public interface DeoptimizingNode
extends NodeWithState

Interface implemented by nodes which may need deoptimization information.

Sub-interfaces are used to specify exactly when the deoptimization can take place: before, after, and/or during.
Note that these sub-interfaces are not mutually exclusive so that nodes that may deoptimize at multiple times can be modeled.
