Description

The Log is used whenever the developer needs to write out debugging or tracing information to a file or console.

Common usecase:

Log(Log::ERR) << "Loading level:" << 1;

This enum defines the lavel of logging.

Constant	Value	Description
Log::CRT	0	Critical logging. For use with critical failures.
Log::ERR	1	Error logging. For use with unrecoverable failures.
Log::WRN	2	Warning logging. For use with recoverable failures.
Log::INF	3	Informational logging. Should be desabled in release.
Log::DBG	4	Debug logging. Should be desabled in release.

Methods Description

Log::Log (Log::LogTypes type)

Constructs a log stream that writes to the handler for the message type.

---

Log::~Log ()

Flushes any pending data to be written and destroys the log stream.

---

LogHandler * Log::handler ()

Returns LogHandler object if present; otherwise returns nullptr.

---

void Log::overrideHandler (LogHandler * handler)

Set a new Log handler. This method can be used in case if a developer would need to move logging stream to someplace. For example to the console.

---

void Log::setLogLevel (Log::LogTypes level)

Set current log level output. Messages wich are below this level will be descarded.

---

Log & Log::operator<< (bool b)

Writes the b*oolean value, *b, to the stream and returns a reference to the stream.

Log & Log::operator<< (char c)

Writes the singed 8 bit integer value, c, to the stream and returns a reference to the stream.

Log & Log::operator<< (char * string)

Writes the ‘0’-terminated string, to the stream and returns a reference to the stream.

Log & Log::operator<< (std::string & string)

Writes the text string, to the stream and returns a reference to the stream.

Log & Log::operator<< (void * value)

Writes the pointer value, to the stream and returns a reference to the stream.

Log & Log::operator<< (double d)

Writes the float value with d*ouble precision, *d, to the stream and returns a reference to the stream.

Log & Log::operator<< (float f)

Writes the f*loat value, *f, to the stream and returns a reference to the stream.

Log & Log::operator<< (int i)

Writes the singed 32 bit i*nteger value, *i, to the stream and returns a reference to the stream.

Log & Log::operator<< (long i)

Writes the singed 64 bit i*nteger value, *i, to the stream and returns a reference to the stream.

Log & Log::operator<< (short s)

Writes the s*inged 16 bit integer value, *s, to the *s*tream and returns a reference to the *s*tream.

Log & Log::operator<< (char c)

Writes the unsinged 8 bit integer value, c, to the stream and returns a reference to the stream.

Log & Log::operator<< (int i)

Writes the unsinged 32 bit i*nteger value, *i, to the stream and returns a reference to the stream.

Log & Log::operator<< (long i)

Writes the unsinged 64 bit i*nteger value, *i, to the stream and returns a reference to the stream.

Log & Log::operator<< (short s)

Writes the unsinged 16 bit integer value, s, to the *s*tream and returns a reference to the *s*tream.
