Class: SimpleContainer

container.SimpleContainer

Most basic Container implementation where the encryption key is simply passed explicitly.

Hierarchy

Constructors

constructor

new SimpleContainer()

Inherited from

BaseContainer.constructor

Properties

_key

Protected Optional _key: Uint8Array

The key used for encryption. Sub classes must set this property in the unlock method.

Inherited from

BaseContainer._key

Defined in

core/src/container.ts:33


_propertySerializationOptions

_propertySerializationOptions: SerializationOptions[]

Inherited from

BaseContainer._propertySerializationOptions

Defined in

core/src/encoding.ts:163


encryptedData

Optional encryptedData: Uint8Array

Encrypted data

Inherited from

BaseContainer.encryptedData

Defined in

core/src/container.ts:28


encryptionParams

encryptionParams: AESEncryptionParams

Parameters used for encryption of content data

Inherited from

BaseContainer.encryptionParams

Defined in

core/src/container.ts:24

Accessors

kind

get kind(): string

A string representing the objects "type", useful for segmenting storage, among other things. Defaults to the lowercase class name, but can be overwritten by subclasses

Returns

string

Inherited from

BaseContainer.kind

Defined in

core/src/encoding.ts:159

Methods

_fromRaw

Protected _fromRaw(raw): void

Restore values from a raw object. The default implementation simply copies over all iterable properties from the base object. Overwrite this method for properties that require special treatment

Parameters

Name Type
raw any

Returns

void

Inherited from

BaseContainer._fromRaw

Defined in

core/src/encoding.ts:286


_toRaw

Protected _toRaw(version): any

Transform this object into a raw javascript object used for serialization. The default implementation simply copies all iterable properties not included in the [[exlude]] array and calls toRaw on any properties that are themselfes instances of Serializable. This method should be overwritten by subclasses if certain properties require special treatment.

Parameters

Name Type
version undefined | string

Returns

any

Inherited from

BaseContainer._toRaw

Defined in

core/src/encoding.ts:257


clone

clone(): SimpleContainer

Creates a deep clone of the object

Returns

SimpleContainer

Inherited from

BaseContainer.clone

Defined in

core/src/container.ts:85


fromBytes

fromBytes(bytes): SimpleContainer

Deserializes the object from a byte array

Parameters

Name Type
bytes Uint8Array

Returns

SimpleContainer

Inherited from

BaseContainer.fromBytes

Defined in

core/src/encoding.ts:237


fromJSON

fromJSON(json): SimpleContainer

Deserializes the object from a JSON string

Parameters

Name Type
json string

Returns

SimpleContainer

Inherited from

BaseContainer.fromJSON

Defined in

core/src/encoding.ts:223


fromRaw

fromRaw(raw): SimpleContainer

Restores propertiers from a raw object of the same form generated by toRaw. The base implementation blindly copies over values from the raw object via Object.assign so subclasses should explictly process any propertyies that need special treatment.

Also takes are of validation and "upgrading" in case the raw object has an old version. Use the protected _fromRaw method to implement subclass-specific behavior.

Parameters

Name Type
raw any

Returns

SimpleContainer

Inherited from

BaseContainer.fromRaw

Defined in

core/src/encoding.ts:196


getData

getData(): Promise<Uint8Array>

Decrypts and extracts the plain text data from the container. This will usually require unlocking the container first.

Returns

Promise<Uint8Array>

Inherited from

BaseContainer.getData

Defined in

core/src/container.ts:61


lock

lock(): void

Locks the container, removing the possibility to extract the plain text data via getData until the container is unlocked again. Subclasses extending this class must take care to delete any keys or other sensitive data that may have been stored temporarily after unlocking the container.

Returns

void

Inherited from

BaseContainer.lock

Defined in

core/src/container.ts:81


setData

setData(data): Promise<void>

Encrypts the provided data and stores it in the container

Parameters

Name Type
data Uint8Array

Returns

Promise<void>

Inherited from

BaseContainer.setData

Defined in

core/src/container.ts:38


toBytes

toBytes(): Uint8Array

Returns a serialization of the object in form of a byte array

Returns

Uint8Array

Inherited from

BaseContainer.toBytes

Defined in

core/src/encoding.ts:230


toJSON

toJSON(): string

Returns a JSON serialization of the object

Returns

string

Inherited from

BaseContainer.toJSON

Defined in

core/src/encoding.ts:216


toRaw

toRaw(version?): any

Creates a raw javascript object representation of the class, which can be used for storage or data transmission. Also handles "downgrading" to previous versions. Use _toRaw for subclass-specific behavior.

Parameters

Name Type
version? string

Returns

any

Inherited from

BaseContainer.toRaw

Defined in

core/src/encoding.ts:179


unlock

unlock(key): Promise<void>

Unlocks the container, making it possible to extract the plain text data via getData. The type of secret provided will differ based on the encryption scheme used by implemenations.

Parameters

Name Type
key Uint8Array

Returns

Promise<void>

Overrides

BaseContainer.unlock

Defined in

core/src/container.ts:97


validate

validate(): boolean

This is called during deserialization and should verify that all properties have been populated with values of the correct type. Subclasses should implement this method based on their class structure.

Returns

boolean

Inherited from

BaseContainer.validate

Defined in

core/src/encoding.ts:170
