LceTerminated<DATA extends Object> class

A special state that may be used to terminate state emission in cases we always need a latest state to proceed For example we have a view that subscribes to LceState for a resource identified with some PARAMS. Than a delete operation is performed on that resource and it is not available anymore. The one may emit LceTerminated to do a special processing (e.g. close the corresponding view) instead of doing it through server request that will return a Not found error and doing a special case processing afterwards. Also useful when onComplete from state-emitter can't be processed by the end-subscriber. For example LiveData does not emit completion and caches the latest emission. So converting stream to LiveData will loose Rx completion logic.

Properties

data → DATA?

State data

final

dataIsValid → bool

A property that is evaluated internally and may mean that data being emitted is stall, invalidated or otherwise 'not-so-valid' until some further emission (say after network reload).

final, inherited

hashCode → int

The hash code for this object.

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toError(Exception error) → LceError<DATA>

Transfers to LceError state with error preserving data

inherited

toLoading([LoadingType type = LoadingType.loading]) → LceLoading<DATA>

Transfers to LceLoading state with loading type preserving data

inherited

toString() → String

A string representation of this object.

override

when<T extends Object>({required T loading(LceLoading<DATA> state), required T content(LceContent<DATA> state), required T error(LceError<DATA> state), T terminated()?}) → T

Emulates sealed class with every state callback required except terminated. Override it if you expect termination or leave empty to throw exception

override

whenElse<T extends Object>({T loading(LceLoading<DATA> state)?, T content(LceContent<DATA> state)?, T error(LceError<DATA> state)?, T terminated()?, required T onElse(LceState<DATA> state)}) → T

Emulates sealed class with only one onElse callback required. Every unset callback will be routed to onElse case.

override

Operators

operator ==(Object other) → bool

The equality operator.
