// .NAME vtkWriter - abstract class to write data to file(s)
|
|
// .SECTION Description
|
|
// vtkWriter is an abstract class for mapper objects that write their data
|
|
// to disk (or into a communications port). All writers respond to Write()
|
|
// method. This method insures that there is input and input is up to date.
|
|
//
|
|
// Since vtkWriter is a subclass of vtkProcessObject, StartMethod(),
|
|
// EndMethod(), and ProgressMethod() are all available to writers.
|
|
// These methods are executed before and after execution of the Write()
|
|
// method. You can also specify arguments to these methods.
|
|
|
|
// .SECTION Caveats
|
|
// Every subclass of vtkWriter must implement a WriteData() method. Most likely
|
|
// will have to create SetInput() method as well.
|
|
|
