Interface ModuleHashesAttribute
- All Superinterfaces:
- Attribute<ModuleHashesAttribute>,- ClassElement,- ClassFileElement
public sealed interface ModuleHashesAttribute
extends Attribute<ModuleHashesAttribute>, ClassElement
Models the 
ModuleHashes attribute, which
 appears on classes that represent
 module descriptors to capture the hashes of a set of co-delivered modules.
 
 The specification of the ModuleHashes attribute is:
 
 
 ModuleHashes_attribute {
   // index to CONSTANT_utf8_info structure in constant pool representing
   // the string "ModuleHashes"
   u2 attribute_name_index;
   u4 attribute_length;
   // index to CONSTANT_utf8_info structure with algorithm name
   u2 algorithm_index;
   // the number of entries in the hashes table
   u2 hashes_count;
   {   u2 module_name_index (index to CONSTANT_Module_info structure)
       u2 hash_length;
       u1 hash[hash_length];
   } hashes[hashes_count];
 }
  
 This attribute only appears on classes, and does not permit multiple instances in a class. It has a data dependency on the constant pool.
 This attribute is not predefined in the Java SE Platform.  This is a
 JDK-specific nonstandard attribute produced by the jdk.jlink module,
 which defines the jlink and jmod tools.
