Detailed Description

Base class for all data objects in ITK.

This is the base class for all data objects in the Insight data processing pipeline. A data object is an object that represents and provides access to data. ProcessObjects (i.e., filters) operate on input data objects, producing new data objects as output. ProcessObject and DataObject are connected together into data flow pipelines.

void itk::DataObject::ComputeEstimatedPipelineMemorySize (  unsigned long    sizes[3] )

Methods used to estimate how much memory is used during a pipeline execution. These methods could be used to control the data streaming mechanism.

virtual void itk::DataObject::CopyInformation (  const DataObject *    )  [inline, virtual]

Copy information from the specified data set. This method is part of the pipeline execution model. By default, a ProcessObject will copy meta-data from the first input to all of its outputs. See ProcessObject::GenerateOutputInformation(). Each subclass of DataObject is responsible for being able to copy whatever meta-data it needs from from another DataObject. The default implementation of this method is empty. If a subclass overrides this method, it should always call its superclass' version.

Definition at line 309 of file itkDataObject.h. References HardConnectedComponentImageFilter::PrintSelf().

void itk::DataObject::DataHasBeenGenerated (    )

Inform the pipeline mechanism that data has been generated. This method is called by ProcessObject::UpdateOutputData() once the process object has finished generating its data. This essentially marks the DataObject as being updated and ready for use.

void itk::DataObject::DisconnectPipeline (    )  const

Separate this data object from the pipeline. This routine disconnects a data object from the upstream pipeline. Hence an Update() from downstream will not propagate back past this data object. To completely isolate this data object from the pipeline, the application must remove this data object from any filters which it is connected as the input.

virtual unsigned long itk::DataObject::GetActualMemorySize (    )  [virtual]

Methods used to estimate how much memory is used during a pipeline execution. These methods could be used to control the data streaming mechanism.

virtual const char* itk::DataObject::GetClassName (    )  const [virtual]

(Note: we cannot use the GetObjectMacro() defined in itkMacro because the mutual dependency of DataObject and ProcessObject causes compile problems. Also, a forward reference smart pointer is returned, not a smart pointer, because of the circular dependency between the process and data object.) GetSource() returns a SmartPointerForwardReference and not a WeakPointer because it is assumed the code calling GetSource() wants to hold a long term reference to the source.

unsigned int itk::DataObject::GetSourceOutputIndex (    )  const

Which of the source's outputs corresponds to this data object?

virtual void itk::DataObject::PrepareForNewData (    )  [inline, virtual]

Setup a DataObject to receive new data. This method is called by the pipeline mechanism on each output of filter that needs to execute. The default implementation is to return a DataObject to its initial state. This may involve releasing previously allocated bulk data. Subclasses of DataObject may want to override this method and/or the Initialize() method if they want a different default behavior (for instance a DataObject might want finer control over its bulk data memory management).

virtual void itk::DataObject::PropagateRequestedRegion (    )  throw (InvalidRequestedRegionError) [virtual]

Methods to update the pipeline.

virtual void itk::DataObject::PropagateResetPipeline (    )  [protected, virtual]

Propagate a call to ResetPipeline(). Called only from ProcessObject.

void itk::DataObject::ReleaseData (    )

Release data back to system to conserve memory resource. Used during pipeline execution. Releasing this data does not make down-stream data invalid, so it does not modify the MTime of this data object.

virtual void itk::DataObject::ReleaseDataFlagOff (    )  [virtual]

Turn on/off a flag to control whether this object's data is released after being used by a filter.

virtual void itk::DataObject::ReleaseDataFlagOn (    )  [virtual]

Turn on/off a flag to control whether this object's data is released after being used by a filter.

virtual bool itk::DataObject::RequestedRegionIsOutsideOfTheBufferedRegion (    )  [pure virtual]

Determine whether the RequestedRegion is outside of the BufferedRegion. This method returns true if the RequestedRegion is outside the BufferedRegion (true if at least one pixel is outside). This is used by the pipeline mechanism to determine whether a filter needs to re-execute in order to satisfy the current request. If the current RequestedRegion is already inside the BufferedRegion from the previous execution (and the current filter is up to date), then a given filter does not need to re-execute Implemented in itk::watershed::Boundary< TScalarType, TDimension >, itk::watershed::EquivalencyTable, itk::watershed::OneWayEquivalencyTable, itk::watershed::SegmentTable< TScalarType >, itk::watershed::SegmentTree< TScalarType >, itk::watershed::EquivalencyTable, itk::ImageBase< VImageDimension >, itk::Mesh< TPixelType, VDimension, TMeshTraits >, itk::watershed::OneWayEquivalencyTable, itk::PointSet< TPixelType, VDimension, TMeshTraits >, itk::SpatialObject< TDimension >, and itk::ImageBase< ::itk::GetImageDimension< TImage >::ImageDimension >.

virtual void itk::DataObject::ResetPipeline (    )  [virtual]

Reset the pipeline. If an exception is thrown during an Update(), the pipeline may be in an inconsistent state. This method clears the internal state of the pipeline so Update() can be called.

