Detailed Description

Provides classes & macros for easy tracing.

Author:

Version:

1.1.0

Include lobtracestream to your program will allow you to set runtime configurable traces with only 5 macros (2 mandatory + 3 optional).

the main features are:

• specify your modules, and assign a trace level for each module
• change trace levels in a config file (no need to compile to change trace levels)
• trace to output files (or standard output)
• exception and assertion handling
• multi-thread capabilities
• pure C++ (should work on all platforms), tested on Linux, SunOS, AIX
• text or XML output format
• ...

code example:

    LOB_TRACE(MODULE_SQL, WARNING) << "Unexpected value for i : " << i << lt_endl;

output will be (if MODULE_SQL trace level <= WARNING, else no trace generated):

    3-jul-2002 09:59:33   WARNING   MODULE_SQL: "Unexpected value for i : -12" [./example1.cpp:18]

Note:

ENVIRONMENT: Linux / UNIX / Windows
