Class ContinuationRootNode

java.lang.Object

com.oracle.truffle.api.nodes.Node

com.oracle.truffle.api.nodes.ExecutableNode

com.oracle.truffle.api.nodes.RootNode

com.oracle.truffle.api.bytecode.ContinuationRootNode

All Implemented Interfaces:

NodeInterface, Cloneable

public abstract class ContinuationRootNode
extends RootNode

Abstract class representing the root node for a continuation.

These root nodes have a precise calling convention; see ContinuationResult.getContinuationCallTarget().

If a bytecode interpreter supports continuations, the Bytecode DSL will generate a concrete implementation of this interface. It should not be subclassed manually.

Since:

24.2
