Interface ModuleTargetAttribute

All Superinterfaces:
Attribute<ModuleTargetAttribute>, ClassElement, ClassFileElement
public sealed interface ModuleTargetAttribute extends Attribute<ModuleTargetAttribute>, ClassElement
Models the ModuleTarget attribute, which can appear on classes that represent module descriptors, to represent constraints on the target platform.

The specification of the ModuleTarget attribute is:

TargetPlatform_attribute {
  // index to CONSTANT_utf8_info structure in constant pool representing
  // the string "ModuleTarget"
  u2 attribute_name_index;
  u4 attribute_length;

  // index to CONSTANT_utf8_info structure with the target platform
  u2 target_platform_index;
}
 

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.
