ts-collection/lib/util/comparator.js

This is re-write of the java collection classes in typescript. There is some tweak as typescript templates are not as equivalent as Java.

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
function isComparator(param) {
    if (param === undefined || param === null) {
        return false;
    }
    return param.compare !== undefined;
}
exports.isComparator = isComparator;
