Two simple SnippetRunner questions which I cannot answer.

Question

I've started with "JavaScripting" and to be honest I am still confused. I played a little bit with SnippetRunner example.So I have two questions.
1)Where does "sdkCodeSnippetRunnerObject" name come from?
In "snippetrunner\examplefiles\scripts\javascript\SnippetRunner.jsx" is this.
>// get the SDKCodeSnippetRunner object
var snippetRunner = app.sdkCodeSnippetRunnerObject;
I understand that in xxxx.fr there is defined "sdkCodeSnippetRunnerObject" object and is added to application object but when I tried to find this string in source codes "sdkCodeSnippetRunnerObject" simply didn't exist....
2)How can I run some snippetRunner method?
I wrote this.
>var snippet = snippetRunner.sdkCodeSnippets.item(53);
if (snippet.canRun() == true)
snippet.run();
but it didn't work. 53 should be PlaceFile snippet.
Thanks,
pyso

Inside the .fr the name is formatted as multiple words separated by spaces matching the notation for AppleScript. The capitalization is just a different formatting for JavaScript. For your object, see SnipRun.fr line 1319, below the kSnipRunObjectScriptElement ID.
There are also plenty details in the sdkdocs, e.g. scriptable-plugin.pdf
And Ole is right that these questions are better asked in the SDK forum.
