virtual size_t | preferred_buffer_size () const |
Return an efficient buffer size for the underlying output mechanism. | |
const char * | getBufferStart () const |
Return the beginning of the current stream buffer, or 0 if the stream is unbuffered. More... | |
This class implements an extremely fast bulk output stream that can only output to a stream.
It does not support seeking, reopening, rewinding, line buffered disciplines etc. It is a simple buffer that outputs a chunk at a time.
|
inlinevirtual |
Changes the foreground color of text that will be output from this point forward.
Color | ANSI color to use, the special SAVEDCOLOR can be used to change only the bold attribute, and keep colors untouched |
Bold | bold/brighter text, default false |
BG | if true change the background, default: change foreground |
|
inlineprotected |
Return the beginning of the current stream buffer, or 0 if the stream is unbuffered.
|
inlinevirtual |
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.
|
inlinevirtual |
Resets the colors to terminal defaults.
Call this when you are done outputting colored text, or before program exit.
|
inlineprotected |
Use the provided buffer as the raw_ostream buffer.
This is intended for use only by subclasses which can arrange for the output to go directly into the desired output buffer, instead of being copied on each flush.
void wpi::raw_ostream::SetBuffered | ( | ) |
Set the stream to be buffered, with an automatically determined buffer size.
|
inline |
Set the stream to be unbuffered.
When unbuffered, the stream will flush after every write. This routine will also flush the buffer immediately when the stream is being set to unbuffered.
raw_ostream& wpi::raw_ostream::write_escaped | ( | StringRef | Str, |
bool | UseHexEscapes = false |
||
) |
Output Str
, turning '\', '', '
', '"', and anything that doesn't satisfy std::isprint into an escape sequence.
