-/**
- * The class `Instrumentation` implements support for logging instrumentation information.
- *
- * Instrumentation information consists of information about specific operations. Those operations
- * can range from user-facing operations, such as saving the changes to a file, to internal
- * operations, such as tokenizing source code. The information to be logged is gathered by
- * [InstrumentationBuilder], created by one of the static methods on
- * this class such as [builder] or [builder].
- *
- * Note, however, that until an instrumentation logger is installed using the method
- * [setLogger], all instrumentation data will be lost.
- *
- * <b>Example</b>
- *
- * To collect metrics about how long it took to save a file, you would write something like the
- * following:
- *
- * <pre>
- * InstrumentationBuilder instrumentation = Instrumentation.builder(this.getClass());
- * // save the file
- * instrumentation.metric("chars", fileLength).log();
- * </pre>
- * The `Instrumentation.builder` method creates a new [InstrumentationBuilder]
- * and records the time at which it was created. The
- * [InstrumentationBuilder.metric] appends the information specified by the
- * arguments and records the time at which the method is called so that the time to complete the
- * save operation can be calculated. The `log` method tells the builder that all of the data
- * has been collected and that the resulting information should be logged.
