Detailed Description

Reads data saved using the VTK HDF format which supports all vtkDataSet types (image data, poly data, unstructured grid, overlapping AMR, partitioned dataset collection and multiblock are currently implemented) and serial as well as parallel processing.

Read VTK HDF files.

Can also read temporal data with directions and offsets present in a supplemental 'VTKHDF/Steps' group for vtkUnstructuredGrid vtkPolyData, and vtkImageData.

Major version should be incremented when older readers can no longer read files written for this reader. Minor versions are for added functionality that can be safely ignored by older readers.

Note: vtkHDF file format is defined here : https://docs.vtk.org/en/latest/design_documents/VTKFileFormats.html#hdf-file-formats

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.

Reimplemented from vtkDataObjectAlgorithm.

◆ SafeDownCast()

◆ NewInstanceInternal()

◆ PrintSelf()

void vtkHDFReader::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

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 vtkDataObjectAlgorithm.

◆ vtkSetFilePathMacro()

vtkHDFReader::vtkSetFilePathMacro ( FileName )

Get/Set the name of the input file.

◆ vtkGetFilePathMacro()

Get/Set the name of the input file.

◆ CanReadFile()

virtual int vtkHDFReader::CanReadFile ( VTK_FILEPATH const char * name )

Test whether the file (type) with the given name can be read by this reader.

If the file has a newer version than the reader, we still say we can read the file type and we fail later, when we try to read the file. This enables clients (ParaView) to distinguish between failures when we need to look for another reader and failures when we don't.

◆ GetUseCache()

virtual bool vtkHDFReader::GetUseCache ( )

virtual

Boolean property determining whether to use the internal cache or not (default is false).

Internal cache is useful when reading temporal data to never re-read something that has already been cached.

Note: Incompatible with MergeParts as vtkAppendDataSet which is used internally doesn't support static mesh.

◆ SetUseCache()

virtual

Merging partitions (true) allows the reader to return either vtkUnstructuredGrid or vtkPolyData directly while not merging (false) them returns a vtkPartitionedDataSet. It is advised to set this value to false when using the internal cache (UseCache == true) since the partitions are what are stored in the cache and merging them before outputting would effectively double the memory constraints.

Default is true

Note: Incompatible with UseCache as vtkAppendDataSet which is used internally doesn't support static mesh.
