- Drop 'expectedType' parameter from #getClass and #getEnum methods and
rely on compiler inference based on type of assigned variable, e.g.
public @interface Example {
Color color();
Class<? extends UserType> userType();
int order() default 0;
}
AnnotationAttributes example =
AnnotationUtils.getAnnotationAttributes(Example.class, true, true);
Color color = example.getEnum("color");
Class<? extends UserType> userType = example.getClass("userType");
or in cases where there is no variable assignment (and thus no
inference possible), use explicit generic type, e.g.
bean.setColor(example.<Color>getEnum("color"));
- Rename #get{Int=>Number} and update return type from int to
<N extends Number>, allowing invocations such as:
int order = example.getNumber("order");
These changes reduce the overall number of methods exposed by
AnnotationAttributes, while at the same time providing comprehensive
access to all possible annotation attribute types -- that is, instead of
requiring explicit #getInt, #getFloat, #getDouble methods, the
single #getNumber method is capabable of handling them all, and without
any casting required. And the obvious additional benefit is more concise
invocation as no redundant 'expectedType' parameters are required.
Spring Framework
The Spring Framework provides a comprehensive programming and configuration model for modern Java-based enterprise applications - on any kind of deployment platform. A key element of Spring is infrastructural support at the application level: Spring focuses on the "plumbing" of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments.
The framework also serves as the foundation for Spring Integration, Spring Batch and the rest of the Spring family of projects. Browse the repositories under the SpringSource organization on GitHub for a full list.
.NET and Python variants are available as well.
