PHP Class SSLRealtimeModelDeck, sslscrobbler

Generally you would notify the deck of a bunch of SSLTracks (usually from the Serato History file) using notify(), and it would cherry pick relevant entries based on the deck number. After processing the Tracks, various status methods are pollable for the deck's current state and information about what changed. You may also ask the deck information about how long the current track has been playing for, etc.

See also: SSLRealtimeModel for more info on the statuses, transitions and their meanings.

notify() public method

SSL batches writes of track info, but doesn't output them in the natural transition order - that is, sometimes information about the following song appears in the log before closing info on the previous song, as the History File is track oriented, not deck oriented. During notify(), we reorder this information into an order that's transition compatible (that is, row ID ascending order). The implication of sending a bunch of track notifications together (rather than one by one) is that they happen simultaneously, and the end result is what's important rather than every step to get there. As diffs usually only come during track load, change or eject, it would be abnormal to see information about more than 2 tracks on a single deck here, and abnormal for neither of them to be the one currently on the deck. However, it can happen - for example, loading a historical file or starting the monitor half way through a session.
