/**

|
* @class vtkOStrStreamWrapper
|
||
|
|
* @brief Wrapper for ostrstream. Internal VTK use only.
|
||
|
|
*
|
||
|
|
* Provides a wrapper around the C++ ostrstream class so that VTK
|
||
|
|
* source files need not include the full C++ streams library. This
|
||
|
|
* is intended to prevent cluttering of the translation unit and speed
|
||
|
|
* up compilation. Experimentation has revealed between 10% and 60%
|
||
|
|
* less time for compilation depending on the platform. This wrapper
|
||
|
|
* is used by the macros in vtkSetGet.h.
