All Implemented Interfaces:

com.oracle.truffle.api.instrumentation.InstrumentableNode, com.oracle.truffle.api.nodes.NodeInterface, Cloneable

public abstract class IteratorGetNextValueNode
extends JavaScriptNode

Combines IteratorStep and IteratorValue in one node. Equivalent to the following steps:

1. Let next be IteratorStep(iteratorRecord).
2. (opt) If next is an abrupt completion, set iteratorRecord.[[Done]] to true.
3. ReturnIfAbrupt(next).
4. If next is false,
   1. (opt) Set iteratorRecord.[[Done]] to true.
   2. Return doneResult.
5. Else,
   1. Let value be IteratorValue(next).
   2. (opt) If value is an abrupt completion, set iteratorRecord.[[Done]] to true.
   3. Return value.
