\brief Class creaMessageManager and Macros for outputing messages in crea
-
There are 4 kinds of messages :
- Messages (normal messages)
- Debug messages (not compiled in release)
-The first string is the type of the message (the category which will be used to generate a message of this type)
-The second string is help string
-The integer is the initial level for the messages of this type (see below).
-
To generate a message of a known type then use one of the macros :
creaMessage, creaDebugMessage, creaWarning, creaError or their variants.
-
example :
-
creaMessage("Kernel",4,"problem with "<<GetName()<<creaendl);
-
will push the 3rd argument in std::cout if the message level of "Kernel" messages is greater or equal to 4.
which means that it generates a message of level 4 (0 : very important/always displayed ... 9 : deep debug message).
-
At run time, one is able to change the level of the messages displayed by using a command like :
-
crea::MessageManager::SetMessageLevel("Kernel",5);
-
which tells the manager to display all Kernel messages of level up to 5.
-
Variants :
-
crea*Cont : continues a previous creaMessage on the same line (without rewriting the type and level)
crea*Inc / Dec : displays the message and then increments/decrement the messages tabulation
-
