Member Function Documentation

ctrl()

void SlHelpers::Color::ctrl ( Ctrl  ctrl )

inline

Controls the stream behavior.

Parameters

ctrl	Control character (like NoNL to not automatically emit a newline at the end)

forceColor()

static void SlHelpers::Color::forceColor ( bool  force )

inlinestatic

Force color value (see forceColorValue())

Parameters

force

If set, use of colors is bound to color value set by forceColorValue()

forceColorValue()

static void SlHelpers::Color::forceColorValue ( bool  value )

inlinestatic

If forceColor(true) was called, use of colors is bound to value.

Parameters

value

If colors should be used

os()

std::ostream& SlHelpers::Color::os ( )

inline

Return current output stream.

Returns

Output stream.
