Functions that set up the simplest version of a state chart that uses the v20150901 implementation (version), a working memory data model, CLJC execution support, and an event queue that requires manual polling.

register!clj/s
(register! {:com.fulcrologic.statecharts/keys [statechart-registry]}
chart-key
chart)Register a statechart chart at chart-key in the registry known by env.
Register a statechart `chart` at `chart-key` in the registry known by `env`.
send!clj/s
(send! {:com.fulcrologic.statecharts/keys [event-queue] :as env} event)Proxy to sp/send! on the event-queue in env.
Proxy to sp/send! on the event-queue in `env`.
simple-envclj/s
(simple-env)(simple-env {:com.fulcrologic.statecharts/keys [data-model execution-model
event-queue working-memory-store
statechart-registry]
:as extra-env})Creates an env that has a local and simple implementation of all required components.
It defaults to standard processing with a flat working memory data model, a manual event queue, local memory registry and memory storage, a statechart invocation processor, the lambda executor, and a v20150901 processor.
extra-env can contain anything extra you want in env, and can override any of the above by
key (e.g. ::sc/data-model).
Returns an env ready to be used with the processor (which is ::sc/processor in env).
Remember to register your charts via (env/register! env k chart) or by using the
::sc/statechart-registry returned in env directly.

chart-src
session-id)Start a statechart that has been previously registered with env as chart-src. The options map
can contain ::sc/session-id or one will be autogenerated. Note: This assumes you're going to send events
via the event queue, and that something is running an event loop on that event queue.
Returns nothing useful, but throws if there is a problem.
