901
* Setting up the provider:
902
* <pre><code>
903
* var socket = new easyXDM.Socket({
904
* &nbsp; local: "name.html",
905
* &nbsp; onReady: function(){
906
* &nbsp; &nbsp; &#47;&#47; you need to wait for the onReady callback before using the socket
907
* &nbsp; &nbsp; socket.postMessage("foo-message");
908
* &nbsp; },
909
* &nbsp; onMessage: function(message, origin) {
910
* &nbsp;&nbsp; alert("received " + message + " from " + origin);
911
* &nbsp; }
912
* });
913
* </code></pre>
914
* Setting up the consumer:
915
* <pre><code>
916
* var socket = new easyXDM.Socket({
917
* &nbsp; remote: "http:&#47;&#47;remotedomain/page.html",
918
* &nbsp; remoteHelper: "http:&#47;&#47;remotedomain/name.html",
919
* &nbsp; onReady: function(){
920
* &nbsp; &nbsp; &#47;&#47; you need to wait for the onReady callback before using the socket
921
* &nbsp; &nbsp; socket.postMessage("foo-message");
922
* &nbsp; },
923

924
* &nbsp;&nbsp; alert("received " + message + " from " + origin);
925
* &nbsp; }
926
* });
927
* </code></pre>
928
* If you are unable to upload the <code>name.html</code> file to the consumers domain then remove the <code>remoteHelper</code> property
929
* and easyXDM will fall back to using the HashTransport instead of the NameTransport when not able to use any of the primary transports.
930
* @namespace easyXDM
931
* @constructor
932
* @cfg {String/Window} local The url to the local name.html document, a local static file, or a reference to the local window.
933
* @cfg {Boolean} lazy (Consumer only) Set this to true if you want easyXDM to defer creating the transport until really needed.
934
* @cfg {String} remote (Consumer only) The url to the providers document.
935
* @cfg {String} remoteHelper (Consumer only) The url to the remote name.html file. This is to support NameTransport as a fallback. Optional.
936
* @cfg {Number} delay The number of milliseconds easyXDM should try to get a reference to the local window. Optional, defaults to 2000.
937
* @cfg {Number} interval The interval used when polling for messages. Optional, defaults to 300.
938
* @cfg {String} channel (Consumer only) The name of the channel to use. Can be used to set consistent iframe names. Must be unique. Optional.
939
* @cfg {Function} onMessage The method that should handle incoming messages.<br/> This method should accept two arguments, the message as a string, and the origin as a string. Optional.
940
* @cfg {Function} onReady A method that should be called when the transport is ready. Optional.
941
* @cfg {DOMElement|String} container (Consumer only) The element, or the id of the element that the primary iframe should be inserted into. If not set then the iframe will be positioned off-screen. Optional.
942
* @cfg {Array/String} acl (Provider only) Here you can specify which '[protocol]://[domain]' patterns that should be allowed to act as the consumer towards this provider.<br/>
943
* This can contain the wildcards ? and *. Examples are 'http://example.com', '*.foo.com' and '*dom?.com'. If you want to use reqular expressions then you pattern needs to start with ^ and end with $.
944
* If none of the patterns match an Error will be thrown.
945
* @cfg {Object} props (Consumer only) Additional properties that should be applied to the iframe. This can also contain nested objects e.g: <code>{style:{width:"100px", height:"100px"}}</code>.
946
* Properties such as 'name' and 'src' will be overrided. Optional.

1000

* <h2>Exposing functions (procedures)</h2>
1002
* <pre><code>
1003
* var rpc = new easyXDM.Rpc({
1004
* &nbsp; ...
1005
* },{
1006
* &nbsp; local: {
1007

1008
* &nbsp; &nbsp; &nbsp; method: function(arg1, arg2, success, error){

* &nbsp; &nbsp; &nbsp; &nbsp; ...
1010
* &nbsp; &nbsp; &nbsp; }
1011
* &nbsp; &nbsp; },
1012
* &nbsp; &nbsp; &#47;&#47; with shorthand notation
1013
* &nbsp; &nbsp; nameOfAnotherMethod: function(arg1, arg2, success, error){
1014
* &nbsp; &nbsp; }
1015
* &nbsp; },
1016
* &nbsp; remote: {...}
1017
* });
1018
* </code></pre>
1019
* The function referenced by [method] will receive the passed arguments followed by the callback functions <code>success</code> and <code>error</code>.<br/>
1020
* To send a successfull result back you can use
1021
* <pre><code>
1022
* return foo;
1023
* </pre></code>
1024
* or
1025
* <pre><code>
1026
* success(foo);
1027
* </pre></code>
1028
* To return an error you can use
1029
* <pre><code>
1030
* throw new Error("foo error");
1031
* </code></pre>
1032
* or
1033
* <pre><code>
1034
* error("foo error");
1035
* </code></pre>
1036
*
1037
* <h2>Defining remotely exposed methods (procedures/notifications)</h2>
1038
* The definition of the remote end is quite similar:
1039
* <pre><code>
1040
* var rpc = new easyXDM.Rpc({
1041
* &nbsp; ...
1042
* },{
1043
* &nbsp; local: {...},
1044
* &nbsp; remote: {
1045
* &nbsp; &nbsp; nameOfMethod: {}
1046
* &nbsp; }
1047
* });
1048
* </code></pre>
1049
* To call a remote method use
1050
* <pre><code>
1051
* rpc.nameOfMethod("arg1", "arg2", function(value) {
1052
* &nbsp; alert("success: " + value);
1053
* }, function(message) {
1054
* &nbsp; alert("error: " + message + );
1055
* });
1056
* </code></pre>
1057
* Both the <code>success</code> and <code>errror</code> callbacks are optional.<br/>
1058
* When called with no callback a JSON-RPC 2.0 notification will be executed.
1059
* Be aware that you will not be notified of any errors with this method.
1060
* <br/>
1061
* <h2>Specifying a custom serializer</h2>
1062
* If you do not want to use the JSON2 library for non-native JSON support, but instead capabilities provided by some other library
1063
* then you can specify a custom serializer using <code>serializer: foo</code>
1064
* <pre><code>
1065
* var rpc = new easyXDM.Rpc({
1066
* &nbsp; ...
1067
* },{
1068
* &nbsp; local: {...},
1069
* &nbsp; remote: {...},
1070
* &nbsp; serializer : {
1071
* &nbsp; &nbsp; parse: function(string){ ... },
1072
* &nbsp; &nbsp; stringify: function(object) {...}
1073
* &nbsp; }
1074
* });
1075
* </code></pre>
1076
* If <code>serializer</code> is set then the class will not attempt to use the native implementation.
1077
* @namespace easyXDM
1078
* @constructor
1079
* @param {Object} config The underlying transports configuration. See easyXDM.Socket for available parameters.
