Class OperatorSet

java.lang.Object

com.oracle.truffle.js.runtime.objects.OperatorSet

public class OperatorSet
extends Object

Instances of this class represent instances of the OperatorSet spec object. These hold the definitions of any overloaded operators for a given type. Each such OperatorSet has a unique numerical ID (OperatorSet.getOperatorCounter()), which are used for dispatching overloaded operators between different classes (e.g. Matrix * Vector). An instance of this class is held in an internal slot by the constructor of the class that overloads operators. This instance is then also reachable from an internal slot of every instance of that class (we use a constant property that is bound to the objects' Shape).
