public class SourceDebugExtensionAttribute
extends Attribute

The SourceDebugExtension attribute is an optional attribute defined in JSR-045 in the attributes table of the ClassFile structure. There can be no more than one SourceDebugExtension attribute in the attributes table of a given ClassFile structure. The SourceDebugExtension attribute has the following format:

   SourceDebugExtension_attribute {
     u2 attribute_name_index;
     u4 attribute_length;
     u1 debug_extension[attribute_length];
   }
 

The items of the SourceDebugExtension_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 "SourceDebugExtension".

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 the number of bytes in the debug_extension[] item.

debug_extension[]

The debug_extension array holds a string, which must be in UTF-8 format. There is no terminating zero byte. The string in the debug_extension item will be interpreted as extended debugging information. The content of this string has no semantic effect on the Java Virtual Machine.
