general representation of visualization data
helper class to get VTK data object types as string and instantiate them
vtkDataObject is an general representation of visualization data. It serves to encapsulate instance variables and methods for visualization network execution, as well as representing data consisting of a field (i.e., just an unstructured pile of data). This is to be compared with a vtkDataSet, which is data with geometric and/or topological structure.
vtkDataObjects are used to represent arbitrary repositories of data via the vtkFieldData instance variable. These data must be eventually mapped into a concrete subclass of vtkDataSet before they can actually be displayed.
vtkDataObjectTypes is a helper class that supports conversion between integer types defined in vtkType.h and string names as well as creation of data objects from either integer or string types. This class has to be updated every time a new data type is added to VTK.

This method crops the data object (if necessary) so that the extent matches the update extent.
Reimplemented in vtkExplicitStructuredGrid, vtkImageData, vtkRectilinearGrid, and vtkStructuredGrid.
|
virtual |
Returns the attributes of the data object of the specified attribute type.
The type may be:
The other attribute type, FIELD, will return nullptr since field data is stored as a vtkFieldData instance, not a vtkDataSetAttributes instance. To retrieve field data, use GetAttributesAsFieldData.
Reimplemented in vtkCellGrid, and vtkGenericDataSet.
|
virtual |
Returns the ghost arrays of the data object of the specified attribute type.
The type may be:
The other attribute types, will return nullptr since ghosts arrays are not defined for now outside of point or cell.
Reimplemented in vtkCellGrid, and vtkDataSet.
|
virtual |
Returns if this type of data object support ghost array for specified type.
The type may be:
The other attribute types, will return false since ghosts arrays are not defined for now outside of point or cell. for vtkDataObject, this always return false but subclasses may override this method and implement their own logic.
Reimplemented in vtkCellGrid, vtkCompositeDataSet, vtkDataSet, and vtkHyperTreeGrid.
|
virtual |
Returns the attributes of the data object as a vtkFieldData.
This returns non-null values in all the same cases as GetAttributes, in addition to the case of FIELD, which will return the field data for any vtkDataObject subclass.
Reimplemented in vtkDataSet, vtkGraph, vtkHyperTreeGrid, and vtkTable.
|
virtual |
Retrieves the attribute type that an array came from.
This is useful for obtaining which attribute type a input array to an algorithm came from (retrieved from GetInputAbstractArrayToProcesss).
Reimplemented in vtkCellGrid.
|
virtual |
Get the number of elements for a specific attribute type (POINT, CELL, etc.).
Reimplemented in vtkCellGrid, vtkCompositeDataSet, vtkDataSet, vtkGenericDataSet, vtkGraph, vtkHyperTreeGrid, and vtkTable.
|
static |
Given an integer association type, this static method returns a string type for the attribute (i.e.
associationType = 0: returns "Points").
|
static |
Given a string association name, this static method returns an integer association type for the attribute (i.e.
associationName = "Points": returns 0).
|

Retrieve an instance of this class from an information object.
