+/**
+ * <p>A <code>Log</code> object is used by RI classes to log messages.
+ * They will be logged in any environment that has setup a logging service
+ * such as Log4J or the standard JDK logging facilities. In fact, this
+ * logging interface is very similar to the other facilities with the
+ * difference that logging methods also take any number of optional
+ * parameters beyond the message object for later interpolation
+ * into the message.</p>
+ *
+ * <p>The idea of using interpolation parameters is very important for
+ * performance reasons in production code. Normally developers write
+ * logging messages similar to this one:
+ * <pre>
+ * log.debug("Started processing of " + obj1 + " with action " + obj2);
+ * </pre>
+ * The problem that arises at runtime in production systems, is that DEBUG
+ * level logging may not be enabled. And even if this logging is going to
+ * be a no-op call, Java must still build the string dynamically that is the
+ * argument to the call. It is the building of this string that can be quite
+ * time consuming. The more complex the objects being concatenated are, the
+ * worse the time penalty incurred is. And this time is completely wasted
+ * since the string may never be used.</p>
+ *
+ * <p>Normally to combat the problem of making this call and building the
+ * string dynamically, the developer uses a conditional statement to invoke
+ * the call only if the corresponding logging level is enabled. So the above
+ * call may end up looking like:
+ * <pre>
+ * if (log.isDebugEnabled())
+ * {
+ * log.debug("Started processing of " + obj1 + " with action " + obj2);
+ * }
+ * </pre>
+ * Ideally, this structure should always be used to avoid the cost of building the
+ * dynamic string (concatenation) and making the unnecessary call. The only
+ * drawback to this is that code can become less readable. In some cases, there
+ * might be more code devoted to logging than the actual behavior required by a
+ * method.</p>
+ *
+ * <p>A cleaner way to do the logging is to use this interface where simple
+ * objects without any concatenation are passed as arguments. Albeit the call
+ * itself may still be a no-op when the logging level is not enabled, this is
+ * still much smaller than the concatenation process with dynamic strings. Each
+ * of the methods defined here will first check to see if the logging level is enabled,
+ * if that feature exists in the underlying logging system. If and only if that logging
+ * level is enabled, will the implementation proceed with concatenation of the strings
+ * and objects passed. So the above code using this interface becomes:
+ * <pre>
+ * log.debug("Started processing of {0} with action {1}, obj1, obj2);
+ * </pre>
+ * </p>
+ *
+ * <p>The interpolation of parameters into the message string are done using
+ * {@link java.text.MessageFormat}. See the documentation on that class for
+ * more ideas of interpolation possibilities. In the above code, <code>obj1</code>
+ * and <code>obj2</code> simply have their <code>toString()</code> methods invoked
+ * to produce a string which is then concatenated.</p>
