36 | * <p> | |
37 | * Indicates that the marked method should be called when a field on an attached | |
38 | * object is modified. | |
39 | * | |
40 | * <p> | |
41 | * The method can have any name, but should take a single parameter which is | |
42 | * either a {@link FieldModifiedEvent} or any superclass. Otherwise, an | |
43 | * {@link IllegalArgumentException} will be thrown by | |
44 | * {@link PojoCache#addListener(java.lang.Object)} | |
45 | * | |
46 | * <p> | |
47 | * Example: | |
48 | * | |
49 | * <pre> | |
50 | * @PojoCacheListener | |
51 | * public class MyListener() | |
52 | * { | |
53 | * @FieldModified | |
54 | * public void handleModified(FieldModifiedEvent event) | |
55 | * { | |
56 | * System.out.println("Object = " + even.getSource()); | |
57 | * } | |
58 | * } | |
59 | * </pre> | |
