| <div class="block"><p>SharedClassHelperFactory provides an interface that is |
| used to create various types of SharedClassHelper for ClassLoaders.</p> |
| |
| <p>ClassLoaders and SharedClassHelpers have a one-to-one relationship. |
| Any attempts to get a helper for a ClassLoader that already has a different type of helper |
| will result in a HelperAlreadyDefinedException.</p> |
| |
| There are 3 different types of SharedClassHelper:<br> |
| <ol> |
| <li>SharedClassTokenHelper<br> |
| Stores and finds classes using a String token generated by the ClassLoader. |
| For use by ClassLoaders that require complete control over cache contents.</li> |
| |
| <li>SharedClassURLHelper<br> |
| Stores and finds classes using a URL location. Any URL can be used to store or find classes.<br> |
| For use by ClassLoaders that do not have the concept of a classpath, which load classes from multiple locations.<br> |
| Classes can only be stored using jar/zip or file URLs. Classes are automatically kept up-to-date by the cache.<br> |
| Classes stored using SharedClassURLClasspathHelper can be found by using this helper, and vice versa.</li> |
| |
| <li>SharedClassURLClasspathHelper<br> |
| Stores and finds classes using a URL classpath. URLs can be appended to the classpath at any time. |
| The classpath can also be modified under certain circumstances (see SharedClassURLClasspathHelper javadoc).<br> |
| For use by ClassLoaders that load classes by using a URL classpath.<br> |
| Classes can only be stored using jar/zip or file URLs. Classes are automatically kept up-to-date by the cache.<br> |
| Classes stored using SharedClassURLHelper can be found using this helper, and vice versa.</li> |
