# Interface InvokeDynamicInstruction

All Superinterfaces:
  `ClassFileElementPREVIEW`, `CodeElementPREVIEW`, `InstructionPREVIEW`

public sealed interface InvokeDynamicInstruction extends InstructionPREVIEW
`InvokeDynamicInstruction` is a preview API of the Java platform.
Programs can only use `InvokeDynamicInstruction` when preview features are enabled.
Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.
Models an `invokedynamic` instruction in the `code` array of a `Code` attribute. Delivered as a `CodeElement`PREVIEW when traversing the elements of a `CodeModel`PREVIEW.
