Field Summary

static Level	ALL           The ALL has the lowest possible rank and is intended to turn on all logging.
static Level	DEBUG           The DEBUG Level designates fine-grained informational events that are most useful to debug an application.
static Level	ERROR           The ERROR level designates error events that might still allow the application to continue running.
static Level	FATAL           The FATAL level designates very severe error events that will presumably lead the application to abort.
static Level	INFO           The INFO level designates informational messages that highlight the progress of the application at coarse-grained level.
static Level	OFF           The OFF has the highest possible rank and is intended to turn off logging.
static Level	TRACE           The TRACE Level designates finer-grained informational events than the DEBUG
static int	TRACE_INT           TRACE level integer value.
static Level	WARN           The WARN level designates potentially harmful situations.
