Class \Prado\IO\TOutputWriter

TOutputWriter class.

TOutputWriter extends TTextWriter to write the buffer to "Output" when flushed. In a CLI execution, STDOUT is "Output" but this is not true for processing web pages. For web pages, "Output" goes to the browser and 'php://stdout' goes to the web server's output (either cli or file); while STDOUT is not defined.

Once this class is flushed, PHP's flush need to be called to ensure the "Output" is written. If Output Buffering (ob_*) is used, ob_flush (or equivalent) also must be called before PHP's flush and after this class flushes.
