Protected Member Functions inherited from llvm::raw_ostream
void SetBuffer (char *BufferStart, size_t Size)
Use the provided buffer as the raw_ostream buffer.
virtual size_t preferred_buffer_size () const
Return an efficient buffer size for the underlying output mechanism.
const char * getBufferStart () const
Return the beginning of the current stream buffer, or 0 if the stream is unbuffered.

A raw_ostream that writes to an SmallVector or SmallString.

This is a simple adaptor class. This class does not encounter output errors. raw_svector_ostream operates without a buffer, delegating all memory management to the SmallString. Thus the SmallString is always up-to-date, may be used directly and there is no need to call flush().
