Detailed Description

Pipeline data object that contains multiple vtkArray objects.

Because vtkArray cannot be stored as attributes of data objects (yet), a "carrier" object is needed to pass vtkArray through the pipeline. vtkArrayData acts as a container of zero-to-many vtkArray instances, which can be retrieved via a zero-based index. Note that a collection of arrays stored in vtkArrayData may-or-may-not have related types, dimensions, or extents.
