Methods

Method	Alerts	Return Type	Description
addChannel(channel)	Alpha	void	This api allows adding channel to data store after it was created. This allows callers to cusmomize channel instance. For example, channel implementation could have various modes of operations. As long as such configuration is provided at creation and stored in summaries (such that all users of such channel instance behave the same), this could be useful technique to have customized solutions without introducing a number of data structures that all have same implementation. This is also useful for scenarios like SharedTree DDS, where schema is provided at creation and stored in a summary. The channel type should be present in the registry, otherwise the runtime would reject the channel. The runtime used to create the channel object should be same to which it is added.
bindChannel(channel)	Alpha	void	Bind the channel with the data store runtime. If the runtime is attached then we attach the channel to make it live.
createChannel(id, type)	Alpha	IChannel	Creates a new channel of the given type.
getAudience()	Alpha	IAudience	Returns the current audience.
getChannel(id)	Alpha	Promise<IChannel>	Returns the channel with the given id
getQuorum()	Alpha	IQuorumClients	Returns the current quorum.
uploadBlob(blob, signal)	Alpha	Promise<IFluidHandle<ArrayBufferLike>>	Api to upload a blob of data.
waitAttached()	Alpha	Promise<void>	Resolves when a local data store is attached.
