Detailed Description

formatted_raw_ostream - A raw_ostream that wraps another one and keeps track of line and column position, allowing padding out to specific column boundaries and querying the number of lines written to the stream.

Definition at line 27 of file FormattedStream.h.

Constructor & Destructor Documentation

llvm::formatted_raw_ostream::formatted_raw_ostream	(	raw_ostream &	Stream,
		bool	Delete = `false`
	)		`[inline]`

formatted_raw_ostream - Open the specified file for writing. If an error occurs, information about the error is put into ErrorInfo, and the stream should be immediately destroyed; the string will be empty if no error occurred.

As a side effect, the given Stream is set to be Unbuffered. This is because formatted_raw_ostream does its own buffering, so it doesn't want another layer of buffering to be happening underneath it.

Member Function Documentation

raw_ostream& llvm::formatted_raw_ostream::changeColor	(	enum Colors	Color,
		bool	Bold,
		bool	BG
	)		`[inline, override, virtual]`

Changes the foreground color of text that will be output from this point forward.

Parameters:

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

Returns:: itself so it can be used within << invocations

unsigned llvm::formatted_raw_ostream::getColumn ( ) [inline]

getColumn - Return the column number

Definition at line 128 of file FormattedStream.h.

unsigned llvm::formatted_raw_ostream::getLine ( ) [inline]

getLine - Return the line number

Definition at line 131 of file FormattedStream.h.

bool llvm::formatted_raw_ostream::is_displayed ( ) const [inline, override, virtual]

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.

Reimplemented from llvm::raw_ostream.

Definition at line 148 of file FormattedStream.h.

References llvm::raw_ostream::is_displayed().

formatted_raw_ostream & formatted_raw_ostream::PadToColumn ( unsigned NewCol )

PadToColumn - Align the output to some column number. If the current column is already equal to or more than NewCol, PadToColumn inserts one space.

Parameters:

NewCol - The column to move to.

PadToColumn - Align the output to some column number.

Parameters:

NewCol - The column to move to.
