Detailed Description
abstract superclass for arrays of numeric data
vtkDataArray is an abstract superclass for data array objects containing numeric data. It extends the API defined in vtkAbstractArray. vtkDataArray is an abstract superclass for data array objects. This class defines an API that all array objects must support. Note that the concrete subclasses of this class represent data in native form (char, int, etc.) and often have specialized more efficient methods for operating on this data (for example, getting pointers to data or getting/inserting data in native form). Subclasses of vtkDataArray are assumed to contain data whose components are meaningful when cast to and from double.
