Chris Beams e25f1cbca9 Infer AnnotationAttributes method return types - 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.	14 years ago

Chris Beams e25f1cbca9 Infer AnnotationAttributes method return types

- 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.