void itk::DataObject::SetGlobalReleaseDataFlag (  const bool    val )  [static]

Turn on/off a flag to control whether every object releases its data after being used by a filter. Being a global flag, it controls the behavior of all DataObjects and ProcessObjects.

bool itk::DataObject::ShouldIReleaseData (    )  const

Return flag indicating whether data should be released after use by a filter.

virtual void itk::DataObject::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 UpdateOutputInformation(), PropagateRequestedRegion(), and UpdateOutputData(). This method may call methods that throw an InvalidRequestedRegionError exception. This exception will leave the pipeline in an inconsistent state. You will need to call ResetPipeline() on the last ProcessObject in your pipeline in order to restore the pipeline to a state where you can call Update() again.

virtual void itk::DataObject::UpdateOutputData (    )  [virtual]

Methods to update the pipeline.

virtual void itk::DataObject::UpdateOutputInformation (    )  [pure virtual]

Update the information for this DataObject so that it can be used as an output of a ProcessObject. This method is used in the pipeline mechanism to propagate information and initialize the meta data associated with a DataObject. Any implementation of this method in a derived class is assumed to call its source's ProcessObject::UpdateOutputInformation() which determines modified times, LargestPossibleRegions, and any extra meta data like spacing, origin, etc. Implemented in itk::watershed::Boundary< TScalarType, TDimension >, itk::watershed::EquivalencyTable, itk::watershed::OneWayEquivalencyTable, itk::watershed::SegmentTable< TScalarType >, itk::watershed::SegmentTree< TScalarType >, itk::watershed::EquivalencyTable, itk::ImageAdaptor< TImage, TAccessor >, itk::ImageBase< VImageDimension >, itk::Mesh< TPixelType, VDimension, TMeshTraits >, itk::watershed::OneWayEquivalencyTable, itk::PointSet< TPixelType, VDimension, TMeshTraits >, itk::SpatialObject< TDimension >, itk::ImageAdaptor< TImage, Accessor::AsinPixelAccessor< TImage::PixelType, TOutputPixelType > >, itk::ImageAdaptor< TImage, Accessor::SqrtPixelAccessor< TImage::PixelType, TOutputPixelType > >, itk::ImageAdaptor< TImage, Accessor::TanPixelAccessor< TImage::PixelType, TOutputPixelType > >, itk::ImageAdaptor< TImage, Accessor::CosPixelAccessor< TImage::PixelType, TOutputPixelType > >, itk::ImageAdaptor< TImage, Accessor::VectorToRGBPixelAccessor< TImage::PixelType::ValueType > >, itk::ImageAdaptor< TImage, Accessor::RGBToVectorPixelAccessor< TImage::PixelType::ComponentType > >, itk::ImageAdaptor< TImage, Accessor::SinPixelAccessor< TImage::PixelType, TOutputPixelType > >, itk::ImageAdaptor< TImage, NthElementPixelAccessor< TOutputPixelType, TImage::PixelType > >, itk::ImageAdaptor< TImage, Accessor::LogPixelAccessor< TImage::PixelType, TOutputPixelType > >, itk::ImageAdaptor< TImage, Accessor::Log10PixelAccessor< TImage::PixelType, TOutputPixelType > >, itk::ImageAdaptor< TImage, Accessor::AtanPixelAccessor< TImage::PixelType, TOutputPixelType > >, itk::ImageAdaptor< TImage, Accessor::ExpNegativePixelAccessor< TImage::PixelType, TOutputPixelType > >, itk::ImageAdaptor< TImage, Accessor::ExpPixelAccessor< TImage::PixelType, TOutputPixelType > >, itk::ImageAdaptor< TImage, Accessor::AcosPixelAccessor< TImage::PixelType, TOutputPixelType > >, itk::ImageAdaptor< TImage, Accessor::AddPixelAccessor< TImage::PixelType > >, and itk::ImageBase< ::itk::GetImageDimension< TImage >::ImageDimension >.

virtual bool itk::DataObject::VerifyRequestedRegion (    )  [pure virtual]

Verify that the RequestedRegion is within the LargestPossibleRegion. If the RequestedRegion is not within the LargestPossibleRegion, then the filter cannot possibly satisfy the request. This method returns true if the request can be satisfied (even if it will be necessary to process the entire LargestPossibleRegion) and returns false otherwise. This method is used by PropagateRequestedRegion(). PropagateRequestedRegion() throws a InvalidRequestedRegionError exception if the requested region is not within the LargestPossibleRegion. Implemented in itk::watershed::Boundary< TScalarType, TDimension >, itk::watershed::EquivalencyTable, itk::watershed::OneWayEquivalencyTable, itk::watershed::SegmentTable< TScalarType >, itk::watershed::SegmentTree< TScalarType >, itk::watershed::EquivalencyTable, itk::ImageBase< VImageDimension >, itk::Mesh< TPixelType, VDimension, TMeshTraits >, itk::watershed::OneWayEquivalencyTable, itk::PointSet< TPixelType, VDimension, TMeshTraits >, itk::SpatialObject< TDimension >, and itk::ImageBase< ::itk::GetImageDimension< TImage >::ImageDimension >.
