Member Function Documentation

void casa::GLLogIO::append	(	const char *	msg,
		uInt	nspaces = 0
	)

Append a line to buffer then add a newline.

msg is indented by nspaces spaces. msg may contain newline characters.

void casa::GLLogIO::clear

(

)

Deletes current buffer contents.

int casa::GLLogIO::glcheck

(

uInt

nspaces

)

Copies any current OpenGL error messages to internal buffer.

void casa::GLLogIO::indent

(

uInt

nspaces = 0

)

Adds nspaces to buffer.

void casa::GLLogIO::post

(

)

Copy internal buffer to output.

Then clear internal buffer.

Reimplemented from casa::LogIO.

void casa::GLLogIO::postString

(

)

If an output string exists, copy it to an output stream if it exists.

If the output stream doesn't exist, copy it to the LogIO object. The string is then cleared. Ignore if the string doesn't exist.

Referenced by casa::GLPixelCanvas::postString().

void casa::GLLogIO::postString

(

const String &

str

)

Copy string to either output stream or LogIO object.

The string is not cleared.

static void casa::GLLogIO::postToStream

(

Bool

useStream = False

)

[static]

Logging to standard AIPS++ disrupts trace formatting.

These routines allow redirecting or delaying output. NOTE: There is only 1 instance of the use iostream flag or String for all instances of GLLogIO.

Post messages to an iostream instead of LogIO object.

Referenced by casa::GLPixelCanvas::postToStream().

static void casa::GLLogIO::postToString

(

String *

str = NULL

)

[static]

Post messages to str for later use.

Disables if NULL. If str is non NULL, no output is done until postString is called. Replacing an existing string does not cause the existing string to be posted.

Referenced by casa::GLPixelCanvas::postToString().

void casa::GLLogIO::trace	(	const char *	name,
		int	nspaces,
		Bool	errorsonly = False
	)

Print tracing information.

Also calls glcheck. This is the main use for GLLogIO. nspaces is the number of spaces to indent name and any errors. If errorsonly is True, don't print anything if there are no errors.
