StorageDriver

Abstract Storage Driver API

Describes both permanent (database, filesystem) and temporary (cache, memory) storage methods. SDK actively uses both storage strategies distinguished by name: * storage - permanent storage * cache - temporary storage

Example

write(driver = storage, meta = StorageMeta(room = "323", topic = "dinner"), data = serialize(mapOf(Pair("foo", "boo"))))

val supperTry1 = read(driver = storage, meta = StorageMeta(room = "323", topic = "supper"))

assertEquals(deserialize(LinkedHashMap::class.java, supperTry1.toString()), mapOf(Pair("boo", "woo")))

val supperTry2 = read(driver = storage, meta = StorageMeta(room = "323", topic = "supper"))

assertEquals(deserialize(LinkedHashMap::class.java, supperTry2.toString()), null)

val dinnerTry1 = take(driver = storage, meta = StorageMeta(room = "323", topic = "dinner"))

assertEquals(deserialize(LinkedHashMap::class.java, dinnerTry1.toString()), null)

val dinnerTry2 = take(driver = storage, meta = StorageMeta(room = "323", topic = "dinner"))

assertEquals(deserialize(LinkedHashMap::class.java, dinnerTry2.toString()), null)
