Detailed Description

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.

vtkDataSet vtkFieldData vtkDataObjectSource vtkDataObjectFilter vtkDataObjectMapper vtkDataObjectToDataSet vtkFieldDataToAttributeDataFilter
Examples:
vtkDataObject (Examples)
Tests:
vtkDataObject (Tests)
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.

virtual void vtkDataObject::Update (  )  [virtual]

Provides opportunity for the data object to insure internal consistency before access. Also causes owning source/filter (if any) to update itself. The Update() method is composed of UpdateInformation(), PropagateUpdateExtent(), TriggerAsynchronousUpdate(), and UpdateData().

virtual void vtkDataObject::UpdateInformation (  )  [virtual]

WARNING: INTERNAL METHOD - NOT FOR GENERAL USE. THIS METHOD IS PART OF THE PIPELINE UPDATE FUNCTIONALITY. Update all the "easy to update" information about the object such as the extent which will be used to control the update. This propagates all the way up then back down the pipeline. As a by-product the PipelineMTime is updated.

Reimplemented in vtkImageData.

virtual void vtkDataObject::PropagateUpdateExtent (  )  [virtual]

WARNING: INTERNAL METHOD - NOT FOR GENERAL USE. THIS METHOD IS PART OF THE PIPELINE UPDATE FUNCTIONALITY. The update extent for this object is propagated up the pipeline. This propagation may early terminate based on the PipelineMTime.

virtual void vtkDataObject::TriggerAsynchronousUpdate (  )  [virtual]

WARNING: INTERNAL METHOD - NOT FOR GENERAL USE. THIS METHOD IS PART OF THE PIPELINE UPDATE FUNCTIONALITY. Propagate back up the pipeline for ports and trigger the update on the other side of the port to allow for asynchronous parallel processing in the pipeline. This propagation may early terminate based on the PipelineMTime.

virtual void vtkDataObject::UpdateData (  )  [virtual]

WARNING: INTERNAL METHOD - NOT FOR GENERAL USE. THIS METHOD IS PART OF THE PIPELINE UPDATE FUNCTIONALITY. Propagate the update back up the pipeline, and perform the actual work of updating on the way down. When the propagate arrives at a port, block and wait for the asynchronous update to finish on the other side. This propagation may early terminate based on the PipelineMTime.

virtual unsigned long vtkDataObject::GetEstimatedMemorySize (  )  [virtual]

Get the estimated size of this data object itself. Should be called after UpdateInformation() and PropagateUpdateExtent() have both been called. Should be overridden in a subclass - otherwise the default is to assume that this data object requires no memory. The size is returned in kilobytes.

Reimplemented in vtkImageData.

virtual void vtkDataObject::SetUpdateExtent ( int  piece,
int  numPieces,
int  ghostLevel 
) [virtual]

A generic way of specifying an update extent. Subclasses must decide what a piece is. When the NumberOfPieces is zero, then no data is requested, and the source will not execute.

void vtkDataObject::SetUpdateExtent ( int  piece,
int  numPieces 
) [inline]

A generic way of specifying an update extent. Subclasses must decide what a piece is. When the NumberOfPieces is zero, then no data is requested, and the source will not execute.

) [virtual]

Set the update extent for data objects that use 3D extents. Using this method on data objects that set extents as pieces (such as vtkPolyData or vtkUnstructuredGrid) has no real effect. Don't use the set macro to set the update extent since we don't want this object to be modified just due to a change in update extent. When the volume of the extent is zero (0, -1,..), then no data is requested, and the source will not execute.

virtual void vtkDataObject::SetUpdateExtent ( int  extent[6]  )  [virtual]

Set the update extent for data objects that use 3D extents. Using this method on data objects that set extents as pieces (such as vtkPolyData or vtkUnstructuredGrid) has no real effect. Don't use the set macro to set the update extent since we don't want this object to be modified just due to a change in update extent. When the volume of the extent is zero (0, -1,..), then no data is requested, and the source will not execute.

virtual int* vtkDataObject::GetUpdateExtent (  )  [virtual]

Set the update extent for data objects that use 3D extents. Using this method on data objects that set extents as pieces (such as vtkPolyData or vtkUnstructuredGrid) has no real effect. Don't use the set macro to set the update extent since we don't want this object to be modified just due to a change in update extent. When the volume of the extent is zero (0, -1,..), then no data is requested, and the source will not execute.

Definition at line 217 of file vtkDataObject.h.

unsigned long vtkDataObject::GetUpdateTime (  ) 

Used by Threaded ports to determine if they should initiate an asynchronous update (still in development).

void vtkDataObject::SetUpdateExtentToWholeExtent (  ) 

If the whole input extent is required to generate the requested output extent, this method can be called to set the input update extent to the whole input extent. This method assumes that the whole extent is known (that UpdateInformation has been called)

unsigned long vtkDataObject::GetPipelineMTime (  ) 

Get the cumulative modified time of everything upstream. Does not include the MTime of this object.

virtual unsigned long vtkDataObject::GetActualMemorySize (  )  [virtual]

Return the actual size of the data in kilobytes. This number is valid only after the pipeline has updated. The memory size returned is guaranteed to be greater than or equal to the memory required to represent the data (e.g., extra space in arrays, etc. are not included in the return value).

make the output data ready for new data to be inserted. For most objects we just call Initialize. But for vtkImageData we leave the old data in case the memory can be reused.

Reimplemented in vtkImageData.

void vtkDataObject::SetExtentTranslator ( vtkExtentTranslator translator  ) 

An object that will translate pieces into structured extents.

vtkExtentTranslator* vtkDataObject::GetExtentTranslator (  ) 

An object that will translate pieces into structured extents.

virtual int vtkDataObject::GetExtentType (  )  [inline, virtual]

The ExtentType will be left as VTK_PIECES_EXTENT for data objects such as vtkPolyData and vtkUnstructuredGrid. The ExtentType will be changed to VTK_3D_EXTENT for data objects with 3D structure such as vtkImageData (and its subclass vtkStructuredPoints), vtkRectilinearGrid, and vtkStructuredGrid. The default is the have an extent in pieces, with only one piece (no streaming possible).

Reimplemented in vtkImageData, vtkRectilinearGrid, vtkStructuredGrid, vtkTemporalDataSet, and vtkImageStencilData.

virtual void vtkDataObject::Crop (  )  [virtual]

This method crops the data object (if necesary) so that the extent matches the update extent.

Reimplemented in vtkImageData, vtkPolyData, vtkRectilinearGrid, and vtkStructuredGrid.

static const char* vtkDataObject::GetAssociationTypeAsString ( int  associationType  )  [static]

Given an integer association type, this static method returns a string type for the attribute (i.e. type = 0: returns "Points").
