rx-postmessenger/esm/MessageIDGenerator.js

Minimal RxJS adapter for the window.postMessage API for request-response streams and notification streams across frame windows.

import { GUIDGenerator } from './functions/GUIDGenerator';
var MessageIDGenerator = /** @class */ (function () {
    function MessageIDGenerator(gen) {
        if (gen === void 0) { gen = GUIDGenerator(); }
        this.gen = gen;
        this.usedIDValues = [];
    }
    MessageIDGenerator.prototype.generateID = function () {
        var newID;
        do {
            newID = this.gen.next().value;
        } while (this.usedIDValues.indexOf(newID) >= 0);
        this.invalidateID(newID);
        return newID;
    };
    MessageIDGenerator.prototype.invalidateID = function (id) {
        this.usedIDValues.push(id);
    };
    return MessageIDGenerator;
}());
export { MessageIDGenerator };
