Detailed Description

Message object.

This object are meant to be short-lived; likely to be temporaries. You construct the message, chain some calls to operator() and then the destructor outputs an eol.

utl::MessageLogger::Message::~Message ( )

On destruction line termination is appended.

Member Function Documentation

utl::MessageLogger::Message::operator bool ( ) const

inlineexplicit

Conversion to bool is always false.

Given that false is always returned, a final message can be generated in loops with a || condition: ie the real condition used as left operand and the message a right, given short-cut evaluation the right side will be only evaluated in the last iteration.

Definition at line 106 of file MessageLogger.h.

template<typename T >

Message& utl::MessageLogger::Message::operator() ( const T &  t )

inline

Append a value separated from previous values.

Returns

A self-reference to allow chaining.
