RuntimeInvisibleParameterAnnotationspublic 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
{@link Annotation annotation} on the parameter corresponding to the sequence
number of this parameter_annotations element.
