (The tuple size must match the type of data. For example, 3-tuple data array can be assigned to a vector, normal, or points object, but not a tensor object, which has a tuple dimension of 9. Scalars, on the other hand, can have tuple dimension from 1-4, depending on the type of scalar.)
