ctx-handler->interceptorclj/s
(ctx-handler->interceptor handler-fn)Returns an interceptor which wraps the kind of event handler given to reg-event-ctx.
These advanced handlers take one argument: context and they return a modified context.
Example:
(fn [context]
(enqueue context [more interceptors]))
Returns an interceptor which wraps the kind of event handler given to `reg-event-ctx`.
These advanced handlers take one argument: `context` and they return a modified `context`.
Example:
(fn [context]
(enqueue context [more interceptors]))db-handler->interceptorclj/s
(db-handler->interceptor handler-fn)Returns an interceptor which wraps the kind of event handler given to reg-event-db.
These handlers take two arguments; db and event, and they return db.
(fn [db event]
....)
So, the interceptor wraps the given handler:
- extracts two
:coeffectskeys: db and event - calls handler-fn
- stores the db result back into context's
:effects
Returns an interceptor which wraps the kind of event handler given to `reg-event-db`.
These handlers take two arguments; `db` and `event`, and they return `db`.
(fn [db event]
....)
So, the interceptor wraps the given handler:
1. extracts two `:coeffects` keys: db and event
2. calls handler-fn
3. stores the db result back into context's `:effects`fx-handler->interceptorclj/s
(fx-handler->interceptor handler-fn)Returns an interceptor which wraps the kind of event handler given to reg-event-fx.
These handlers take two arguments; coeffects and event, and they return effects.
(fn [coeffects event]
{:db ...
:fx ...})
Wrap handler in an interceptor so it can be added to (the RHS) of a chain:
- extracts
:coeffects - call handler-fn giving coeffects
- stores the result back into the
:effects
Returns an interceptor which wraps the kind of event handler given to `reg-event-fx`.
These handlers take two arguments; `coeffects` and `event`, and they return `effects`.
(fn [coeffects event]
{:db ...
:fx ...})
Wrap handler in an interceptor so it can be added to (the RHS) of a chain:
1. extracts `:coeffects`
2. call handler-fn giving coeffects
3. stores the result back into the `:effects`inject-global-interceptorsclj/s
(inject-global-interceptors state)An interceptor which adds registered global interceptors to the context's queue.
NOTE: :queue is a Clojure.lang.PersistentQueue and not a vector.
