Methods

List of methods on this class
Method	Modifiers	Description
create(runtime, id)		Creates a local version of the channel. Calling attach on the object later will insert it into the object stream.
load(runtime, id, services, branchId, attributes)		Loads the given channel. This call is only ever invoked internally as the only thing that is ever directly loaded is the document itself. Load will then only be called on documents that were created and added to a channel.
