![]() If I get the clock time and store it in a class file when the class file is compiled. You may have a really fast computer that doesn't resolve to unique times. If you really need it to be unique, you can't rely on a clock time. In the annotation definition, the name=value pairs can be specified in any does not matter", url="./help.html") topic="Order does not matter") are considered the same. The url must be specified, otherwise this will result While defining the Help annotation, the topic is optional and need not be specified.įor example, is valid. In the above example, String topic() default "Unknown Topic" declares a default The main method in Example2 illustrates how to access the annotations at runtime.ĭefault values for members can be specified in the annotation declaration so that it becomes optional It also illustrates how to define annotations with parameter values thatĪre annotations. The above example shows how to use annotations that have multiple members with String, boolean,Īnd array return types. Lic = Annotation_(License.class) // get above values getDate = (new ()).toString() // attribute value must be constant !!!! Now we can use the // These values are available for reading below ![]() That return String, boolean, and an array of Trademark annotations. ![]() In the code snippet above, we have declared an annotation called License, which has members Is my client using the same class file as I am? Comparing the id would quickly answer that. It would be used to be able easily to determine if two remotely located class files are the same. ![]() It's not important what the value in the class file is as long as it is somewhat unique. Since my posting I've found references that say that only String and int constants can be placed in annotations.ĭo you have a working code sample that would show the use of ![]()
