Class JSToIntegerAsLongNode

java.lang.Object

com.oracle.truffle.api.nodes.Node

com.oracle.truffle.js.nodes.JavaScriptBaseNode

com.oracle.truffle.js.nodes.cast.JSToIntegerAsLongNode

All Implemented Interfaces:

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

public abstract class JSToIntegerAsLongNode
extends JavaScriptBaseNode

Basically ECMAScript ToInteger, but correct only for values in the safe integer range. Used by built-in functions that do not care about values outside this range, such as array length or array index conversion. Returns long; values that do not fit into long will be clamped to Long.MAX_VALUE or Long.MIN_VALUE.
