trace("Method "+name+" was called");
};
// define the __resolve function
myObject.__resolve = function(name) {
// reserve the name “onStatus” for local use
if (name == "onStatus") {
return undefined;
}
trace("Resolve called for "+name); // to check when __resolve is called
// Not only call the function, but also save a reference to it
var f:Function = function () {
this.myFunction(name);
};
// create a new object method and assign it the reference
this[name] = f;
// return the reference
return f;
};
// test __resolve using the method name "onStatus"
trace(myObject.onStatus("hello"));
// output: undefined
Usage 5: The following example builds on the previous example by creating a functor that accepts
parameters. This example makes extensive use of the
arguments object , and uses several methods
of the Array class .
// instantiate a new object
var myObject:Object = new Object();
// define a generic function for __resolve to call
myObject.myFunction = function (name) {
arguments.shift();
trace("Method " + name + " was called with arguments: " +
arguments.join(',')) ;
};
// define the __resolve function
myObject.__resolve = function (name) {
// reserve the name “onStatus” for local use
if (name == "onStatus") {
return undefined;
}
var f:Function = function () {
arguments.unshift(name);
this.myFunction.apply(this, arguments);
};
// create a new object method and assign it the reference
this[name] = f;
// return the reference to the function
return f;
};
// test __resolve using undefined method names with parameters
myObject.someMethod("hello");
// output: Method someMethod was called with arguments: hello
