Enumeration Type Documentation

enum einhard::LogLevel

Specification of the message severity.

In output each level automatically includes the higher levels.

Enumerator
ALL	Log all message.
TRACE	The lowes severity for messages describing the program flow.
DEBUG	Debug messages.
INFO	Messages of informational nature, expected processing time e.g.
WARN	Warning messages.
ERROR	Non-fatal errors.
FATAL	Messages that indicate terminal application failure.
OFF	If selected no messages will be output.

Definition at line 104 of file einhard.hpp.

Function Documentation

template<LogLevel >

const char* einhard::getLogLevelString ( )

noexcept

Retrieve a human readable representation of the given log level value.

The overload can optimize better because it can determine the LogLevel at compile time.

Here is the caller graph for this function:

const char* einhard::getLogLevelString ( LogLevel level )

Overload of the above function for situations where the LogLevel level is only determined at run time.

LogLevel einhard::getLogLevel ( const std::string & level )

Compares the string level against the strings for LogLevel and returns the one it matches.

Parameters

level A string, which is a textual representation of one of the LogLevel enumerators.

Returns: The enumerator that matches the input string.

Exceptions

std::invalid_argument if the string does not match any enumerator.

Here is the caller graph for this function:

template<LogLevel >

const char* einhard::colorForLogLevel ( )

noexcept

Variable Documentation

char const einhard::VERSION[]

Version string of the Einhard library.
