ReadCRUDFromKeyValueRepo

open class ReadCRUDFromKeyValueRepo<RegisteredType, IdType>(original: ReadKeyValueRepo<IdType, RegisteredType>) : ReadCRUDRepo<RegisteredType, IdType> (source)

Adapter that exposes a ReadKeyValueRepo as a ReadCRUDRepo. Maps CRUD read operations to the underlying key-value repository operations.

Parameters

original

The underlying ReadKeyValueRepo to delegate operations to

Type Parameters

RegisteredType

The type of objects stored in the repository

IdType

The type of identifiers (keys) used to reference stored objects

Functions

Link copied to clipboard
fun <K, V> ReadCRUDRepo<K, V>.asReadKeyValueRepo(): ReadKeyValueFromCRUDRepo<V, K>

Wraps this ReadCRUDRepo as a ReadKeyValueFromCRUDRepo, exposing CRUD IDs as keys and CRUD objects as values in a ReadKeyValueRepo.

open suspend override fun contains(id: IdType): Boolean

Returns true if an object with the given id exists in the repository.

Link copied to clipboard
open suspend override fun count(): Long

Returns the total count of objects stored in the repository.

Link copied to clipboard
suspend fun <Id, Registered> ReadCRUDRepo<Registered, Id>.diff(other: Map<Id, Registered>): MapDiff<Id, Registered>

Computes the difference between this ReadCRUDRepo and a map of items. Retrieves all items from the repository and compares them with the provided map.

open suspend override fun getAll(): Map<IdType, RegisteredType>

Returns all objects in the repository as a map of ID to object. Default implementation iterates all pages using getIdsByPagination and getById.

Link copied to clipboard
open suspend override fun getById(id: IdType): RegisteredType?

Returns the object associated with the given id, or null if not found.

Link copied to clipboard
open suspend override fun getByPagination(pagination: Pagination): PaginationResult<RegisteredType>

Returns a paginated list of all objects in the repository.

Link copied to clipboard
open suspend override fun getIdsByPagination(pagination: Pagination): PaginationResult<IdType>

Returns a paginated list of all IDs in the repository.

Link copied to clipboard
inline suspend fun ReadCRUDRepo<*, *>.maxPagePagination(): SimplePagination

Creates a pagination starting from the first page with size equal to the total count of items in this ReadCRUDRepo. This effectively creates a single page containing all items.

inline fun <FromKey, FromValue, ToKey, ToValue> ReadCRUDRepo<ToValue, ToKey>.withMapper(mapper: MapperRepo<FromKey, FromValue, ToKey, ToValue>): ReadCRUDRepo<FromValue, FromKey>

Wraps this ReadCRUDRepo with a mapper to expose different key and value types.

inline fun <FromKey, FromValue, ToKey, ToValue> ReadCRUDRepo<ToValue, ToKey>.withMapper(noinline keyFromToTo: suspend FromKey.() -> ToKey = { this as ToKey }, noinline valueFromToTo: suspend FromValue.() -> ToValue = { this as ToValue }, noinline keyToToFrom: suspend ToKey.() -> FromKey = { this as FromKey }, noinline valueToToFrom: suspend ToValue.() -> FromValue = { this as FromValue }): ReadCRUDRepo<FromValue, FromKey>

Wraps this ReadCRUDRepo with custom conversion functions for keys and values.
