/**

|
|
* @brief abstract class to write data to file(s)
|
|
*
|
|
* 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.
|
|
*
|
|
* @warning
|
|
* Every subclass of vtkWriter must implement a WriteData() method. Most likely
|
|
* will have to create SetInput() method as well.
