Syntax

public static class StoreExtensions

Methods

Dispatch(IDispatchable, string)

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

Declaration

public static void Dispatch(this IDispatchable store, string actionType)

Parameters

Type	Name	Description
IDispatchable	store	The store to dispatch the action to.
string	actionType	The type of the action.

Exceptions

Type	Condition
ArgumentNullException	Thrown when the store is null.
ArgumentNullException	Thrown when the actionType is null or empty.

Dispatch(IDispatchable, ActionCreator)

Dispatches an action from the given creator. This is a shortcut to call the creator and dispatch the action.

Declaration

public static void Dispatch(this IDispatchable store, ActionCreator creator)

Parameters

Type	Name	Description
IDispatchable	store	The store to dispatch the action to.
ActionCreator	creator	The action creator.

Exceptions

Type	Condition
ArgumentNullException	Thrown when the store is null.
ArgumentNullException	Thrown when the creator is null.

DispatchAsyncThunkCoroutine<TPayload, TArg>(IDispatchable, AsyncThunkAction<TPayload, TArg>, CancellationToken)

Dispatches an async thunk action.

This method will dispatch the pending action, then call the thunk, and finally dispatch the fulfilled or rejected action based on the result of the thunk.

Declaration

public static Coroutine DispatchAsyncThunkCoroutine<TPayload, TArg>(this IDispatchable store, AsyncThunkAction<TPayload, TArg> asyncThunkAction, CancellationToken cancellationToken = default)

Parameters

Type	Name	Description
IDispatchable	store	The store to dispatch the action to.
AsyncThunkAction<TPayload, TArg>	asyncThunkAction	The async thunk action to dispatch.
CancellationToken	cancellationToken	The cancellation token.

Returns

Type	Description
Coroutine	The coroutine.

Type Parameters

Name	Description
TPayload	The type of the payload (the result of the thunk).
TArg	The type of the argument to pass to the thunk.

Exceptions

Type	Condition
ArgumentNullException	Thrown when the store is null.
ArgumentNullException	Thrown when the asyncThunkAction is null.

DispatchAsyncThunk<TPayload, TArg>(IDispatchable, AsyncThunkAction<TPayload, TArg>, CancellationToken)

Dispatches an async thunk action.

This method will dispatch the pending action, then call the thunk, and finally dispatch the fulfilled or rejected action based on the result of the thunk.

Declaration

public static Task DispatchAsyncThunk<TPayload, TArg>(this IDispatchable store, AsyncThunkAction<TPayload, TArg> asyncThunkAction, CancellationToken cancellationToken = default)

Parameters

Type	Name	Description
IDispatchable	store	The store to dispatch the action to.
AsyncThunkAction<TPayload, TArg>	asyncThunkAction	The async thunk action to dispatch.
CancellationToken	cancellationToken	The cancellation token.

Returns

Type	Description
Task	A task that represents the asynchronous operation.

Type Parameters

Name	Description
TPayload	The type of the payload (the result of the thunk).
TArg	The type of the argument to pass to the thunk.

Remarks

Dispatching an async thunk action with this method invloves the use of async/await. If your target platform doesn't support async/await, you can use DispatchAsyncThunkCoroutine<TPayload, TArg>(IDispatchable, AsyncThunkAction<TPayload, TArg>, CancellationToken) instead.

Exceptions

Type	Condition
ArgumentNullException	Thrown when the store is null.
ArgumentNullException	Thrown when the asyncThunkAction is null.

Type Parameters

Dispatch<TPayload>(IDispatchable, ActionCreator<TPayload>, TPayload)
