Composite Storage

Represents an in-memory dictionary storage and physical storage. The CompositeStorage instance is not thread safe. Using directly from multiple threads can lead to unexpected behaviors.

To initialize a default CompositeStorage you would use the following lines somewhere central in your application. Then it’s ready to use.

var compositeStore = CompositeStorage()
// by default it is initialized with a MemoryDataStorage() and a PlistCoder()
 do {
 // setting an example store
     let secureKeyValueStore = SecureKeyValueStore()
     try secureKeyValueStore.open(with: "your_encryption_key")
     try self.compositeStore.setPersistentStore(secureKeyValueStorage)
} catch  {
     //error handling
}

You can insert to the CompositeStorage instance.

let testCustomObject = CustomTestStruct()

// put data to compositeStore
 do {
     try self.compositeStore.put(testCustomObject, key: "testCustomObject")
     let returnDataFromMemory = try self.compositeStore.get(CustomTestStruct.self, key: "testCustomObject")
 } catch {
     //error handling
 }

Load data from CompositeStorage

 do {
 let returnData = try self.compositeStore.get(CustomTestStruct.self, key: "testCustomObject")
 } catch {
 //error handling
 }

Remove a key from compositeStore

 do {
     try self.compositeStore.removeData(for: key)
 } catch {
     //error handling
 }
