ReadKeyValueFromKeyValuesRepo

open class ReadKeyValueFromKeyValuesRepo<Key, Value>(original: ReadKeyValuesRepo<Key, Value>) : ReadKeyValueRepo<Key, List<Value>> (source)

Adapter that exposes a ReadKeyValuesRepo as a ReadKeyValueRepo mapping each key to a List of values. Each key's associated list of values is retrieved via ReadKeyValuesRepo.getAll.

Parameters

original

The underlying ReadKeyValuesRepo to delegate operations to

Type Parameters

Key

The type of keys

Value

The type of individual values in the one-to-many repo

Functions

asReadCRUDRepo

fun <K, V> ReadKeyValueRepo<K, V>.asReadCRUDRepo(): ReadCRUDFromKeyValueRepo<V, K>

Wraps this ReadKeyValueRepo as a ReadCRUDFromKeyValueRepo, exposing CRUD read operations.

asReadKeyValuesRepo

fun <K, V, VI : Iterable<V>> ReadKeyValueRepo<K, VI>.asReadKeyValuesRepo(): ReadKeyValuesFromKeyValueRepo<K, V, VI>

Wraps this ReadKeyValueRepo (mapping keys to iterables) as a ReadKeyValuesFromKeyValueRepo, exposing a one-to-many read interface.

cached

fun <Key, Value> ReadKeyValueRepo<Key, Value>.cached(kvCache: KVCache<Key, Value>, locker: SmartRWLocker = SmartRWLocker()): ReadKeyValueCacheRepo<Key, Value>

fun <Key, Value> ReadKeyValueRepo<Key, Value>.cached(kvCache: KeyValueRepo<Key, Value>, locker: SmartRWLocker = SmartRWLocker()): FullReadKeyValueCacheRepo<Key, Value>

contains

open suspend override fun contains(key: Key): Boolean

count

open suspend override fun count(): Long

diff

suspend fun <Id, Registered> ReadKeyValueRepo<Id, Registered>.diff(other: Map<Id, Registered>): MapDiff<Id, Registered>

Computes the difference between all entries in this ReadKeyValueRepo and the given other map.

directlyCached

fun <Key, Value> ReadKeyValueRepo<Key, Value>.directlyCached(kvCache: KeyValueRepo<Key, Value>, locker: SmartRWLocker = SmartRWLocker()): DirectFullReadKeyValueCacheRepo<Key, Value>

get

open suspend override fun get(k: Key): List<Value>?

getAll

open suspend override fun getAll(): Map<Key, List<Value>>

Returns all key-value pairs in the repository as a Map. Default implementation iterates all pages using keys and get.

keys

open suspend override fun keys(pagination: Pagination, reversed: Boolean = false): PaginationResult<Key>

This method should use sorted by Keys search and return the PaginationResult. By default, it should use ascending sort for Keys

open suspend override fun keys(v: List<Value>, pagination: Pagination, reversed: Boolean = false): PaginationResult<Key>

This method should use sorted by Keys search and return the PaginationResult. By default, it should use ascending sort for Keys.

maxPagePagination

inline suspend fun ReadKeyValueRepo<*, *>.maxPagePagination(): SimplePagination

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

values

open suspend override fun values(pagination: Pagination, reversed: Boolean = false): PaginationResult<List<Value>>

This method should use sorted by Keys search and return the PaginationResult. By default, it should use ascending sort for Keys

withMapper

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

Wraps this ReadKeyValueRepo with a MapperRepo to expose a mapped ReadKeyValueRepo.

inline fun <FromKey, FromValue, ToKey, ToValue> ReadKeyValueRepo<ToKey, ToValue>.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 }): ReadKeyValueRepo<FromKey, FromValue>

Wraps this ReadKeyValueRepo with inline conversion lambdas to expose a mapped ReadKeyValueRepo.
