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