9 years ago Well I extended the API slightly, but providing APIs like "getParameterIntValue" is a tricky thing because the members can be of arbitrary classes (JAnnotationArrayMember, JAnnotationStringValue or JAnnotationUse itself). Instead I provided a generic "getParam" returning AbstractJAnnotationValue, a "getConstantParam" returning only JAnnotationStringValue and finally "getConstantParamValue" returning the value expression inside the JAnnotationStringValue. Now if accessors for primitives are required there are imho 2 options: 1. provide a default value in the method (like 'int getParamIntValue (String name, int defaultValue)') or 2. return the primitive wrapper type (like 'Integer getParamIntValue (String name)') which can therefore be null.
I personally think the second alternative looks nicer.

Annotation parameters are compile-time values. It would be convinient to access them all the way through code generation. AnnotationUse class should be extended to provide access to parameter values
Add
method or add collection of methods corresponding to AnnotationUse.param methods:
int getParameterIntValue(String parameterName); long getParameterLongValue(String parameterName); ... int[] getParameterIntArrayValue(String parameterName); long[] getParameterLongArrayValue(String parameterName); ... String getParameterStringValue(String parameterName); Annotation getParameterAnnotationValue(String parameterName); Class<?> getParameterClassValue(String parameterName); Enum<?> getParameterEnumValue(String parameterName); ... String[] getParameterStringArrayValue(String parameterName); ...
