SubStore

represents the current value of the Store

the current value of the Store is derived from the data of it's parent using the given Lens.

defines how to infer the id of the sub-part from the parent's id.

Job used as parent job on all coroutines started in Handlers in the scope of this Store

defines how to infer the id of the sub-part from the parent's id.

a simple SimpleHandler that just takes the given action-value as the new value for the Store.

Since a SubStore is just a view on a parent holding the real value, it forwards the Update to it, using it's Lens to transform it.

Default error handler printing the error to console.

Factory method to create a SimpleHandler that does not take an Action

Factory method to create a SimpleHandler mapping the actual value of the Store and a given Action to a new value.

factory method to create an EmittingHandler that does not take an action in it's execute-lambda.

Factory method to create a EmittingHandler taking an action-value and the current store value to derive the new value. An EmittingHandler is a Flow by itself and can therefore be connected to other SimpleHandlers even in other Stores.

factory-method to create a History synced with the given Store, so that each update is automatically stored in history.

Creates a new Store that contains data derived by a given Lens.

on a Store of nullable data this creates a Store with a nullable parent and non-nullable value. It can be called using a Lens on a non-nullable parent (that can be created by using the @Lenses-annotation), but you have to ensure, that the resulting Store is never used, when it's parent's value is null. Otherwise, a NullPointerException is thrown.

Creates a new Store containing the element for the given element and idProvider from the original Store's List.

Creates a new Store containing the element for the given index from the original Store's List

Creates a new Store containing the corresponding value for the given key from the original Store's Map.

Creates a new Store from a nullable parent store that either contains the original value or a given default value if the original value was null.

Finds all exactly corresponding ValidationMessages to this Store, which means all messages, which have exactly the same path as the Store.

Finds all corresponding ValidationMessages to this Store which satisfy the filterPredicate-expression.

Finds all corresponding ValidationMessages to this Store, which means all messages, that fit exactly with their path or which are sub-elements of this Stores data model.
