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

◆ formatted_raw_ostream() [1/2]

llvm::formatted_raw_ostream::formatted_raw_ostream ( raw_ostream Stream)
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

◆ changeColor()

raw_ostream& llvm::formatted_raw_ostream::changeColor ( enum Colors  Color,
bool  Bold,
bool  BG 
)
inlineoverridevirtual

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

Parameters
ColorANSI color to use, the special SAVEDCOLOR can be used to change only the bold attribute, and keep colors untouched
Boldbold/brighter text, default false
BGif true change the background, default: change foreground
Returns
itself so it can be used within << invocations

Reimplemented from llvm::raw_ostream.

Definition at line 125 of file FormattedStream.h.

References llvm::raw_ostream::changeColor().

◆ getColumn()

unsigned llvm::formatted_raw_ostream::getColumn ( )
inline

getColumn - Return the column number

Definition at line 110 of file FormattedStream.h.

Referenced by PadToColumn().

◆ getLine()

unsigned llvm::formatted_raw_ostream::getLine ( )
inline

getLine - Return the line number

Definition at line 113 of file FormattedStream.h.

◆ is_displayed()

bool llvm::formatted_raw_ostream::is_displayed ( ) const
inlineoverridevirtual

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 130 of file FormattedStream.h.

References llvm::fdbgs(), llvm::ferrs(), llvm::fouts(), llvm::raw_ostream::GetBufferSize(), llvm::raw_ostream::is_displayed(), llvm::raw_ostream::SetBufferSize(), and llvm::raw_ostream::SetUnbuffered().

◆ PadToColumn()

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.
NewCol- The column to move to.

◆ resetColor()

raw_ostream& llvm::formatted_raw_ostream::resetColor ( )
inlineoverridevirtual

Resets the colors to terminal defaults.

Call this when you are done outputting colored text, or before program exit.

Reimplemented from llvm::raw_ostream.

Definition at line 115 of file FormattedStream.h.

References llvm::raw_ostream::resetColor().

◆ reverseColor()

raw_ostream& llvm::formatted_raw_ostream::reverseColor ( )
inlineoverridevirtual

Reverses the foreground and background colors.

Reimplemented from llvm::raw_ostream.
