Detailed Description

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().

◆ raw_svector_ostream()

llvm::raw_svector_ostream::raw_svector_ostream ( SmallVectorImpl< char > &  O)

Construct a new raw_svector_ostream.

OThe vector to write to; this should generally have at least 128 bytes free to avoid any extraneous memory overhead.
