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.

Definition at line 707 of file raw_ostream.h.

classof()

bool raw_svector_ostream::classof ( const raw_ostream *  OS )

flush()

delete

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.

Definition at line 723 of file raw_ostream.h.

References OS, and llvm::raw_ostream::tell().

str()

StringRef llvm::raw_svector_ostream::str ( ) const

inline

Return a StringRef for the vector contents.
