Detailed Description

template<ThreadSafety SAFETY>
class ts::ReportFile< SAFETY >

A subclass of ts::Report which outputs messages in a text file.

Reentrancy is supported though the template parameter SAFETY.

Template Parameters

SAFETY The required type of thread-safety.

Constructor & Destructor Documentation

◆ ReportFile() [1/2]

template<ts::ThreadSafety SAFETY>

ts::ReportFile< SAFETY >::ReportFile	(	const fs::path &	file_name,
		bool	append = `false`,
		int	max_severity = `Severity::Info`
	)

Constructor using a named file.

Parameters

[in]	file_name	The name of the file to create. If the file creation fails, a fatal error is generated with an error message on std::cerr. The file will be closed when this object is destroyed.
[in]	append	If true, append the messages at the end of the file. If false (the default), overwrite the file if it already existed.
[in]	max_severity	Maximum debug level to display. None by default.

◆ ReportFile() [2/2]

template<ts::ThreadSafety SAFETY>

ts::ReportFile< SAFETY >::ReportFile	(	std::ostream &	stream,
		int	max_severity = `0`
	)

Constructor using an open file stream.

Parameters

[in,out]	stream	A reference to an open output file stream to log the messages. The corresponding stream object must remain valid as long as this object exists. Typical valid values are std::cout and std::cerr.
[in]	max_severity	Maximum debug level to display. None by default.

Member Function Documentation

◆ writeLog()

template<ts::ThreadSafety SAFETY>

void ts::ReportFile< SAFETY >::writeLog	(	int	severity,
		const UString &	msg
	)

overrideprotectedvirtual

Actual message reporting method.

The method is called only when a message passed the severity filter. It is not necessary to recheck the maximum severity inside the method. By default, does nothing.

Parameters

[in]	severity	Message severity.
[in]	msg	Message text.

Reimplemented from ts::Report.

◆ setMaxSeverity()

void ts::Report::setMaxSeverity ( int level )

inherited

Set maximum severity level.

Messages with higher severities are not reported.

Parameters

[in] level Set report to that level.

◆ raiseMaxSeverity()

void ts::Report::raiseMaxSeverity ( int level )

inherited

Raise maximum severity level.

The severity can only be increased (more verbose, more debug), never decreased.

Parameters

[in] level Set report at least to that level.

◆ maxSeverity()

int ts::Report::maxSeverity ( ) const

inlineinherited

Get maximum severity level.

Returns: Current maximum debug level.

◆ gotErrors()

bool ts::Report::gotErrors ( ) const

inlineinherited

Check if errors (or worse) were reported through this object.

Errors which were reported through delegated reports are ignored.

Returns: True if errors (or worse) were reported through this object.

◆ resetErrors()

inlineinherited

Reset the error indicator.

Returns: The current prefix to display.

◆ delegateReport()

Report * ts::Report::delegateReport ( Report * report )

inherited

Delegate message logging to another report object.

Parameters

[in] report New report object to which messages are delegated. Use nullptr to remove the delegation and return to normal logging.

Returns: Previous delegate report, return a null pointer if there was no previous delegate.
