Detailed Description

A conversion pattern for message templates.

ealogger supports several conversion patterns that let you substitude a pattern within a string with an appropriate value. This way the style of the log messages can be set for each log sink. Currently we support these conversion patterns

d : Date Time as provided f : Name of the file from where a log message was issued F : Absolut path of a file as provided by FILE from where a log message was issued l : Line number of the file from where a log message was issued (LINE) u : Name of the function from where a log message was issued (func) h : Hostname t : Thread ID m : Log message s : Log level / severity

Constructor & Destructor Documentation

ealogger::ConversionPattern::ConversionPattern ( std::string  conv_pattern, const PATTERN_TYPE  ptype  )

inline

Constructor for the a conversion pattern.

Parameters

conv_pattern	The conversion pattern
ptype	conversion pattern identifier

Member Function Documentation

ConversionPattern::PATTERN_TYPE ealogger::ConversionPattern::get_pattern_type ( ) const

inline

Get the conversion pattern type.

Returns

Conversion pattern identifier

template<typename T >

void ealogger::ConversionPattern::replace_conversion_pattern ( std::string &  msg, T  new_value  ) const

inline

Replace conversion pattern with new_value.

Parameters

msg	Message template reference
new_value	Value to replace all occurences of the conversion pattern with

template<>

void ealogger::ConversionPattern::replace_conversion_pattern ( std::string &  msg, std::string  new_value  ) const

inline

Replace conversion pattern with new_value.

Parameters

msg	The message pattern
new_value	New value

This method is a specialization of ConversionPattern::replace_conversion_pattern(std::string, T) Here the actual replacement of all occurences of the conversion pattern with a dedicated value takes place.
