|
|
|
7 * Logger - a very simple logger, mainly used during development.
|
|
|
8 * Is not based on log4j (to reduce external dependencies).
|
|
|
9 * However, if needed, something like log4j could easily be
|
|
|
10 * hooked in.
|
|
|
11 * <p>
|
|
|
12 * For speed reasons, the static variables are not protected
|
|
|
13 * with semaphores. In other words, if you dynamicaly change the
|
|
|
14 * logging settings, then some threads may still use the old setting.
