IdStorage class abstract interface

The mechanical store behind a registry: id codes per id type, plus counters.

Every method answers with a value — trouble comes back as a Left, never as a throw — so adapters can be swapped without changing error handling, and the counters exist so generated ids do not have to re-scan the whole store.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

Methods

add({required String idType, required String idCode}) → Future<Either<IdStorageFailure, Unit>>

Records idCode under idType, keeping whatever is already stored.

clear() → Future<Either<IdStorageFailure, Unit>>

Drops every code and every counter.

codesFor({required String idType}) → Future<Either<IdStorageFailure, Set<String>>>

Every code stored under idType.

contains({required String idType, required String idCode}) → Future<Either<IdStorageFailure, bool>>

Whether idCode is stored under idType.

counterFor({required String idType}) → Future<Either<IdStorageFailure, int>>

The counter stored for idType, or 0 when none was ever set.

idTypes() → Future<Either<IdStorageFailure, Set<String>>>

Every id type holding at least one code.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

remove({required String idType, required String idCode}) → Future<Either<IdStorageFailure, Unit>>

Removes idCode from idType; removing an absent code is a success.

setCounter({required String idType, required int value}) → Future<Either<IdStorageFailure, Unit>>

Stores value as the counter for idType.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
