Given an instance of EquivalentKeyMap, returns its internal value pair tuple
for a key, if one exists. The tuple members consist of the last reference
value for the key (used in efficient subsequent lookups) and the value
assigned for the key at the leaf node.

return: {?Array} Value pair, if exists.
param: {EquivalentKeyMap} instance EquivalentKeyMap instance.

redux_createStore(reducer, preloadedState, enhancer) X-Ref

Creates a Redux store that holds the state tree.
The only way to change the data in the store is to call `dispatch()` on it.

There should only be a single store in your app. To specify how different
parts of the state tree respond to actions, you may combine several reducers
into a single reducer function by using `combineReducers`.

param: {Function} reducer A function that returns the next state tree, given
param: {any} [preloadedState] The initial state. You may optionally specify it
param: {Function} [enhancer] The store enhancer. You may optionally specify it
returns: {Store} A Redux store that lets you read the state, dispatch actions

ensureCanMutateNextListeners() X-Ref

This makes a shallow copy of currentListeners so we can use
nextListeners as a temporary list while dispatching.

This prevents any bugs around consumers calling
subscribe/unsubscribe in the middle of a dispatch.

getState() X-Ref

Reads the state tree managed by the store.

returns: {any} The current state tree of your application.

subscribe(listener) X-Ref

Adds a change listener. It will be called any time an action is dispatched,
and some part of the state tree may potentially have changed. You may then
call `getState()` to read the current state tree inside the callback.

You may call `dispatch()` from a change listener, with the following
caveats:

1. The subscriptions are snapshotted just before every `dispatch()` call.
If you subscribe or unsubscribe while the listeners are being invoked, this
will not have any effect on the `dispatch()` that is currently in progress.
However, the next `dispatch()` call, whether nested or not, will use a more
recent snapshot of the subscription list.

2. The listener should not expect to see all state changes, as the state
might have been updated multiple times during a nested `dispatch()` before
the listener is called. It is, however, guaranteed that all subscribers
registered before the `dispatch()` started will be called with the latest
state by the time it exits.

param: {Function} listener A callback to be invoked on every dispatch.
returns: {Function} A function to remove this change listener.

dispatch(action) X-Ref

Dispatches an action. It is the only way to trigger a state change.

The `reducer` function, used to create the store, will be called with the
current state tree and the given `action`. Its return value will
be considered the **next** state of the tree, and the change listeners
will be notified.

The base implementation only supports plain object actions. If you want to
dispatch a Promise, an Observable, a thunk, or something else, you need to
wrap your store creating function into the corresponding middleware. For
example, see the documentation for the `redux-thunk` package. Even the
middleware will eventually dispatch plain object actions using this method.

param: {Object} action A plain object representing “what changed”. It is
returns: {Object} For convenience, the same action object you dispatched.

replaceReducer(nextReducer) X-Ref

Replaces the reducer currently used by the store to calculate the state.

You might need this if your app implements code splitting and you want to
load some of the reducers dynamically. You might also need this if you
implement a hot reloading mechanism for Redux.

param: {Function} nextReducer The reducer for the store to use instead.
returns: {void}

observable() X-Ref

Interoperability point for observable/reactive libraries.

returns: {observable} A minimal observable of state changes.

observeState() X-Ref

No description

warning(message) X-Ref

Prints a warning in the console if it exists.

param: {String} message The warning message.
returns: {void}

assertReducerShape(reducers) X-Ref

combineReducers(reducers) X-Ref

Turns an object whose values are different reducer functions, into a single
reducer function. It will call every child reducer, and gather their results
into a single state object, whose keys correspond to the keys of the passed
reducer functions.

param: {Object} reducers An object whose values correspond to different
returns: {Function} A reducer function that invokes every reducer inside the

bindActionCreator(actionCreator, dispatch) X-Ref

No description

bindActionCreators(actionCreators, dispatch) X-Ref

Turns an object whose values are action creators, into an object with the
same keys, but with every function wrapped into a `dispatch` call so they
may be invoked directly. This is just a convenience method, as you can call
`store.dispatch(MyActionCreators.doSomething())` yourself just fine.

For convenience, you can also pass an action creator as the first argument,
and get a dispatch wrapped function in return.

param: {Function|Object} actionCreators An object whose values are action
param: {Function} dispatch The `dispatch` function available on your Redux
returns: {Function|Object} The object mimicking the original object, but with

compose() X-Ref

Composes single-argument functions from right to left. The rightmost
function can take multiple arguments as it provides the signature for
the resulting composite function.

param: {...Function} funcs The functions to compose.
returns: {Function} A function obtained by composing the argument functions

applyMiddleware() X-Ref

Creates a store enhancer that applies middleware to the dispatch method
of the Redux store. This is handy for a variety of tasks, such as expressing
asynchronous actions in a concise manner, or logging every action payload.

See `redux-thunk` package as an example of the Redux middleware.

Because middleware is potentially asynchronous, this should be the first
store enhancer in the composition chain.

Note that each middleware will be given the `dispatch` and `getState` functions
as named arguments.

param: {...Function} middlewares The middleware chain to be applied.
returns: {Function} A store enhancer applying the middleware.

isCrushed() X-Ref

No description

createRegistrySelector(registrySelector) X-Ref

Creates a selector function that takes additional curried argument with the
registry `select` function. While a regular selector has signature
```js
( state, ...selectorArgs ) => ( result )
```
that allows to select data from the store's `state`, a registry selector
has signature:
```js
( select ) => ( state, ...selectorArgs ) => ( result )
```
that supports also selecting from other registered stores.

return: {Function} Registry selector that can be registered with a store.
param: {Function} registrySelector Function receiving a registry `select`

createRegistryControl(registryControl) X-Ref

Creates a control function that takes additional curried argument with the `registry` object.
While a regular control has signature
```js
( action ) => ( iteratorOrPromise )
```
where the control works with the `action` that it's bound to, a registry control has signature:
```js
( registry ) => ( action ) => ( iteratorOrPromise )
```
A registry control is typically used to select data or dispatch an action to a registered
store.

When registering a control created with `createRegistryControl` with a store, the store
knows which calling convention to use when executing the control.

return: {Function} Registry control that can be registered with a store.
param: {Function} registryControl Function receiving a registry object and returning a control.

controls_select(storeKey, selectorName, ...args) X-Ref

Note: This control synchronously returns the current selector value, triggering the
resolution, but not waiting for it.

return: {Object} The control descriptor.
param: {string} storeKey The key for the store the selector belongs to.
param: {string} selectorName The name of the selector.
param: {Array} args Arguments for the selector.

controls_resolveSelect(storeKey, selectorName, ...args) X-Ref

Dispatches a control action for triggering and resolving a registry select.

Note: when this control action is handled, it automatically considers
selectors that may have a resolver. In such case, it will return a `Promise` that resolves
after the selector finishes resolving, with the final result value.

return: {Object} The control descriptor.
param: {string} storeKey      The key for the store the selector belongs to
param: {string} selectorName  The name of the selector
param: {Array}  args          Arguments for the selector.

param: {Array}  args        Arguments for the dispatch action.
