Detailed Description

LogOrigin: The source code location of the originator of a LogMessage.

Intended use:

Public interface

Review Status

Prerequisite

ObjectID if you are interested in logging from Distributed Objects (don't worry if you don't know what that means - in that case ignore it!).

Etymology

Log[message] Origin[ation point].

Synopsis

The LogOriging class is used to record the location at which a LogMessage originates. It consists of:

A class name, which is blank in the case of a global function.
A function name - global or member. You should "cut and paste" not only the function name, but also the arguments (but not the return type) to ensure that the function name is unique in the face of overloading.
A source file name, usually filled in with the WHERE predefined macro.
A line number, usually filled in with the LINE or WHERE macros.
An ObjectID if the log message comes from a distributed object (if you don't know what this means, you don't need to worry about it).
Eventually we may want to canonicalize the path in the filename.

Example

See the examples for LogMessage and in (see (file="Logging.h"))Logging.h.

Motivation

It can be very useful for debugging if you know where a message is coming from.

Constructor & Destructor Documentation

◆ LogOrigin() [1/5]

casacore::LogOrigin::LogOrigin ( )

The default constructor sets a null class name, function name, object id, source file name, and sets the line number to zero.

◆ LogOrigin() [2/5]

casacore::LogOrigin::LogOrigin	(	const String &	globalFunctionName,
		const SourceLocation *	where = `0`
	)

Use this constructor if the log message origination is from a global function.

Normally where is provided using the WHERE macro.

◆ LogOrigin() [3/5]

casacore::LogOrigin::LogOrigin	(	const String &	className,
		const String &	memberFuncName,
		const SourceLocation *	where = `0`
	)

Use this constructor if the log message origination is from a class member function.

Normally where is provided using the WHERE macro.

◆ LogOrigin() [4/5]

casacore::LogOrigin::LogOrigin	(	const String &	className,
		const String &	memberFuncName,
		const ObjectID &	id,
		const SourceLocation *	where = `0`
	)

Use this constructor if the log message origination is from a distributed object (don't worry if you don't know what this means).

Normally where is provided using the WHERE macro.

◆ LogOrigin() [5/5]

casacore::LogOrigin::LogOrigin ( const LogOrigin & other )

Make this LogOrigin a copy of other.

◆ ~LogOrigin()

casacore::LogOrigin::~LogOrigin ( )

Member Function Documentation

◆ className() [2/2]

LogOrigin& casacore::LogOrigin::className ( const String & className )

◆ copy_other()

void casacore::LogOrigin::copy_other ( const LogOrigin & other )

private

Provide common implementation for copy constructor and assignment operator.

◆ fileName() [1/2]

const String& casacore::LogOrigin::fileName ( ) const

◆ fileName() [2/2]

LogOrigin& casacore::LogOrigin::fileName ( const String & fileName )

◆ fullName()

String casacore::LogOrigin::fullName ( ) const

Returns class::function for a member function, or ::function for a global function.

◆ functionName() [1/2]

const String& casacore::LogOrigin::functionName ( ) const

◆ functionName() [2/2]

LogOrigin& casacore::LogOrigin::functionName ( const String & funcName )

◆ getNode()

String casacore::LogOrigin::getNode ( )

private

Return a String with the MPI rank.

◆ isUnset()

Bool casacore::LogOrigin::isUnset ( ) const

Return true if the line number and file name are not set.

◆ line() [1/2]

uInt casacore::LogOrigin::line ( ) const

◆ line() [2/2]

LogOrigin& casacore::LogOrigin::line ( uInt which )

◆ location()

String casacore::LogOrigin::location ( ) const

Turns the entire origin except for the ObjectID into a String.

The ObjectID can be turned into a string vie ObjectID::toString.

◆ objectID() [1/2]

const ObjectID& casacore::LogOrigin::objectID ( ) const

◆ objectID() [2/2]

LogOrigin& casacore::LogOrigin::objectID ( const ObjectID & id )

◆ operator=()

LogOrigin& casacore::LogOrigin::operator= ( const LogOrigin & other )

◆ sourceLocation()

LogOrigin& casacore::LogOrigin::sourceLocation ( const SourceLocation * where )

Set the file name and line number at the same time.

Normally where will be defined with the WHERE macro.

◆ taskName() [1/2]

const String& casacore::LogOrigin::taskName ( ) const

Get or set the corresponding element of the source location.

Note that the "set" functions can be strung together:

 LogOrigin where;
..\.
 where.function("anotherFunc").line(__LINE__);

◆ taskName() [2/2]

LogOrigin& casacore::LogOrigin::taskName ( const String & funcName )

◆ toString()

String casacore::LogOrigin::toString ( ) const

Turn the entire origin into a String.
