class circular_raw_ostream

Declaration

class circular_raw_ostream : public raw_ostream { /* full declaration omitted */ };

Description

circular_raw_ostream - A raw_ostream which *can* save its data to a circular buffer, or can pass it through directly to an underlying stream if specified with a buffer of zero.

Declared at: llvm/include/llvm/Support/circular_raw_ostream.h:24

Member Variables

public static const bool TAKE_OWNERSHIP = true
TAKE_OWNERSHIP - Tell this stream that it owns the underlying stream and is responsible for cleanup, memory management issues, etc.
public static const bool REFERENCE_ONLY = false
REFERENCE_ONLY - Tell this stream it should not manage the held stream.

Methods

circular_raw_ostream(llvm::raw_ostream& Stream,
                     const char* Header,
                     size_t BuffSize = 0,
                     bool Owns = REFERENCE_ONLY)

Description

circular_raw_ostream - Construct an optionally circular-buffered stream, handing it an underlying stream to do the "real" output. As a side effect, if BuffSize is nonzero, the given Stream is set to be Unbuffered. This is because circular_raw_ostream does its own buffering, so it doesn't want another layer of buffering to be happening underneath it. "Owns" tells the circular_raw_ostream whether it is responsible for managing the held stream, doing memory management of it, etc.

Declared at: llvm/include/llvm/Support/circular_raw_ostream.h:107

Parameters

llvm::raw_ostream& Stream
const char* Header
size_t BuffSize = 0
bool Owns = REFERENCE_ONLY

void flushBufferWithBanner()

Description

flushBufferWithBanner - Force output of the buffer along with a small header.

Declared at: llvm/include/llvm/Support/circular_raw_ostream.h:143

bool is_displayed() const

Description

This function determines if this stream is connected to a "tty" or "console" window. That is, the output would be displayed to the user rather than being put on a pipe or stored in a file.

Declared at: llvm/include/llvm/Support/circular_raw_ostream.h:125

void setStream(llvm::raw_ostream& Stream,
               bool Owns = REFERENCE_ONLY)

Description

setStream - Tell the circular_raw_ostream to output a different stream. "Owns" tells circular_raw_ostream whether it should take responsibility for managing the underlying stream.

Declared at: llvm/include/llvm/Support/circular_raw_ostream.h:134

Parameters

llvm::raw_ostream& Stream
bool Owns = REFERENCE_ONLY

~circular_raw_ostream()
