Sharepoint: SPAttachmentCollection a collection of what exactly?

Question

Take the following code snippet:

SPAttachmentCollection attachments = item.Attachments ; 

What exactly is SPAttachmentCollection a collection of? Most collections tell you what they're a collection of.... but remember the golden rule of SharePoint - that's right, if its possible to break, its already broken.

In case you're wondering an SPAttachment object does not exist. So could someone please enlighten me, what is the attachment object I am looking for.

Thanks

Note that the linked post complicates things. The preferred usage is found in the comments:

var attachments in item.Attachments;
foreach (string fileName in attachments)
{
    SPFile file = web.GetFile(attachments.UrlPrefix + fileName);
    // Do something ...
}

"the SPAttachmentCollection is simply an array of strings representing the file name of each attachment"
