Constructor & Destructor Documentation

Sawyer::Message::Prefix::Prefix ( )

inlineprotected

Constructor for derived classes.

Non-subclass users should use instance instead.

Definition at line 1011 of file Message.h.

Member Function Documentation

static PrefixPtr Sawyer::Message::Prefix::instance ( )

inlinestatic

Allocating constructor.

Creates a new prefix instance and returns a pointer to it. The new object is initialized with information about the thread that created it, such as program name, thread ID, time of creation, etc.

Definition at line 1024 of file Message.h.

Referenced by Sawyer::Message::UnformattedSink::UnformattedSink().

static PrefixPtr Sawyer::Message::Prefix::silentInstance ( )

static

Construct a prefix that is silent.

Constructs a prefix whose output properties are all false, thus producing no output.

const ColorSet& Sawyer::Message::Prefix::colorSet ( ) const

inline

Property: colors to use for the prefix if coloring is enabled.

Colors can be specified even for sinks that don't support them–they just won't be used.

Thread safety: Not thread-safe.

Definition at line 1038 of file Message.h.

ColorSet& Sawyer::Message::Prefix::colorSet ( )

inline

Property: colors to use for the prefix if coloring is enabled.

Colors can be specified even for sinks that don't support them–they just won't be used.

Thread safety: Not thread-safe.

Definition at line 1039 of file Message.h.

const Optional<std::string>& Sawyer::Message::Prefix::programName ( ) const

inline

Property: program name.

The default is the base name of the file that was executed. An "lt-" prefix is removed from the base name since this is typically added by libtool and doesn't correspond to the name that the user executed.

Thread safety: Not thread safe.

See also: setProgramName showProgramName

Definition at line 1052 of file Message.h.

PrefixPtr Sawyer::Message::Prefix::programName ( const std::string & s )

inline

Property: program name.

The default is the base name of the file that was executed. An "lt-" prefix is removed from the base name since this is typically added by libtool and doesn't correspond to the name that the user executed.

Thread safety: Not thread safe.

See also: setProgramName showProgramName

Definition at line 1053 of file Message.h.

void Sawyer::Message::Prefix::setProgramName ( )

Reset the program name from operating system information.

Thread safety: This method is thread-safe.

See also: programName showProgramName

bool Sawyer::Message::Prefix::showProgramName ( ) const

inline

Property: whether to show the program name in the message prefix area.

The default is true.

Thread safety: This method is not thread-safe.

See also: programName

Definition at line 1071 of file Message.h.

PrefixPtr Sawyer::Message::Prefix::showProgramName ( bool b )

inline

Property: whether to show the program name in the message prefix area.

The default is true.

Definition at line 1072 of file Message.h.

bool Sawyer::Message::Prefix::showThreadId ( ) const

inline

Property: whether to show the thread ID in the message prefix area.

The default is true.

Thread safety: This method is not thread-safe.

Definition at line 1082 of file Message.h.

Definition at line 1083 of file Message.h.

const Optional<double> Sawyer::Message::Prefix::startTime ( ) const

Property: start time when emitting time deltas.

On some systems the start time will be the time at which this object was created.

Thread safety: This method is not thread-safe.

See also: setStartTime showElapsedTime

PrefixPtr Sawyer::Message::Prefix::startTime ( double t )

Property: start time when emitting time deltas.

On some systems the start time will be the time at which this object was created.

Thread safety: This method is not thread-safe.

See also: setStartTime showElapsedTime

void Sawyer::Message::Prefix::setStartTime ( )

Reset the start time from operating system information.

On some systems this will be the time at which the first prefix object was created rather than the time the operating system created the main process.

Thread safety: This method is not thread-safe.

See also: startTime showElapsedTime

bool Sawyer::Message::Prefix::showElapsedTime ( ) const

inline

Property: whether to show time deltas.

Time deltas are displayed as fractional seconds since some starting time.

Thread safety: This method is not thread-safe.

When Sawyer::Message::Prefix::showFacilityName ( ) const

inline

Property: whether to show the facilityName property.

When set to SOMETIMES, the facility name is shown when it differs from the program name and the program name has been shown. In any case, the facility name is not shown if it has no value.
