Examples of com.ecyrd.speed4j.StopWatch

com.ecyrd.speed4j.StopWatch
Creates a simple StopWatch with nanosecond precision (though not necessarily accuracy).
A "tag" is an unique grouping identifier. A "message" can be anything you like; it just travels with the StopWatch and is output with the toString method.
Tags must not contain whitespace, forward slash or commas. All other characters are allowed.
Most of the StopWatch methods return a reference to itself for easy chaining.
