G+ Domain API Google Apps Script Public Posts Scan - api

Question

I'm running a script that scans our domain users G+ posts and flags any post shared publicly and then sends an email notification with a link to the post to the end user. The script was written by someone else who is no longer with the company. I want to change the script so that it will flag any post that does not have "domainRestricted";True.
Here's an output of a scanned post with the type of access associated "domainRestricted":True. This post is shared within the domain.
{
"description":"Shared privately",
"domainRestricted":true,
"kind":"plus#acl"
}
Here's an output example of a scanned post without domainRestricted access. This post is shared with a Circle containing users outside of the domain, essentially Public.
{
"description":"Shared privately",
"kind":"plus#acl"
}
Here's an output example of a scanned post with Public as the access. This post was explicitly shared publicly.
{
"items":[{"type":"public"}],
"description":"Public",
"kind":"plus#acl"
}
I want to change this code, to scan for any posts that does not contain the access "domainRestricted":True.
function checkPublicPosts( userId ) {
var publicPosts = Array();
var pageToken;
try {
do {
Logger.log( 'Scanning posts by ' + userId );
// Search for all Google Plus posts by userId
posts = PlusDomains.Activities.list( userId, 'user', {
maxResults: 100,
pageToken: pageToken
});
// If posts are found, check to see if they are public
if( posts.items ) {
for( var i = 0; i < posts.items.length; i++ ) {
var post = posts.items[i];
var public = false;
if( !post.access.domainRestricted && ( typeof( post.access.items ) != 'undefined' ) ) {
for( var j = 0; j < post.access.items.length; j++ ) {
if( post.access.items[j].type = 'public' ) {
public = true;
j = post.access.items.length;
}
}
}
// If a post is public, add it to the list of public posts for userId
if( public ) publicPosts.push( post );
}
}
// If user has more than 100 posts, continue with the analysis of subsequent batches of 100
pageToken = posts.nextPageToken;
} while (pageToken);
} catch( err ) {
// The code above sometimes fails for unexpected reasons. We
// log this error.
Logger.log( 'Failed on ' + userId + ' with error ' + err );
}
return publicPosts;
}
Can anyone help me?
