com.hautelook.android.lib.logger;
/**
* @authorjimmy@hautelook.com
* @copyright 2011 HauteLook
*
* Description:
* Simple logger that displays: class name, method name and line number
*
*
* Usage:
*
* Use this class directly or customize it by extending it.
*
* HLlog.i("");
* HLLog.i("called");
* HLLog.i("called","tag");
*
* L.i();
* L.i("called");
* L.i("called","tag");
*
* Sub-classing example:
*
* // C.DEBUG = boolean true/false (project specific constant class)
*
* public class L extends HLLog {
*
* public static String DEFAULT_TAG = "HauteLook";
*
* public static void i() {
* if(C.DEBUG) callLogger("i", DEFAULT_TAG, "");
* }
*
* public static void i(String message) {
* if(C.DEBUG) callLogger("i", DEFAULT_TAG, message);
* }
*
* public static void i(String message, String tag) {
* if(C.DEBUG) callLogger("i", tag, message);
* }
*
* }
