Member Function Documentation

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

vtkPoints* vtkPoints::New (    )  [static]
 

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

Reimplemented from vtkObject.

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

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

int vtkPoints::IsTypeOf (  const char *    type )  [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 *    type )  [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.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

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.

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.

vtkPoints* vtkPoints::MakeObject (    ) 
 

Creates object of same type as this object.

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.)
