public class RuntimeVisibleParameterAnnotations
extends Attribute

The RuntimeVisibleParameterAnnotations attribute is a variable length attribute in the attributes table of the method_info structure. The RuntimeVisibleParameterAnnotations attribute records runtime-visible Java programming language annotations on the parameters of the corresponding method. Each method_info structure may contain at most one RuntimeVisibleParameterAnnotations attribute, which records all the runtime-visible Java programming language annotations on the parameters of the corresponding method. The JVM must make these annotations available so they can be returned by the appropriate reflective APIs.

The RuntimeVisibleParameterAnnotations attribute has the following format:

   RuntimeVisibleParameterAnnotations_attribute {
     u2 attribute_name_index;
     u4 attribute_length;
     u1 num_parameters;
     {
       u2 num_annotations;
       annotation annotations[num_annotations];
     } parameter_annotations[num_parameters];
   }
 
 The items of the RuntimeVisibleParameterAnnotations structure are as follows:
 

 
attribute_name_index
 
The value of the attribute_name_index item must be a valid index into the
     constant_pool table. The constant_pool entry at that index must be a
     CONSTANT_Utf8_info structure representing the string
     "RuntimeVisibleParameterAnnotations".
 
attribute_length
 
The value of the attribute_length item indicates the length of the attribute,
     excluding the initial six bytes. The value of the attribute_length item is
     thus dependent on the number of parameters, the number of runtime-visible
     annotations on each parameter, and their values.
 
num_parameters
 
The value of the num_parameters item gives the number of parameters of the
     method represented by the method_info structure on which the annotation
     occurs. (This duplicates information that could be extracted from the method
     descriptor.)
 
parameter_annotations
 
Each value of the parameter_annotations table represents all of the
     runtime-visible annotations on a single parameter. The sequence of values in
     the table corresponds to the sequence of parameters in the method signature.
     Each parameter_annotations entry contains the following two items:
     

     
num_annotations
     
The value of the num_annotations item indicates the number of runtime-visible
         annotations on the parameter corresponding to the sequence number of this
         parameter_annotations element.
     
annotations
     
Each value of the annotations table represents a single runtime-visible
         annotation on the parameter
         corresponding to the sequence number of this parameter_annotations element.
