/** |
|
53 |
* The Introspector class provides a standard way for tools to learn about |
|
54 |
* the properties, events, and methods supported by a target Java Bean. |
|
55 |
* <p> |
|
56 |
* For each of those three kinds of information, the Introspector will |
|
57 |
* separately analyze the bean's class and superclasses looking for |
|
58 |
* either explicit or implicit information and use that information to |
|
59 |
* build a BeanInfo object that comprehensively describes the target bean. |
|
60 |
* <p> |
|
61 |
* For each class "Foo", explicit information may be available if there exists |
|
62 |
* a corresponding "FooBeanInfo" class that provides a non-null value when |
|
63 |
* queried for the information. We first look for the BeanInfo class by |
|
64 |
* taking the full package-qualified name of the target bean class and |
|
65 |
* appending "BeanInfo" to form a new class name. If this fails, then |
|
66 |
* we take the final classname component of this name, and look for that |
|
67 |
* class in each of the packages specified in the BeanInfo package search |
|
68 |
* path. |
|
69 |
* <p> |
|
70 |
* Thus for a class such as "sun.xyz.OurButton" we would first look for a |
|
71 |
* BeanInfo class called "sun.xyz.OurButtonBeanInfo" and if that failed we'd |
|
72 |
* look in each package in the BeanInfo search path for an OurButtonBeanInfo |
|
73 |
* class. With the default search path, this would mean looking for |
|
74 |
* "sun.beans.infos.OurButtonBeanInfo". |
|
75 |
* <p> |
|
76 |
* If a class provides explicit BeanInfo about itself then we add that to |
|
77 |
* the BeanInfo information we obtained from analyzing any derived classes, |
|
78 |
* but we regard the explicit information as being definitive for the current |
|
79 |
* class and its base classes, and do not proceed any further up the superclass |
|
80 |
* chain. |
|
81 |
* <p> |
|
82 |
* If we don't find explicit BeanInfo on a class, we use low-level |
|
83 |
* reflection to study the methods of the class and apply standard design |
|
84 |
* patterns to identify property accessors, event sources, or public |
|
85 |
* methods. We then proceed to analyze the class's superclass and add |
|
86 |
* in the information from it (and possibly on up the superclass chain). |
|
87 |
* <p> |
|
88 |
* For more information about introspection and design patterns, please |
|
89 |
* consult the |
