The Seam Remoting framework provides simple map support where no native support is available in JavaScript. To create a map that can be used as a parameter to a remote call, create a new Seam.Remoting.Map object:

var map = new Seam.Remoting.Map();

This JavaScript implementation provides basic methods for working with Maps: size(), isEmpty(), keySet(), values(), get(key), put(key, value), remove(key) and contains(key). Each of these methods is equivalent to the Java method of the same name. Where the method returns a collection, as in keySet() and values(), a JavaScript array object will be returned that contains the key or value objects (respectively).
