Interface LoadableDescriptorsAttribute

All Superinterfaces:
Attribute<LoadableDescriptorsAttributePREVIEW>, ClassElement, ClassFileElement
public sealed interface LoadableDescriptorsAttribute extends Attribute<LoadableDescriptorsAttributePREVIEW>, ClassElement
LoadableDescriptorsAttribute is a reflective preview API of the Java platform.
Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.
Models the LoadableDescriptorsPREVIEW attribute (JVMS ยง4.7.32PREVIEW), which permits the JVM to load mentioned classes and interfaces before the class file carrying this attribute is loaded.

This attribute only appears on classes, and does not permit multiple instances in a class. It has a data dependency on the constant pool.

The attribute is a preview VM feature in the current Java SE release.
