Detailed Description

Basic message writing.

Support for singleton.

Two ways to use with operator << - either through operator () with ostream or cast to base (message&) - which does have template issues.

Example - with casting down and template issue

  (message&)err << x << endl<char, char_traits<char> >;

Member Function Documentation

void message::globalset

(

)

[inline]

This instance becomes the global message state.

Definition at line 40 of file message.h.

References global.

Referenced by main().

    { global = this; }

virtual ostream& message::operator()

(

)

[pure virtual]

Write to the stream.

Implemented in messagecout, messagefile, and messagelist.

template<typename T >

message& message::operator<<

(

T &

x

)

[inline]

Write with pre and post processing.

As I do not want to deal with streams pre and post put in for flexibility.

Definition at line 58 of file message.h.

References post(), and pre().

  { 
    pre(); 
    (*this)() << x; 
    post(); 
    return *this; 
  }

virtual void message::post

)

[inline, virtual]

Optionally post process before << operator.

Reimplemented in messagelist.

virtual void message::pre
