| * Identifies a static method as a factory to create a plugin or a |
| * {@linkplain org.apache.logging.log4j.plugins.util.Builder builder class} for constructing a plugin. |
| * Factory methods should annotate their parameters with {@link PluginAttribute}, {@link PluginElement}, |
| * {@link PluginValue}, or other plugin annotations annotated with |
| * {@link org.apache.logging.log4j.plugins.inject.InjectorStrategy}. |
| * If a factory method returns a builder class, this method should have no arguments; instead, the builder class should |
| * annotate its fields or single-parameter methods to inject plugin configuration data. |
| * <p> |
| * There can only be one factory method per class. |
