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.
|
Close the vtk file. |
|
Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkSource. Reimplemented in vtkDataObjectReader. |
|
Get the type of file (ASCII or BINARY). Returned value only valid after file has been read. |
|
Get the header from the vtk data file. |
|
Return the istream being used to read in the data. |
|
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.) |
|
What is the name of the ith attribute of a certain type in this file? This requires reading the file, so the filename must be set prior to invoking this operation. |
|
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 vtkSource. Reimplemented in vtkDataObjectReader. |
|
Is the file a valid vtk file of the passed dataset type ? The dataset type is passed as a lower case string. |
|
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. Reimplemented from vtkSource. Reimplemented in vtkDataObjectReader. |
|
Helper method for reading in data. |
|
Instantiate object with no start, end, or progress methods. Reimplemented from vtkSource. Reimplemented in vtkDataObjectReader. |
|
Open a vtk data file. Returns zero if error. |
|
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 vtkSource. Reimplemented in vtkDataObjectReader. |
|
Internal function to read in a value. Returns zero if there was an error. |
|
Helper functions for reading data. |
|
Read the cell data of a vtk data file. The number of cells (from the dataset) must match the number of cells defined in cell attributes (unless no geometry was defined). |
|
Read a piece of the cells (for streaming compliance) |
|
Read a bunch of "cells". Return 0 if error. |
|
Read the coordinates for a rectilinear grid. The axes parameter specifies which coordinate axes (0,1,2) is being read. |
|
Read the header of a vtk data file. Returns 0 if error. |
|
Internal function to read in a line up to 256 characters. Returns zero if there was an error. |
|
Read the point data of a vtk data file. The number of points (from the dataset) must match the number of points defined in point attributes (unless no geometry was defined). |
|
Read point coordinates. Return 0 if error. |
|
Internal function to read in a string up to 256 characters. Returns zero if there was an error. |
|
Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkSource. Reimplemented in vtkDataObjectReader. |
|
Set the name of the field data to extract. If not specified, uses first field data encountered in file. |
|
Specify file name of vtk data file to read. |
|
Set the name of the ghost level data to extract. If not specified, first ghost level data encountered is extracted. |
|
Specify the InputString for use when reading from a character array. Optionally include the length for binary strings. |
|
Set the name of the lookup table data to extract. If not specified, uses lookup table named by scalar. Otherwise, this specification supersedes. |
|
Set the name of the normal data to extract. If not specified, first normal data encountered is extracted. |
|
Enable reading from an InputString instead of the default, a file. |
|
Set the name of the scalar data to extract. If not specified, first scalar data encountered is extracted. |
|
Set the name of the texture coordinate data to extract. If not specified, first texture coordinate data encountered is extracted. |
|
Set the name of the tensor data to extract. If not specified, first tensor data encountered is extracted. |
|
Set the name of the vector data to extract. If not specified, first vector data encountered is extracted. |
