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().

Constructor & Destructor Documentation

◆  raw_svector_ostream()

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

Construct a new raw_svector_ostream.

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

◆  flush()

◆  reserveExtraSpace()

void llvm::raw_svector_ostream::reserveExtraSpace ( uint64_t ExtraSize )
inlineoverridevirtual

If possible, pre-allocate ExtraSize bytes for stream data.

i.e. it extends internal buffers to keep additional ExtraSize bytes. So that the stream could keep at least tell() + ExtraSize bytes without re-allocations. reserveExtraSpace() does not change the size/data of the stream.

Reimplemented from llvm::raw_ostream.
