Class JSPrepareThisNode

java.lang.Object

com.oracle.truffle.api.nodes.Node

com.oracle.truffle.js.nodes.JavaScriptBaseNode

com.oracle.truffle.js.nodes.JavaScriptNode

com.oracle.truffle.js.nodes.unary.JSUnaryNode

com.oracle.truffle.js.nodes.cast.JSPrepareThisNode

All Implemented Interfaces:

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

public abstract class JSPrepareThisNode
extends JSUnaryNode

Implementation of the implicit this argument conversion upon entering non-strict functions (OrdinaryCallBindThis). Converts the caller provided thisArg to the ThisBinding of the callee's execution context, replacing null or undefined with the global object and performing ToObject on primitives.
