| 15 * | 14 * |
| 16 * For an example of using objects that implement this interface, see [Instrumen
tation]. | 15 * Instrumentation information consists of information about specific operations
. Those operations |
| 16 * can range from user-facing operations, such as saving the changes to a file,
to internal |
| 17 * operations, such as tokenizing source code. The information to be logged is g
athered by |
| 18 * [InstrumentationBuilder], created by one of the static methods on |

| 20 * |
| 21 * Note, however, that until an instrumentation logger is installed using the me
thod |

| 23 * |
| 24 * <b>Example</b> |
| 25 * |
| 26 * To collect metrics about how long it took to save a file, you would write som
ething like the |
| 27 * following: |
| 28 * |
| 29 * <pre> |
| 30 * InstrumentationBuilder instrumentation = Instrumentation.builder(this.getClas
s()); |
| 31 * // save the file |
| 32 * instrumentation.metric("chars", fileLength).log(); |
| 33 * </pre> |
| 34 * The `Instrumentation.builder` method creates a new [InstrumentationBuilder |
| 35 ] and records the time at which it was created. The |
| 36 * [InstrumentationBuilder#metric] appends the information specified by the |
| 37 * arguments and records the time at which the method is called so that the time
to complete the |
| 38 * save operation can be calculated. The `log` method tells the builder that all
of the data |
| 39 * has been collected and that the resulting information should be logged. |
