Detailed Description

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.

Constructor & Destructor Documentation

◆ vtkOStrStreamWrapper()

vtkOStrStreamWrapper::vtkOStrStreamWrapper ( )

Constructor.

◆ ~vtkOStrStreamWrapper()

vtkOStrStreamWrapper::~vtkOStrStreamWrapper ( )
override

Destructor frees all used memory.

Member Function Documentation

◆ str()

char* vtkOStrStreamWrapper::str ( )

Get the string that has been written.

This call transfers ownership of the returned memory to the caller. Call rdbuf()->freeze(0) to return ownership to the vtkOStrStreamWrapper.

◆ rdbuf()

vtkOStrStreamWrapper* vtkOStrStreamWrapper::rdbuf ( )

Returns a pointer to this class.

This is a hack so that the old ostrstream's s.rdbuf()->freeze(0) can work.

◆ freeze() [1/2]

void vtkOStrStreamWrapper::freeze ( )

Set whether the memory is frozen.

The vtkOStrStreamWrapper will free the memory returned by str() only if it is not frozen.

◆ freeze() [2/2]

void vtkOStrStreamWrapper::freeze ( int  )

Member Data Documentation

◆ Result

char* vtkOStrStreamWrapper::Result

◆ Frozen
