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.
