A log library that embraces the kiss principle.

There is a newer version: 2.1.2

package org.mentalog.util;

import org.mentalog.Log;

/**
 * This code is NOT thread-safe at all.
 * 
 * You can use to_sb to bypass autoboxing and avoid the object creation. So intead of:
 * 
 * Info.log(myInteger);
 * 
 * you would do:
 * 
 * Info.log(to_sb(myInteger));
 * 
 * NOTE: If you want to use this from multiple threads you MUST synchronize around to_sb:
 * 
 * synchronized(Info) { Info.log(to_sb(myInteger)); }
 *
