Member Function Documentation

static vtkPoints* vtkPoints::New ( int  dataType  )  [static]

static vtkPoints* vtkPoints::New (  )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

Reimplemented in vtkPointsProjectedHull.

virtual const char* vtkPoints::GetClassName (  )  [virtual]

Reimplemented from vtkObject.

static int vtkPoints::IsTypeOf ( const char *  name  )  [static]

Return 1 if this class type 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.

virtual int vtkPoints::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.

static vtkPoints* vtkPoints::SafeDownCast ( vtkObject o  )  [static]

Reimplemented from vtkObject.

void vtkPoints::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 vtkPointsProjectedHull.

virtual int vtkPoints::Allocate ( const vtkIdType  sz,
const vtkIdType  ext = 1000 
) [virtual]

Allocate initial memory size.

virtual void vtkPoints::Initialize (  )  [virtual]

Return object to instantiated state.

Reimplemented in vtkPointsProjectedHull.

virtual void vtkPoints::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.)

vtkDataArray* vtkPoints::GetData (  )  [inline]

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.)

Definition at line 94 of file vtkPoints.h.

virtual void vtkPoints::DeepCopy ( vtkPoints ad  )  [virtual]

virtual void vtkPoints::ShallowCopy ( vtkPoints ad  )  [virtual]

Different ways to copy data. Shallow copy does reference count (i.e., assigns pointers and updates reference count); deep copy runs through entire data array assigning values.

unsigned long vtkPoints::GetActualMemorySize (  ) 

Return the memory in kilobytes consumed by this attribute data. Used to support streaming and reading/writing data.
