Class EnclosingMethodAttribute

public class EnclosingMethodAttribute extends Attribute

The EnclosingMethod attribute is an optional fixed-length attribute in the attributes table of the ClassFile structure. A class must have an EnclosingMethod attribute if and only if it is a local class or an anonymous class. A class may have no more than one EnclosingMethod attribute. The EnclosingMethod attribute has the following format:
   EnclosingMethod_attribute {
     u2 attribute_name_index;
     u4 attribute_length;
     u2 class_index
     u2 method_index;
   }
 
The items of the EnclosingMethod_attribute 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 "EnclosingMethod".
attribute_length
The value of the attribute_length item is four.
class_index
The value of the class_index item must be a valid index into the constant_pool table. The constant_pool entry at that index must be a CONSTANT_Class_info structure representing the innermost class that encloses the declaration of the current class.
method_index
If the current class is not immediately enclosed by a method or constructor, then the value of the method_index item must be zero. Otherwise, the value of the method_index item must be a valid index into the constant_pool table. The constant_pool entry at that index must be a CONSTANT_NameAndType_info structure representing a the name and type of a method in the class referenced by the class_index attribute above. It is the responsibility of the Java compiler to ensure that the method identified via the method_index is indeed the closest lexically enclosing method of the class that contains this EnclosingMethod attribute.
