class raw_string_ostream
Declaration
class raw_string_ostream : public raw_ostream { /* full declaration omitted */ };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().

Methods
¶uint64_t current_pos() const
uint64_t current_pos() constDescription
Return the current position within the stream, not counting the bytes currently in the buffer.
Declared at: llvm/include/llvm/Support/raw_ostream.h:640
¶raw_string_ostream(std::string& O)
raw_string_ostream(std::string& O)Declared at: llvm/include/llvm/Support/raw_ostream.h:643
Parameters
- std::string& O
¶void reserveExtraSpace(uint64_t ExtraSize)
void reserveExtraSpace(uint64_t ExtraSize)Description
If possible, pre-allocate \p 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.
Declared at: llvm/include/llvm/Support/raw_ostream.h:652
Parameters
- uint64_t ExtraSize
¶std::string& str()
std::string& str()Description
Returns the string's reference. In most cases it is better to simply use the underlying std::string directly. TODO: Consider removing this API.
Declared at: llvm/include/llvm/Support/raw_ostream.h:650
¶void write_impl(const char* Ptr, size_t Size)
void write_impl(const char* Ptr, size_t Size)Description
See raw_ostream::write_impl.
Declared at: llvm/include/llvm/Support/raw_ostream.h:636
Parameters
- const char* Ptr
- size_t Size
