Overview

Entries list

Common usage

This is what’s returned by methods like Feed#entries and Tag#entries.

entries = tag.entries

It’s a simple array so just use it like so:

entries.each { |entry| puts entry }

entries.size  #=> 20

You can also lookup by id:

feeds.entries['ENTRY_ID']

But you can have it load more entries:

entries.more
entries.each { |entry| puts entry }

entries.size  #=> 40

Internal usage

Pass it an Atom URL.

Entries.fetch @client, @client.atom_url(xxx)
