Class JSProperty

java.lang.Object
com.oracle.truffle.js.runtime.objects.JSProperty
public final class JSProperty extends Object
Property objects represent the mapping between low-level stores and high-level data. The simplest Property could be nothing more than a map of one index to one property's value, but abstracting the interface allows for getter/setter methods, type-checked properties, and other such specialized and language-specific behavior.
