- 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.
