All Implemented Interfaces:

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

Enclosing class:

PropertyCacheNode<T extends PropertyCacheNode.CacheNode<T>>

protected static final class PropertyCacheNode.TraversePrototypeChainShapeCheckNode
extends PropertyCacheNode.AbstractShapeCheckNode

Check the shapes of the prototype chain up to the given depth. This class actually traverses the prototype chain and checks each prototype shape's identity.
