// .NAME vtkOStrStreamWrapper - Wrapper for ostrstream. Internal VTK use only.
|
|
// .SECTION Description
|
|
// 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.
