* \brief Stream wrapper for log records formatting.
|
|
*
|
|
* This stream wrapper is used by the library for log record formatting. It implements the standard string stream interface
|
|
* with a few differences:
|
|
*
|
|
* \li It does not derive from standard types <tt>std::basic_ostream</tt>, <tt>std::basic_ios</tt> and <tt>std::ios_base</tt>,
|
|
* although it tries to implement their interfaces closely. There are a few small differences, mostly regarding <tt>rdbuf</tt>
|
|
* and <tt>str</tt> signatures, as well as the supported insertion operator overloads. The actual wrapped stream can be accessed
|
|
* through the <tt>stream</tt> methods.
|
|
* \li By default, \c bool values are formatted using alphabetical representation rather than numeric.
|
|
* \li The stream supports writing strings of character types different from the stream character type. The stream will perform
|
|
* character code conversion as needed using the imbued locale.
|
|
* \li The stream operates on an external string object rather than on the embedded one. The string can be attached or detached
|
|
* from the stream dynamically.
|
|
*
|
|
* Although <tt>basic_formatting_ostream</tt> does not derive from <tt>std::basic_ostream</tt>, users are not required to add
|
|
* special overloads of \c operator<< for it since the stream will by default reuse the operators for <tt>std::basic_ostream</tt>.
|
|
* However, one can define special overloads of \c operator<< for <tt>basic_formatting_ostream</tt> if a certain type needs
|
|
* special formatting when output to log.
