Array where you can add methods which will be called on each entry.

DelegateCollection.js

//==============================================================================
function DelegateCollection() {
  for (var i = 0, m = arguments.length; i < m; i++) {
    this.addCall(arguments[i]);
  }
}

//------------------------------------------------------------------------------
DelegateCollection.prototype = new Array;

DelegateCollection.prototype.addCall = function(name) {
  this[name] = function() {
    var args = arguments;
    this.forEach(function(item) {
      try {
        item[name].apply(item, args);
      }
      catch(e) {
        console.error('DelegateCollection::' + name);
        console.error(e);
      }
    });
    return this;
  };
};
