ts-collection/lib/util/collection.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 isCollection(param) {
    if (param === undefined || param === null) {
        return false;
    }
    return param.size !== undefined
        && param.isEmpty !== undefined
        && param.contains !== undefined
        && param.iterator !== undefined
        && param.toArray !== undefined
        && param.add !== undefined
        && param.remove !== undefined
        && param.containsAll !== undefined
        && param.addAll !== undefined
        && param.removeAll !== undefined
        && param.retainAll !== undefined
        && param.clear !== undefined;
}
exports.isCollection = isCollection;
