Detailed Description
A raw_ostream that writes to an std::string.
This is a simple adaptor class. This class does not encounter output errors. raw_string_ostream operates without a buffer, delegating all memory management to the std::string. Thus the std::string is always up-to-date, may be used directly and there is no need to call flush().

Member Function Documentation
◆ reserveExtraSpace()
|
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 651 of file raw_ostream.h.
References llvm::raw_ostream::tell().
◆ str()
|
inline |
Returns the string's reference.
In most cases it is better to simply use the underlying std::string directly. TODO: Consider removing this API.
