Detailed Description

Reader for amr datasets (vtkOverlappingAMR or vtkNonOverlappingAMR).

vtkXMLUniformGridAMRReader reads the VTK XML data files for all types of amr datasets including vtkOverlappingAMR, vtkNonOverlappingAMR and the legacy vtkHierarchicalBoxDataSet. The reader uses information in the file to determine what type of dataset is actually being read and creates the output-data object accordingly.

This reader can only read files with version 1.1 or greater. Older versions can be converted to the newer versions using vtkXMLHierarchicalBoxDataFileConverter.

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkXMLCompositeDataReader.

virtual void vtkXMLUniformGridAMRReader::SetMaximumLevelsToReadByDefault ( unsigned int )

virtual

This reader supports demand-driven heavy data reading i.e. downstream pipeline can request specific blocks from the AMR using vtkCompositeDataPipeline::UPDATE_COMPOSITE_INDICES() key in RequestUpdateExtent() pass. However, when down-stream doesn't provide any specific keys, the default behavior can be setup to read at-most N levels by default. The number of levels read can be set using this method. Set this to 0 to imply no limit. Default is 0.

virtual unsigned int vtkXMLUniformGridAMRReader::GetMaximumLevelsToReadByDefault ( )

This reader supports demand-driven heavy data reading i.e. downstream pipeline can request specific blocks from the AMR using vtkCompositeDataPipeline::UPDATE_COMPOSITE_INDICES() key in RequestUpdateExtent() pass. However, when down-stream doesn't provide any specific keys, the default behavior can be setup to read at-most N levels by default. The number of levels read can be set using this method. Set this to 0 to imply no limit. Default is 0.

virtual int vtkXMLUniformGridAMRReader::CanReadFileWithDataType ( const char * dsname )

protectedvirtual

This method is used by CanReadFile() to check if the reader can read an XML with the primary element with the given name. Default implementation compares the name with the text returned by this->GetDataSetName(). Overridden to support all AMR types.

Reimplemented from vtkXMLReader.

virtual int vtkXMLUniformGridAMRReader::ReadVTKFile ( vtkXMLDataElement * eVTKFile )

protectedvirtual

Read the top-level element from the file. This is always the VTKFile element. Overridden to read the "type" information specified in the XML. The "type" attribute helps us identify the output data type.

Reimplemented from vtkXMLReader.

virtual int vtkXMLUniformGridAMRReader::ReadPrimaryElement ( vtkXMLDataElement * ePrimary )

protectedvirtual

Read the meta-data from the AMR from the file. Note that since ReadPrimaryElement() is only called when the filename changes, we are technically not supporting time-varying AMR datasets in this format right now.

Reimplemented from vtkXMLCompositeDataReader.

virtual int vtkXMLUniformGridAMRReader::RequestDataObject	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)

protectedvirtual

Overridden to create an output data object based on the type in the file. Since this reader can handle all subclasses of vtkUniformGrid, we need to check in the file to decide what type to create.

virtual int vtkXMLUniformGridAMRReader::RequestInformation	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)

protectedvirtual

Overridden to put vtkOverlappingAMR in the pipeline if available/applicable.

Reimplemented from vtkXMLCompositeDataReader.
