a simple class to control print indentation
Definition: vtkIndent.h:38
Store zero or more vtkInformation instances.
Store vtkAlgorithm input/output information.
Read ASCII or binary particle data and (optionally) one scalar value associated with each particle.
void SetDataByteOrder(int)
These methods should be used instead of the SwapBytes methods.
size_t Count
Count of the number of alliquots processed.
size_t Alliquot
Set an alliquot of bytes.
int ProduceOutputFromBinaryFileDouble(vtkInformationVector *outputVector)
This reader assumes that the file is binary and consists of floating point values by default.
int GetDataByteOrder()
These methods should be used instead of the SwapBytes methods.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
int RequestInformation(vtkInformation *, vtkInformationVector **, vtkInformationVector *) override
int RequestData(vtkInformation *, vtkInformationVector **, vtkInformationVector *) override
This is called by the superclass.
vtkTypeBool GetSwapBytes()
Set/Get the byte swapping to explicitly swap the bytes of a file.
int ProduceOutputFromTextFileDouble(vtkInformationVector *outputVector)
The format that will be read if the file is a text file is: x, y, z, s (where s is some scalar value ...
void SetFileTypeToText()
Get/Set the file type.
vtkGetFilePathMacro(FileName)
Specify file name.
int FileType
Used to decide which reader should be used.
static vtkParticleReader * New()
vtkSetFilePathMacro(FileName)
Specify file name.
int ProduceOutputFromTextFileFloat(vtkInformationVector *outputVector)
The format that will be read if the file is a text file is: x, y, z, s (where s is some scalar value ...
int DetermineFileType()
Determine the type of file based on an analysis of its contents.
FILE_TYPE
Enumerate the supported file types.
void SetDataByteOrderToLittleEndian()
These methods should be used instead of the SwapBytes methods.
void SetDataTypeToDouble()
Get/Set the data type.
void SetFileTypeToBinary()
Get/Set the file type.
void DoProgressUpdate(size_t &bytesRead, size_t &fileLength)
Update of the progress.
void SetDataTypeToFloat()
Get/Set the data type.
~vtkParticleReader() override
const char * GetDataByteOrderAsString()
These methods should be used instead of the SwapBytes methods.
int DataType
Used to specify the data type.
int ProduceOutputFromBinaryFileFloat(vtkInformationVector *outputVector)
This reader assumes that the file is binary and consists of floating point values by default.
void SetFileTypeToUnknown()
Get/Set the file type.
void SetDataByteOrderToBigEndian()
These methods should be used instead of the SwapBytes methods.
Superclass for algorithms that produce only polydata as output.
