logging-annotation

Simple active annotation for Xtend, which automaticly generate helper methods for logging for various frameworks. Currently it is possible to switch between using

• java.util.logging
• slf4j (logback)
• plain log4j

Usage:

@Logging(type="Slf4J")
class Slf4jTest {
	def method() {
		info [|"hello world!"]
		debug [|"logging "]		
	}	
}

or

@Logging(type="JavaUtilLogging")
class JULTest {
    def method() {
        info [|"hello world!"]
        debug [|"logging "]		
    }	
}

or

@Logging(type="Log4J")
class Log4jTest {
    def method() {
        info [|"hello world!"]
        debug [|"logging "]		
    }	
}

where the info and debug methods take a lambda method, which only called, if the actual logging level is enabled. Unfortunately, due for a bug, the 'type' in the annotation must be a string, and can't be an enumeration.
