Reader for amr datasets (vtkOverlappingAMR or vtkNonOverlappingAMR). More...
#include <vtkXMLUniformGridAMRReader.h>
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.

| static vtkXMLUniformGridAMRReader* vtkXMLUniformGridAMRReader::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkAlgorithm.
Reimplemented in vtkXMLHierarchicalBoxDataReader.
| static int vtkXMLUniformGridAMRReader::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type 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 int vtkXMLUniformGridAMRReader::IsA | ( | const char * | name | ) | [virtual] |
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.

| void vtkXMLUniformGridAMRReader::PrintSelf | ( | ostream & | os, |
| vtkIndent | indent | ||
| ) | [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.

| 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 int vtkXMLUniformGridAMRReader::CanReadFileWithDataType | ( | const char * | dsname | ) | [protected, virtual] |
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 | ) | [protected, virtual] |
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 | ) | [protected, virtual] |
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 | ||
| ) | [protected, virtual] |
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 | ||
| ) | [protected, virtual] |
Overridden to put vtkOverlappingAMR in the pipeline if available/applicable.
Reimplemented from vtkXMLCompositeDataReader.
| virtual const char* vtkXMLUniformGridAMRReader::GetDataSetName | ( | ) | [protected, virtual] |
Reimplemented from vtkXMLCompositeDataReader.
| virtual void vtkXMLUniformGridAMRReader::ReadComposite | ( | vtkXMLDataElement * | element, |
| vtkCompositeDataSet * | composite, | ||
| const char * | filePath, | ||
| unsigned int & | dataSetIndex | ||
| ) | [protected, virtual] |
Implements vtkXMLCompositeDataReader.
