ASMRuntimeInvisibleParameterAnnotations

public class RuntimeInvisibleParameterAnnotations

extends Attribute

The RuntimeInvisibleParameterAnnotations attribute is similar to the RuntimeVisibleParameterAnnotations attribute, except that the annotations represented by a RuntimeInvisibleParameterAnnotations attribute must not be made available for return by reflective APIs, unless the JVM has specifically been instructed to retain these annotations via some implementation-specific mechanism such as a command line flag. In the absence of such instructions, the JVM ignores this attribute.

The RuntimeInvisibleParameterAnnotations attribute is a variable length attribute in the attributes table of the method_info structure. The RuntimeInvisibleParameterAnnotations attribute records runtime-invisible Java programming language annotations on the parameters of the corresponding method. Each method_info structure may contain at most one RuntimeInvisibleParameterAnnotations attribute, which records all the runtime-invisible Java programming language annotations on the parameters of the corresponding method.

The RuntimeInvisibleParameterAnnotations attribute has the following format:

   RuntimeInvisibleParameterAnnotations_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 RuntimeInvisibleParameterAnnotations 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 "RuntimeInvisibleParameterAnnotations".

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-invisible 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-invisible 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-invisible 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-invisible annotation on the parameter corresponding to the sequence number of this parameter_annotations element.
