Detailed Description

helper superclass for objects that read vtk data files

vtkDataReader is a helper superclass that reads the vtk data file header, dataset type, and attribute data (point and cell attributes such as scalars, vectors, normals, etc.) from a vtk data file. See text for the format of the various vtk file types.

Reimplemented in vtkUnstructuredGridReader, vtkTreeReader, vtkTableReader, vtkStructuredPointsReader, vtkStructuredGridReader, vtkRectilinearGridReader, vtkPolyDataReader, vtkGraphReader, vtkGenericDataObjectReader, and vtkDataSetReader.

◆ SetFileName()

void vtkDataReader::SetFileName ( VTK_FILEPATH const char *  fname)

This is just a convenience method that calls the superclass' AddFileName method.

◆ GetFileName() [1/2]

(In the case of VTK legacy files, see vtkDataWriter.h for the enum types returned.) This method only returns useful information after a successful read is performed; and some derived classes may not return relevant information.) Note that for VTK legacy readers, the FileVersion is defined by the compositing the major version digits with the minor version digit. Extremely ancient VTK files (e.g., before version 4.2) will return a FileVersion of 3.0.

Note that for VTK legacy readers, the FileVersion is defined by the compositing the major version digits with the minor version digit. Extremely ancient VTK files (e.g., before version 4.2) will return a FileVersion of 3.0.

◆ GetFileMinorVersion()

Optionally include the length for binary strings. Note that a copy of the string is made and stored. If this causes exceedingly large memory consumption, consider using InputArray instead.

◆ GetInputString()

virtual char* vtkDataReader::GetInputString ( )
virtual

Specify the InputString for use when reading from a character array.

Optionally include the length for binary strings. Note that a copy of the string is made and stored. If this causes exceedingly large memory consumption, consider using InputArray instead.

◆ SetInputString() [2/3]

void vtkDataReader::SetInputString ( const char *  in,
int  len

Specify the InputString for use when reading from a character array.

Optionally include the length for binary strings. Note that a copy of the string is made and stored. If this causes exceedingly large memory consumption, consider using InputArray instead.

void vtkDataReader::SetInputString ( const vtkStdString input)
inline

Specify the InputString for use when reading from a character array.

Optionally include the length for binary strings. Note that a copy of the string is made and stored. If this causes exceedingly large memory consumption, consider using InputArray instead.

Definition at line 113 of file vtkDataReader.h.

◆ SetInputArray()

virtual void vtkDataReader::SetInputArray ( vtkCharArray )
virtual

Specify the vtkCharArray to be used when reading from a string.

If set, this array has precedence over InputString. Use this instead of InputString to avoid the extra memory copy. It should be noted that if the underlying char* is owned by the user ( vtkCharArray::SetArray(array, 1); ) and is deleted before the reader, bad things will happen during a pipeline update.

◆ GetInputArray()

virtual vtkCharArray* vtkDataReader::GetInputArray ( )
virtual

Specify the vtkCharArray to be used when reading from a string.

If set, this array has precedence over InputString. Use this instead of InputString to avoid the extra memory copy. It should be noted that if the underlying char* is owned by the user ( vtkCharArray::SetArray(array, 1); ) and is deleted before the reader, bad things will happen during a pipeline update.

Get the type of file (ASCII or BINARY).

Returned value only valid after file has been read.

◆ GetNumberOfScalarsInFile()

int vtkDataReader::GetNumberOfScalarsInFile ( )
inline

How many attributes of various types are in this file? This requires reading the file, so the filename must be set prior to invoking this operation.

(Note: file characteristics are cached, so only a single read is necessary to return file characteristics.)
